1. Introduction
Dear User, thank you for choosing an Alpinestars Product!
The Tech-Air®5 System (hereinafter referred to as “System” and/or “Tech-Air®5 System”) is
an active safety system for mainstream/recreational motorcycling, which offers protection
to a motorcycle user both as a rider or passenger. In the event of an accident or other
triggering event, the System provides complete upper body protection as it covers the user’s
shoulder, chest, ribs and full back, regardless of the type of motorcycle used. The System is
designed to function in both road riding and light off-road riding situations (subject to the
Off-Road limitations indicated in Section 3 below),
When Race Mode is activated, it can also be used on a closed race track within
the conditions and limitations delineated in this Guide.
Tech-Air®5 System consists of a standalone vest which is designed to protect from impacts
occurring during an accident. It does not provide any protection against possible abrasion
during an accident, therefore, the System must be always used in combination with an outer
protective garment, compatible with the System (for further information see Section 8).
Provides critical information which, if not followed, may cause injury,
death, System malfunction or non-function, and/or an exaggerated
expectation of the Tech-Air®5 System’s abilities.
The System, including its components, are technologically advanced
pieces of motorcycling safety equipment and should not be treated
like a normal motorcycle garment. Similar to one’s motorcycle,
the System and its components must be cared for, serviced and
maintained, so that they may function correctly.
The Tech-Air®5 System does not offer the Dual Charge Concept. Once
the airbag has deployed there’s no further airbag charge. User is
without further airbag protection until the System is serviced.
The System MUST be used in combination with an outer protective
garment, compatible with the System (Section 8).
It is essential to read this Guide carefully, to understand it completely
and to follow the advice and warnings. If you have any questions
regarding the equipment contact Tech-Air®Support (Section 19).

2. Principles of Operation
The System consists of an Airbag Electronic Control Unit (with built-in sensors) integrated
into the back protector, (Figure 1). The cluster of sensors consists of 3 accelerometers
and 3 gyroscopes. These six sensors monitor the user’s body for shocks or unexpected
movements. In the event the user’s body is subject to a high and/or sudden amount of
energy, the System will deploy. This may occur when the motorcycle is involved in an
accident, such as when the motorcycle collides with another vehicle or object, when the
rider loses control or when the rider falls off the motorcycle.
The System is equipped with a Bluetooth Low Energy (BLE) device located in the electronic
control unit. The BLE allows the System to connect directly to a mobile phone in order to
receive important information from the System, while also permitting the users to access
a number of other functions (for further information see “Tech-Air®App” in Section 17).
3. Tech-Air®Envelope of Protection
In general, there are three basic factors that determine whether an airbag system will
provide protection to a user:
• Whether the forces experienced by the user during an event (such as an accident) occur
within an area covered by the airbag; and
• Whether the airbag deploys before the user collides with a vehicle, an obstacle or the
ground.
• Whether the airbag deploys before the user collides with parts or accessories of his/her
own motorcycle. For example, mirrors, windscreens or tank bags.
To provide protection to a user, an airbag system must be fully deployed. The deployment
time consists of the time for the sensors to detect the dangerous event, plus the time it
takes to fill the airbag fully with gas, which, for the System is about 40 milliseconds (ms)
maximum. The time to deploy the airbag depends on the type of accident, the type of
motorcycle (e.g. scooter, custom, sports) and the speed involved, amongst other things.
Figure 1 – Sensor Location
Sensors
(Front) (Back)
To connect the System to the mobile phone via Bluetooth, remember to
activate the Bluetooth module within your phone and to download the Tech-
Air®App available at Android Play Store or at Apple Store.
User must always ensure via the App that the System is running the most up
to date software release.
When the System is in Race Mode it stays active and ready to deploy
when riding at 100km/h and above. Should User stop or reduce the
speed under 100km/h for an extended period of time, the System
will reperform the System Check so it will not activate in case of an
accident.
RACE MODE: Tech-Air®5 System comes with two different algorithms that permit
the use of the System on both streets and light off-road paths (the “Street
Mode”) and race tracks (the “Race Mode”). User can easily switch between these
two modes by using the Tech-Air®App.
System must be used in Street Mode when riding outside race tracks,
as Street Mode operation differs from Race Mode and vice versa.

