Congratulations on your choice of CYPRES, the
surely safest and most accurate AAD currently
available.
Like most skydivers, you probably assume you
will always have time to deploy your reserve
canopy yourself, and that situations requiring use
of an automatic activation device always happen
to others. We do hope you will never have such
trouble, and that your CYPRES will never have to
take action to save your life.
Should CYPRES ever decide to activate your
reserve, it will most likely happen at a moment
which, no matter how experienced and cautious
you are, justies that you haven‘t left your safety
to chance.

The Smoke Jumper CYPRES 2 is an Automatic
Activation Device for parachutes, which is built
for the needs of Smoke Jumper activities.
It initiates the reserve deployment sequence; if the
Smoke Jumper should still have a vertical speed
of more than 35 meters per second (78 mph) at
approximately 1200 ft AGL assuming the arming
handle was pulled at 3000 ft AGL.
The Smoke Jumper CYPRES 2 does its job by
severing the reserve closing loop allowing the
spring loaded pilotchute in the reserve container
to push away the aps of the container and to
jump out into the slipstream and initiate the re-
serve opening.
What a Smoke Jumper CYPRES 2 is

1. Function
1.1 How CYPRES works
The processing unit contains a factory-pro-
grammed microprocessor that is capable of real-
time calculations of the jumper‘s altitude and rate
of descent based on barometric pressure.
By monitoring this data, certain criteria are gener-
ated from which conclusions are drawn. Should
the conclusion be that the jumper is in a danger-
ous situation (i.e. still in freefall at a low altitude)
the processing unit triggers the release unit which
initiates the reserve deployment sequence.
The release unit (cutter) system for the reserve
container is completely independent of the rig‘s
primary system, because it does not pull the rip-
cord pin out of the closing loop, but rather cuts
the loop inside the reserve container to release the
pilot chute.
Initiating the reserve deployment sequence by
cutting the loop is a method invented and patented
by the founder of Airtec, Helmut Cloth, in 1987.
The CYPRES‘ activation system has these advan-
tages:
• The deployment sequence of the reserve para-
chute can be initiated in two different ways.
One method is by the jumper pulling the re-
serve release handle. The other method is used
by CYPRES
it automatically cuts the closing
loop.
• Mechanical components are reduced to a sin-
gle movable piston in the release unit.
• The activation system is located inside the re-
serve container where it is not exposed to ex-
cessive shock or other adverse inuences.
• The system is unobtrusive and can be installed
so that it is undetectable from the outside.

page 6 - Smoke Jumper CYPRES 2 User’s Guide -
The distance which the piston moves in case of an
activation is approx. 5 mm.
The release unit (cutter) is a unique design specif-
ically developed for CYPRES. Features include
a completely self-contained enclosure to avoid
expelling anything during activation.
During an 18 month long investigation by BAM
(Bundesanstalt für Materialprüfung), Berlin, 99
release units were tested. The result is that BAM
and the U.S. DOT have classied the CYPRES as
being non-hazardous.
Due to its high reliability and other properties, the
CYPRES release unit is currently being used in
aerospace applications (satellites).
• The system is unobtrusive and can be installed
so that it is undetectable from the outside.

1.2 Components
CYPRES consists of a control unit, a processing
unit and one release unit (cutter) for 1-pin reserve
container or two release units (cutters) for 2-pin
reserve container.

1.3 Power supply
No attention is needed to the power supply of
Smoke Jumper CYPRES 2.
The unit is designed to function from the date
of manufacture until the rst maintenance, from
the rst maintenance to the second maintenance,
and from the second maintenance until the end of
warranty time without limitations concerning the
number of jumps. If a Smoke Jumper CYPRES 2
should cease to function due to a faulty power
supply prior to the maintenance due date, Airtec
will take care of this with the highest priority.