The System provides impact protection for those areas where airbag coverage is shown in
Figure 2.
(Front) (Back)
Figure 2
Area of Airbag
coverage
No product can provide complete protection from injury (or death),
or damage to persons or property in the event of a fall, accident,
collision, impact, loss of control or other event.
WARNING!
The System provides only limited impact protection against forces in
the areas of airbag coverage as depicted in Figure 2. No guarantee is
given that the System will prevent injuries (including severe or fatal
injuries) inside and/or outside the areas of airbag coverage or the
Envelope of Protection.
The System cannot prevent accidents or injuries to the user.
No protective device, including the System, can provide protection
against all possible sources of injury and therefore cannot provide
complete protection against injuries.
WARNING!
WARNING!
WARNING!
For Tech-Air®5 System the Envelope of Protection includes crashes against obstacles and
loss of control crashes (commonly referred as ‘low-side’ and ‘high-side’).
The “Envelope of Protection” is a term used to generally describe situations and/or
circumstances where the System may provide protection denoted as “inside the Envelope”,
and those where it will not, denoted as “outside the Envelope”.
The System protects both the rider and the passenger wearing the System in the event of
an accident or other triggering events; however, like any other product, there are limitations
to the protection it can provide.
IMPORTANT! If the speed of the vehicle is less than 25km/h (15 mph), the System may
not deploy at the time of the collision/crash, but may deploy if the rider or
passenger suddenly falls from the motorcycle after the impact.
Wearing the System is not a substitute for wearing other protective
motorcycling clothing and gear. To provide full potential protection,
the System must always be worn in conjunction with suitable
motorcycling gear and apparel that covers the rider from head to toe,
including a helmet, protectors, boots, gloves, and other appropriate
protective equipment.
WARNING!
Envelope of Protection for Loss of Control Crashes
A Loss of Control Crash often results in the motorcycle falling over during riding. This
commonly happens when tire grip on the roadway is lost during a turn or heavy braking.
The user does not need to be involved in a crash for the System to
deploy. For example, the System will deploy if the user falls while
wearing the System, such as when dismounting from the motorcycle.
These types of “non-riding” deployments are not failures of the
System.

Motorcycle Type
The Tech-Air®5 System can be utilized by riders or passengers on any type of motorcycle,
including electric motorcycles.
Always make sure to select the Street Mode when riding on roads.
Only use Race Mode for closed race track use.
WARNING!
IMPORTANT!
IMPORTANT!
Figure 3 outlines the Envelope of Protection where the Tech-Air®5 System
is expected to inflate before the user’s body contacts an obstacle. At speeds
above 25km/h the System will deploy regardless of the impact angle, but
outside the Envelope of Protection the System may not be fully inflated
before there is contact between the obstacle and the user.
If Race Mode is selected, the System may not deploy before the
first impact, but may deploy if the rider suddenly falls from the
motorcycle after the impact, regardless of the impact angle.
The above parameters are valid for both the rider and passenger.
Arrival Speed From 25km/h (15mph)
to 50km/h (31mph)
Impact Angle (Fig 3) From 45° to 135°

The above parameters are valid for both rider and passenger.
In Street Mode, Envelope of Protection for Crashes Where a Vehicle Strikes a
Stationary Motorcycle:
IMPORTANT! There are some limitations on the deployment of Tech-Air®5 System even
inside the Envelope of Protection (like a high impact angle on a crash
against an obstacle, or low impact forces). In general, the System is not
expected to deploy if the impact energy is too low.

9EN
Light Off-Road Riding
The Tech-Air®5 System may be used off-road IN A LIMITED CAPACITY riding on gravel roads
only. For the purpose of using the System off-road, the definition of a gravel road is:
• An unpaved road surfaced with gravel.
• Has a minimum width of 4m (13ft).
• Has no gradients +/-30%.
• Has no ruts, steps or holes greater than 50cm (19.5”) in depth.
Since the System is sensitive to sudden body movements and shocks,
the System is to be used ONLY for motorcycling within the conditions
and limitations delineated above. The System is NOT for use in:
a. Any racing or competitive events, unless the Race Mode is selected;
b. Enduro, Motocross, or Supermoto events;
c. Motorcycle stunts; or
d. Side skidding, wheelies, etc.;
e. ANY non-motorcycling activities.
Due to shocks, movement and/or other input detected and/or
received by the System while in use, although unlikely, the System
may deploy even though there is no crash event.
The System’s working temperature is between -20° and +50° (-4°F
to 122°F).
Do not use the System 4000 meters above sea level as low pressure
may damage the internal battery.
Depending on the motorcycle type, for example a scooter or trials
bike, it cannot be guaranteed that the System will inflate before the
user collides with parts of the motorcycle, or other objects.
Wearing the System is not a substitute for wearing other protective
motorcycling clothing and gear. To offer full potential protection
the System must always be worn in conjunction with suitable
motorcycling gear and apparel that covers the rider from head to
toe, including a helmet, protectors, boots, gloves, jacket, and other
appropriate protective equipment.

IMPORTANT! The chances of falling off a motorcycle are notably higher when riding off-
road, particularly when a rider is inexperienced. Even when stopped, a fall
may cause the System to deploy, leaving the user without protection until
the System is returned and recharged (see Section 16).
Tech-Air®App permits user to temporarily disable the System protection if,
for instance, the user is undertaking heavy off-road riding. The System cannot
be turned on again with the App but only by means of simply opening and
closing again the Front Flap.

13 EN
8. Compatible outer garment
The Tech-Air®5 System must be used with an outer protective garment as the vest is not
abrasion resistant. It is generally recommended to the user to choose an outer protective
garment so that, when worn over Tech-Air®5 System, it does not cause discomfort and does
not prevent the functionality of the System.
The System can be used with any abrasion resistant garment that covers the upper body
that is designed for two wheeled motor vehicles provided that the garment has sufficient
space to allow for the expansion of the airbag after the deployment.
Alpinestars offers many Tech-Air®compatible outer garments (such as Tech-Air®Compatible
1 and 2 piece suits, jackets, and the new generation of Tech-Air®Ready garments, both of
which are specifically designed with stretch panels to accommodate the volume of the
inflated airbag after deployment).
Follow the procedure described below to check if your garment is compatible with the
System. Remember to ensure that you select an outer garment that has the proper fit
and should any protectors be present on such garment, that the protectors are correctly
positioned. If the garment you have chosen is a leather garment, it is highly recommended
that it has stretch panels to accommodate the inflated airbag after deployment.
Upon inflation, the Tech-Air®5 System’s airbag covers the shoulder, chest, ribs and fullback
area, accordingly the System must not be used inside of a leather suit or a 2 piece leather
suit, unless such leather suit or 2 piece leather suit has sufficient space to accommodate
the inflation of the airbag, as shown below, and it’s not too tight in the crotch area in order
to prevent discomfort in case of deployment.
Vest Size Int. Size User’s Waist to Shoulder length Suggested Height Range
XS 38-40 Up to 43cm (16.9”) Up to 164cm
S 42-44 Up to 46cm (18.1”) Up to 175cm
M 46-48 Up to 48cm (18.9”) Up to 182cm
L 50-52 Up to 50cm (19.7”) Up to 190cm
XL 54-56 Up to 50cm (19.7”) Up to 190cm
2XL 58-60 Up to 52cm (20.5”) Up to 198cm
3XL 62 Up to 52cm (20.5”) Up to 198cm
4XL 64 Up to 52cm (20.5”) Up to 198cm
The Tech-Air®5 System must ALWAYS be used with a correctly fitting
outer garment of the user’s appropriate body size. Use of the System
with the incorrect size of an outer garment, or not compliant with
the size check recommendations above, may result in the System
malfunction or failure and injury, including severe injury and/or
death.
WARNING!
A
B
A - Chest measure B - Garment width
IMPORTANT! When the System is used with an outer garment, other than those
specifically designed for Tech-Air®Systems by Alpinestars, the user must
verify if the outer garment provides a sufficient inner volume able to
contain the deployed airbag as follows:
1. Measure the circumference of the chest
2. Measure the garment width on the chest region