The push button on the control unit should be
pressed with the ngertip alone; please do not use
a ngernail or any object. Use a short clicking ac-
tion in the middle of the button. You should fa-
miliarize yourself with switching Smoke Jumper
CYPRES 2 on to be able to do the functioning
test.
With this Smoke Jumper CYPRES 2, you can use
the control unit only to check the operativeness.
Nothing else.
Do the operativeness check prior to every rst
jump of a day.
2. How to handle the Smoke Jumper CYPRES 2
2.1 How to deal with the control unit
The functioning test of the Smoke Jumper
CYPRES 2 is initiated by pressing the push but-
ton four times with very short clicks. Start the
switch-on cycle by clicking the button once. After
approx. one second, the red LED-light will glow.
You must acknowledge the red light immedi-
ately by clicking the button again. This sequence
- a click following appearance of the red light -
will be repeated two more times. After a total of
four clicks, Smoke Jumper CYPRES 2 goes into
self-test mode. If you do not act promptly after
seeing the LEDlight, or if you push the button to
soon, Smoke Jumper CYPRES 2 will ignore the

page 10 - Smoke Jumper CYPRES 2 User’s Guide -
switch-on attempt. This four-click initiation cycle
has been designed to avoid accidental switch-on.
Once the switch-on procedure is nished, the unit
will run through its self-test. Initially, the display
will show the number „10“, and then a countdown
ending in „0“.
Between „2“ an „0“ the unit will interrupt and
show the actual airpressure in hPa (that is equiva-
lent to millibars). It will be a value between 700
and 1050.
HPa is the scale the Smoke Jumper CYPRES 2
works with.
When you see the „0“ at the end of the selftest
then the functioning test has successfully nished
and the display will go blank again, stating that
the unit is ready for work.
2.2 How to check the operativeness
Perform a switch on procedure (see chapter 2.1)
whereupon automatically the selftest will be car-
ried out.
The selftest ends showing a 0 on the display for 1
second and then the display goes blank.
After this procedure the unit has shown its opera-
tiveness.
Conduct this operativeness check prior to every
rst jump of a day.

- Smoke Jumper CYPRES 2 User’s Guide - page 11
2.3 How to handle in practical use
Aside the operativeness check prior to the rst
jump of the day the sole action required for the
Smoke Jumper CYPRES 2 is only necessary on
the jumprun. Prior to exit, a handle on the main lift
web must be separated from its velcro and pulled
downward for at least 10 centimetres. (To conrm
this action a “0” will be displayed in the control
unit window) The Smoke Jumper CYPRES 2
will now initiate the active mode and monitors
the situation. If it detects that the Smoke Jumper
has left the plane and has fallen to approximately
1.200 feet AGL with a vertical speed higher than
35 meters per second (that is 78 mph), then it will
cut the reserve containers closing loop to initiate
the deployment sequence. The Smoke Jumper
CYPRES 2 will initiate the deployment sequence
of the reserve container even lower, down to ap-
proximately 400 feet AGL, if the vertical speed
has not exceeded 35 meters per second at 1.200
feet AGL, but only later. These calculations as-
sume that the the arming handle was pulled at ap-
proximately 3.000 feet above ground.
Activation window
· Arm the unit on jumprun at approx.
3.000 feet AGL
· Activation window starts at approx.
minus 1.800 feet from jumprun
· Activation window ends at approx.
minus 2.600 feet from jumprun
If the arming handle is pulled at another height
above ground: the activation should happen at ap-
prox. 1.800 to approx. 2.600 feet below this spe-
cic arming altitude if the activation conditions
are given.
Once the handle has been pulled the unit is in ac-
tive mode right away.

page 12 - Smoke Jumper CYPRES 2 User’s Guide -
In short words:
· the activation handle has to be in its
original position when you enter the
plane
· on the jumprun, prior to exit, it has
to be pulled downwards some centi-
meters
· it has to be put back into its origi-
nal position after the jump, at least
prior to the next boarding.
At any time it is possible to put the unit manu-
ally back into ‘sleep mode’ by bringing back the
handle into its original position. The unit is now
in ‘sleep mode’, when the arming cable is gently
pushed into the Smoke Jumper CYPRES 2 and
physically stops. To achieve ‘sleep mode’ it is
mandatory to push the cable this far.
The unit will automatically go back into sleep
mode two hours after the active mode was initi-
ated or after a height loss of approx. 2.600 ft from
arming elevation, even without touching the han-
dle.
On packing your parachute after a training jump
or a mission, bring the handle back into its origi-
nal position. This is mandatory because only by
„pulling the activation handle some centimeters
downwards from its original position“ will allow
the Smoke Jumper CYPRES 2 to change between
‘sleep mode’ and active mode. This allows the
unit to monitor what is going on and being ready
to do its job.

3. Access to unit information
The Smoke Jumper CYPRES 2 provides an easy
way to view
1. the activation counter,
2. the units serial number,
3. the next maintenance date*
When the 0

appears at the end of the switch-on
procedure press the button immediately and keep
it pressed.
Each value is displayed for 5 seconds, then the
next value shows up.
You can stop the information sequence whenever
you want by just letting go of the button.
* After the 8 year maintenance has been per-
formed, the words ‘maint. no’ and the date of the
total lifetime (end of life) is shown.

4. Changing the release unit(s)
After an activation the release unit can be changed
by your rigger packer via the plug-and-socket
connection.
Disconnecting the release unit:
Hold plug and socket by their aluminium grips
and pull them apart using a smooth straight mo-
tion. Do not twist!
Connecting the release unit(s):
Hold plug and socket by their aluminium grips.
Place the plug directly in front of the socket and
connect them by pushing together with a smooth
straight motion until it is completely seated.
Do not twist!
It is easy to change a 1-pin CYPRES to a 2-pin or
CYPRES or vice-versa, by swapping cutter types.
1-pin Cutter 2-pin Cutter

Notes:
1. CYPRES 1 eld replaceable cutters (no alumi-
num grip) can be used with CYPRES 2. (CY-
PRES 2 is equivalent to Smoke Jumper CYPRS
2 concerning the release units.) They will func-
tion properly.
CYPRES 2 cutters (identied by aluminum
grip) can be used with any CYPRES 1 with the
eld replaceable cutter connector. They func-
tion properly.
2. Release units (cutters) are numbered via a heat
shrink tubing placed on the cable. This number
identies the cutter. A table of cutter numbers with
corresponding dates of manufacture are available
at www.cypres.cc
3. It is possible that the cutter plug could separate
from the socket after a CYPRES activation. In
the rare combination of this and a water landing,
the socket must be dried out before further use.
Do that by tapping the open end of the socket
at onto a at surface such as a table top. Once
no additional water comes out while tapping on
WARNING! Do not use release units
(cutters) after the Lifetime Warranty
period.
Release units (cutters) also require
technical service (maintenance) ev-
ery four years.
Please send cutters more than four
years old, that have not been attached
to a CYPRES during maintenance to
Airtec or SSK for a free no-charge in-
spection prior to use.
the table top, store the CYPRES with the open
end of the socket hanging downward for another
24 hours in a dry area, to allow the socket to dry
out completely. When completely dry, insert the
plug of the new cutter.
4. Use a one-pin cutter in a one-pin container and
a two-pin cutter in a two-pin container.