9. System Installation and Fitting
To use the Tech-Air®5 System with an outer garment the user must go through the
following steps:
1. Put on the System, close the Magnetic Zip Closure (1) from bottom to the top.
2. Close the Front Flap (2) with the Alpinestars logo taking care to correctly attach the hook-
and-loop patches, as shown in Figure 8; the System automatically turns on as soon as the
Front Flap is attached to the hook-and-loop patch.
3. Once the Front Flap (2) has been correctly closed, check the LED Display (3) to verify
that the System has turned on and that has started correctly (see “Display Indications” in
Section 13). In particular, the user must verify that after the System starts-up, no system
fault is present.
4. Once verified the regular functioning of the System, signaled by the green (3a) or the
yellow (3b) and green (3a) LEDs, the user may proceed to put on the outer garment taking
care that the System remains well fitted underneath the outer garment, and that all fits
perfectly in place. Particular care must be taken to the shoulder areas of the System which
must be correctly positioned within the sleeves of the outer garment.
5. Once the System has been correctly installed, fasten the outer garment.

It is imperative that the System is fitted correctly in order to provide
the maximum potential protection in an accident. Outer garment
which are too small will cause severe discomfort when the System is
inflated, outer garment which are too large may not hold the System
in place during a fall or accident. In case of doubts or questions
regarding fit, seek advice from an Alpinestars dealer.
Always ensure that the Front Flap is open when the Tech-Air®5
System is not worn by the user; check the LED Display (3) to verify
that the System is not turned on.
WARNING!
WARNING!
Once the System is switched on and the System Check has been successfully passed (see
“Display Indications” in Section 13), the Tech-Air®5 System is ready to deploy as explained
under Section 3 above. The System also activates if the user experiences a loss of control
of the motorcycle which may lead to a fall. A fall from the motorcycle when stopped, may
also activate the System.

10. Transportation of Objects Inside the outer garment
When using an outer garment, consideration needs to be given to the objects which may be
placed inside its pockets. For example:
- Sharp or pointed objects placed in pockets may pierce the airbag and compromise inflation.
- Bulky objects may limit the airbag expansion after deployment, potentially reducing the
effectiveness of the airbag and/or making the System feel much tighter when inflated,
possibly increasing discomfort or causing distraction or injury.
11. Battery Charging
Tech-Air®5 System is supplied with a wall USB Charger (13), a Magnetic Charging Cable (12)
and a Micro USB Adapter (11), for an easy and fast plug-in to the Micro USB Port (10).
Wall USB Charger (13) is supplied with 4 different plugs to adapt to the most common
power sources.
Fully charge the System before the first use. To do this, connect the supplied Magnetic
Charging Cable, or a standard Micro USB charging cable, to the Micro USB Port (10) present
on the upper part of System. Once on charge, the LED display (3) will display a different
combination of solid and blinking LEDs, according to the description provided in “LED
Indications” (Section 13).
15 EN
Under NO circumstances should a user attempt to transport objects
of ANY size or shape, including sharp or pointed objects, stuffed
inside the outer garment, as they may cause injury to the user and/
or damage to the airbag. Only blunt objects should be transported
in the outer garment provided that they fit completely inside the
pockets.
Do not leave the System unattended while charging the battery.
Charge only in a dry location with a temperature range of 0°C to
40°C (32°F – 104°F).
WARNING!
WARNING!
Users should note that the System has been tested to be safe when used
in combination with backpacks (worn over the outer garment) loaded up
to a maximum of 6kg (approximately 13 pounds) in weight.

IMPORTANT!
Particular attention should be paid to the contents of the internal outer
garment’s breast pocket, if any. ONLY flat objects such as wallet or mobile
phone should be stored within this pocket.
Always connect the proper plug to USB Charger (13), correctly fitting the
power source available; always check that the plug is properly connected to
the USB Charger (13) before connecting to the power source.
While charging, always be sure that the USB Charger (13) is connected to a
power source sufficiently near to Tech-Air®5 System, and be sure that the
power source is always easily accessible.
The battery will only recharge when the ambient temperature is between
0°C and 40°C (32°F – 104°F).
If the battery is not periodically charged, it may take longer fully charge.
Charging and Use Times
Approximately 4 hours are required to recharge a discharged battery with the supplied
USB Charger (13), with exception of the first battery charge which may require a longer
time (approx. 12 hours). A fully charged battery will provide approximately 30 hours of
use. If limited time is available, charging the battery for approximately 1 hour will provide
approximately 7 to 8 hours of use.
The System may be charged by connecting it to a computer, or to an
alternative Micro USB charger. However, if the current output is under 1
Ampere, the charging times will be longer than those stated above.

12. System Operation
a) Turning On “Street Mode” and “Race Mode”
To turn on the System, zip up the Magnetic Zip Closure (1) and close the Front Flap (2)
with Alpinestars logo taking care that hook-and-loop patches are correctly attached. An
internal magnetic switch will detect that the Front Flap (2) is closed and the System will
turn on. At this point, the user MUST check the LED Display (3) to verify that the System
starts correctly. See “Display Indications” in Section 13 below for the meanings of the LED
indicator lights.
b) System Check and activation for “Street Mode” and “Race Mode”
After the System is turned on correctly, the System starts performing a System Check. This
will be indicated by the solid yellow (3b) and green (3a) LED indicator lights. During such a
System Check the System will not deploy. This phase may take several seconds.
Whilst the System Check is being performed the System is looking for the body movements
to conduct one or all of the following activities:
• Walking (including up and down stairs)
• Mounting the motorcycle
• Riding the motorcycle.
If the System Check is passed a solid green (3a) LED indicator light will illuminate.
Note that the following activities are unlikely to pass the System Check:
• Zipping up the jacket without wearing it
• Standing still
• Sitting down – INCLUDING on the motorcycle with the engine at idle.
16 EN
In order to activate the Tech-Air®5 System, the Front Flap (2) must
be correctly closed taking care that the hook-and-loop patches are
correctly attached.
WARNING!
If the System does not power on (no LED Indications illuminate) first check
that the Front Flap (2) has been correctly closed, and be sure that the
battery has charge. If the problem persists, contact Tech-Air®Support (see
Section 19 “Tech-Air®Support”).
Tip:
In case of use of a charger different from that supplied with the
System, for a safe operation always insure that the used USB charger
is compliant to EN 62368-1 as a class 1 (ES1) and class 1 (PS1) or 2
(PS2) power source, with a maximum output current of 2 Amperes.
The System should be recharged as soon as possible when the red
Battery Level LED light (3c) flashes, as this indicates a low battery
level.

STREET MODE ACTIVATION:
RACE MODE ACTIVATION:
Should the System detect a situation incompatible with the normal
expected usage of the System, the System will automatically turn off and
so will the Led Display (3). Open and close the Front Flap (2) to turn the
System on again and re- perform the System Check.
When the System Check has been correctly
performed, and the yellow light turns off, the
System must detect a riding condition for at least
10 seconds in order to be ready to deploy in case of
an accident.
When Race Mode is selected, after the completion
of the System Check, the LED Display will show solid
green and yellow LED light. The yellow light will turn
off only when rider reaches 100km/h (62mph) and
only then the System will be ready to deploy. If the
rider stops or the speed drops under the 100km/h
for an extended period of time, the System will
return in the System Check phase (indicated by the
solid yellow and green LEDs – see Section 13 below).

c) Turning Off
Turn the System off by opening the Front Flap (2). The System will shut down after 1 second
approximatively. Confirm that the System is off by checking that there are no indicator
lights illuminated in the LED Display (3).
To keep the System turned off, keep the Front Flap (2) open and make sure that Magnetic
Zip Closure (1) stays unzipped, as shown in Figure 9. Always keep the System in this condition
while stored, transported or shipped.

ALWAYS turn the System off [by opening the Front Flap (2)] when you
are not riding a motorcycle, even if you continue to wear the System.
Although the System has been evaluated for a number of non-riding
activities, keeping the System turned on and/or active increases the
possibility of an unwanted deployment and drains the battery.
When not in use and being stored, transported or shipped, the System
must be turned off by leaving the Front Flap (2) open. This prevents
System to accidentally turning on and inadvertently deploying, and it
will preserve battery and battery life.
In Street Mode, you MUST ALWAYS check the LED Display (3) after
the System Check to confirm you have the solid green (3a) LED
illuminated before starting to ride/use the Tech-Air®5 System. The
System will not deploy if a solid green LED (3a) is not present on LED
display (3).
WARNING!
WARNING!
WARNING!
The status of the Tech-Air®System can be checked by connecting the System
through the Tech-Air®App. When the System Check has been successfully
passed and the System is active, the Tech-Air®App will display the indication
“System On”.
System inactivation can also be “forced” directly using the App. This
functionality can be useful in case the user wants to turn off the airbag
protection, for instance before undertaking some heavy off-road riding
[please note that the System cannot be turned on again by means of the App.
To do so, open and close the Front Flap (2)].
IMPORTANT!
IMPORTANT!
The Front Flap (2) functions using magnets. Magnetically sensitive items
(such as credit cards) should be kept at least 1cm away from the switch area.
Even when the System Check has successfully been completed, the System
will automatically turn off should the System detect:
- a rider position incompatible with the normal wearing of the System
or
- no movements for more than 10 minutes. When either of the above
situations occur, open and close the Front Flap (2) to restart the System
and perform a new System Check (for further details on the System Check
activity, please check above paragraph 12 b))
Always check that the appropriate riding mode is selected either
by means of the Tech-Air®App and/or checking the LED Display (3)

14. Cleaning, Storage and Transportation
Vest Cleaning
Use only a cloth dampened with water to clean the vest (fabric and plastic parts). Solvents or
chemical cleaners must not be used, as they may compromise the integrity of the System.
19 EN
Any LED indication different from the solid green LED (3a) indicates
that the System is not active and accordingly will NOT deploy in a
crash.
Under NO circumstances should the vest be washed in a washing
machine, submerged in water, tumble dried or ironed. This may cause
permanent damage to the System and cause malfunction.
Do NOT leave the System in direct sunlight inside a closed car or
otherwise exposed to high temperatures. High temperatures will
damage the battery and possibly the other electronics of the unit.
The System’s storage temperature must be between -20°C and +60°C
(-4°F to 140°F). Exposure to a temperature lower than -20°C (-4°F)
may cause permanent damages to the battery.
Zipping up the vest and closing the Front Flap (2) will cause the
System to turn on. To prevent this, it is essential that the Front
Flap (2) is opened, in order to prevent accidental activations of the
System. Failure to do so will cause the System to turn on, which will
cause the battery to drain. When storing the System remember to
keep the Front Flap (2) open and check that there are no indicator
lights illuminated on the LED Display (3).
WARNING!
WARNING!
WARNING!

WARNING!
Indications during battery charging
During battery charging the LED Display (3) will show a continuous flashing. When the
battery is fully charged all 3 LEDs will remain illuminated.
Storage
When not in use it is recommended to store the System in its original packaging. It may
be stored flat provided that no heavy or sharp objects are placed on top of it. The System
can also be stored hung up from a rail. It should always be stored in a cool, dry place, out
of direct sunlight.
The battery of the System slowly self-discharges, even if the System is not turned on, in
particular if the System is stored in a warm environment. It is thus recommended that even
whilst in storage the System be periodically recharged (at least once every 18 months) to
prevent battery drainage and shortening the battery life.
Transportation
Users should be aware that airbag inflators are pyrotechnic devices. Under the European
pyrotechnic Directive (2007/23/EC) they are certified safe for transportation, including by
air, provided that the System is checked into the aircraft’s hold as checked luggage.
When transporting the System by air, users are strongly recommended to download and
print a copy of the Product Information Sheet (PIS) in case they are questioned by airport
staff. This can be downloaded from the Tech-Air®App (Section 17).
Note: Not all countries worldwide permit the import of pyrotechnic devices. Prior to
traveling, users should check with the appropriate authorities of countries through which
and to which they are traveling to determine if the System will be permitted entry or not.
As part of the recommended two-yearly service the System will be
disassembled and washed.
Tip:
Product Information Sheet (PIS) can be downloaded using the Tech-Air®App.
IMPORTANT!
IMPORTANT!
The solid green LED (3a) indicates that the System is on.
If the battery becomes fully drained, the System may require a longer
time to recharge. It is thus recommended that the System is periodically
recharged as indicated.

15. Maintenance, Servicing and Disposal
Garments with electronically activated airbags are critical safety systems which must be
maintained in good working order to ensure their correct function. If not, they may not
function properly or at all.
Maintenance
Prior to each use, the user should conduct a check of the System, looking for any signs of
wear (loose threads, holes, marks) or damage. If any signs of wear are found, the System
should be inspected further by an authorized Alpinestars Tech-Air®Service Center.
Servicing
Alpinestars recommends that the System be routinely serviced at least every 2 years or
after 500 hours of functioning by Alpinestars or an authorized Alpinestars Tech-Air®Service
Center. During the routine service the airbag and the unit’s components will be inspected.
Routine can be requested directly at an Alpinestars Tech-Air®Dealer. The following work is
undertaken as part of the routine service:
• All components are removed from the System and the vest is washed.
• The diagnostics of the electronic unit are checked (and firmware upgraded, if applicable).
• The airbag is inspected for any sign of wear and/or damage.
• The System is reassembled into the vest and checked functionally.
Disposal of the System at the end of life span
Deployed System
An adequate waste disposal System allows for a correct and environmentally-friendly
recycling, processing and disposal of the System itself, thus avoiding the dispersion of
dangerous substances and any negative effects on the environment and health and favoring
the reuse and/or recycle of the materials which the System is made of. The unauthorized
disposal of the System on behalf of the user, entails application of fines pursuant to the
current law. We urge you to check the current legislation and the measures adopted by the
public services operating in your territory.
20 EN
Two years or 500 hours of functioning is the maximum recommended
period between inspections.
Tip:
If no service or recharge operation has been conducted after two
years or 500 hours of functioning from the purchase date, there is
the possibility that the System will not function inside the Envelope
of Protection.
There are NO user serviceable parts inside the System. Under no
circumstances should users attempt to open, service, disassemble or
modify the System. Do not remove or change the internal battery. Any
and all work performed on the System must be done by Alpinestars
or an authorized Alpinestars Tech-Air®Service Center. Severe injury
or damage may result otherwise.
WARNING!
WARNING!
A deployed airbag can be confirmed by turning on the System and looking
for the red LED (3c) on the LED Display (3) (Section 13) or checking the
System status using the Tech-Air®App (Section 17).
Tip:
IMPORTANT!
IMPORTANT!
IMPORTANT!
The access zip to the airbag is partially sealed. Cutting these Warranty Seals
(5) voids the warranty on the product.
The access zip to the airbag is partially sealed. Cutting these Warranty Seals
(5) voids the warranty on the product.
The System contains electronic components, accordingly, at the end of its
working life, the System must be disposed following the European Directive
2012/19/EU requirements. The symbol of the crossed bin displayed on the
System indicates the electronic parts of the System which, at the end of
its life span, must be separately disposed from other waste, for appropriate
waste processing and recycling. The user must therefore take the Electronic
Unit (8), Magnetic Cable (12) and all other electronic parts marked with
the crossed bin, to those sites assigned for the disposal of electrical and
electronic waste or return the System to an Alpinestars Tech-Air®Dealer for
disposal in accordance with the local waste requirements.

Undeployed System
21 EN
Alpinestars is not responsible for reporting possible accidents or
for providing any assistance to those involved. User agrees that
Alpinestars has no duty or responsibility to report any accidents
or the possibility of any accidents based on the data transmitted
to Alpinestars. Users assumes the risk of any accidents or injuries
whether or not data is being transmitted to Alpinestars.
An undeployed System still contains live pyrotechnic charges and
thus must NOT be disposed of in household waste or incinerated.
WARNING!
WARNING!
Undeployed System must be returned to an Alpinestars Tech-Air®Dealer for subsequent
return to Alpinestars who will handle the disposal. This service is free of charge.
16. Actions in the Event of an Accident
Whenever the System deploys, a service must be undertaken by an authorized Alpinestars
Tech-Air®Service Center that will check the status of the System and consequently advise
on the type of service needed.
The Tech-Air® 5 System features an airbag that is certified for upto three-inflations, meaning
that after a deployment, and when the System is received for service, the authorized
Alpinestars Tech-Air®Service Center will perform an inflation test of the airbag to check if
the airbag was damaged during the deployment.
a. If such inflation test is passed, the airbag was not damaged during the deployment and
accordingly the service will involve the replacement of the gas inflators only.
b. If such inflation test is not passed, the airbag was damaged during the deployment and
accordingly the System will undergo a full service that will involve the replacement of the
gas inflators and the airbag.
At the third deployment, the System must undergo a full service as indicated in point b. above.
17. Tech-Air®App
Tech-Air®5 System is equipped with a Bluetooth Low Energy (BLE) device which allows to
directly connect the user’s mobile phone to the System, in order to get certain information
from the System and have access to several functions, such as:
- monitor the status of the System;
- verify the installed software and, eventually, perform the latest software updates;
- send feedback related to the System and its performances;
- and many others.
The Tech-Air®App is available for download in the Android Play Store and in the Apple Store.
The user can notify any feedback related to deployment events to Alpinestars
through Tech-Air®App and/or contacting Tech-Air®Support (see Section 19).
IMPORTANT!
IMPORTANT!
Tech-Air®5 Electronic Control Unit registers the number of deployments.
After the third deployment, the System will indicate permanently a System
Fault (steady red light on LED Display (3)). The System will remain blocked
until a full service is performed by a Tech-Air®Authorized Service Center.
Tech-Air®App is not necessary for Tech-Air®5 System to work as an impact
protector. Tech-Air®5 System will protect the user as described in sections
2 to 13 even if Tech-Air®App is not installed or not running on the user’s
mobile phone.
Accident WITHOUT Deployment
In the case of minor, low energy and/or low speed accidents, such as those involving speeds
below those described in Section 3 (“Tech-Air®Envelope of Protection”) it is likely that the
System will not deploy. Nonetheless, a thorough inspection of the System should be made
to ensure that there is no significant damage (tears, holes, etc.) which could compromise
the function of the System, as per the maintenance check outlined in Section 15.
In case of situations where the user believes the System should have deployed, a feedback
can be sent to Alpinestars through the Tech-Air®App and/or contacting Tech-Air®Support.
If the System is returned to an Alpinestars Tech-Air®Service Center for an inspection, a
detailed description of the event (including photos where possible) must be included.
In case of deployment in situation where the user believes the System should not have
deployed, the System should be returned to an Alpinestars Tech-Air®Dealer along with a
detailed report of the event (including photos, if possible).

User Registration
To have access to the Tech-Air®App, the user must log in or, if not, sign up. In order to configure
the Tech-Air®App Bluetooth must be turned on within the user’s mobile phone.
Monitoring the System Status
The App provides information about the actual operating mode of the System, verifying if
the System is functioning correctly or not. The indication “System On” displayed on the screen
indicates that the System Check has been successfully passed and that the System is active.
Pair the System
Once the Bluetooth is turned on, the App will automatically attempt to establish a connection
with an available Tech-Air®5 System, if already paired with the System. Should no Tech-Air®
System have been already paired to the App, the System can be easily paired to the App by
scanning the QR code present inside the System’s internal neck liner. Once the System has been
correctly paired the App, it will be possible to visualize the overall status of the System, such as
battery level and installed software, and enabling or disabling some of the functions provided
by the App. When the Tech-Air®5 System turns off, the Bluetooth®connection will stay active
to allow the dialogue between the System and the mobile phone, provided that the System is in
the vicinity. In this case, the active connection with the App is indicated by the blinking yellow
light (3b) on the LED display (3) and the User can interact with the App. The LED display will
definitively turn off when the System doesn’t detect any connection with the App.