page 16 - Smoke Jumper CYPRES 2 User’s Guide -
5. Water contact
Because of the cable housing for the arming cable,
the Smoke Jumper CYPRES 2 is not waterproof.
If a Smoke Jumper CYPRES 2 came in contact
with water, please send it in for a free inspection.
6. Important notes for users
• CYPRES is shielded against radio-transmitter
signals. Extreme concerted efforts have been
taken to protect the Smoke Jumper CYPRES 2
from „radio pollution“. Although the extraor-
dinary shielding system of the Smoke Jumper
CYPRES 2 has been investigated thoroughly,
it is impossible to have 100% pro-tection. It is
still recommended to avoid strong radio-trans-
mitters. Please contact Airtec if you have ques-
tions.
• A release unit that has activated builds up a
high internal pressure and will remain pres-
surized. Never attempt to open it by force. It
can, however, be stored safely for an indenite
period of time, provided that it has not been
damaged.
• To achieve ‘sleep mode’, the arming handle
needs to be pushed gently into the Smoke
Jumper CYPRES 2 until it physically stops.

- Smoke Jumper CYPRES 2 User’s Guide - page 17
7. Error Display
If any irregularities are detected during selftest, the
Aircrew CYPRES 2 shows a number on the dis-
play. The error code is displayed until the unit is
switched off manually or by the automatic shut off
after 14 hours running-time. During error display
the arming cable is out of function.

One or both of the attached release units are
not correctly electrically connected to the
unit. The reason may be a cable break, the
cutter plug could be disconnected, or the re-
lease unit(s) may have activated.

Excessive variations in ambient air pressure
have been measured during the self-test pe-
riod. The unit is unable to obtain consistent
values for the ambient air pressure at ground
level. Possible reasons could be that an at-
tempt to switch CYPRES on has been made
in a car driving uphill or downhill, in an el-
evator or in a ying aircraft.
The switch-on procedure can be performed several
times after a „3333“ error was displayed. If the 0

the unit will display the error code again and then
switches off. Please discontinue use and send the
unit in for service.
If other error codes appear in the display, if the unit
switches itself off and can not be switched on again,
if the unit does not switch off after 14 hours, if there
is no red light when the button is pressed, or if any-
thing else unusual occurs please record the error
code and contact Airtec or SSK before further use!
Every technical device can fail. So everything imag-
inable can happen with the CYPRES, including, but
not limited to: displaying a status which is not true,
failing to function, or functioning at a wrong mo-
ment or at a wrong occasion. If you or your friends
or family are not willing to accept these uncertain-
ties and risks, then please don’t use CYPRES.

8. Installation
The original smoke jumper harness and container
was investigated by Airtec a number of years ago.
The positioning of all components was dened
and tested.
The new smoke jumper harness and container,
designed by the Relative Workshop in the end of
2003 was also investigated by Airtec. The posi-
tioning of all components was dened in coopera-
tion with the Relative Workshop and tested.
Under no conditions are deviations from these in-
structions allowed.
Control unit cable and cutter cable must be placed
without tension. Excess cable is stowed in the at
part of the pocket underneath the velcro-adjust-
able ap. If you have to stow both the thinner cut-
ter cable and the thicker control unit cable, be sure
to place the thicker cable so that it lays on top of
the thinner one. Cables should be placed in a cir-
cle in order to avoid twists. Always avoid pulling,
bending, twisting or kinking the cables.

9. Technical service
The extremely reliable function of CYPRES is
based on 4 facts: exclusive use of carefully pre-
treated and approved parts, strict detailed manu-
facturing procedures, continuous quality control
and monitoring through the manufacturing pro-
cess, and regular periodic technical service (main-
tenance). 4 and 8 years after the original date of
manufacture, maintenance procedures according
to the manufacturers guidelines are necessary.
There are 4 primary reasons for the maintenance:
1. Deviations between nominal and actual values
are corrected to ideal values. Every detail is
observed. It is common that signs of wear and
tear are corrected and sometimes even ‘cos-
metic’ treatment is done.
2. The technical condition of each unit is ana-
lyzed. The fact that a very high percentage of
units are returned for the periodic maintenance
gives the ability to see statistical trends and
to predict potential problems at a very early
stage. The advantage: often it’s possible to
prevent situations by modications during the
maintenance procedures, rather than having to
x problems with downtime later.
3. Experience shows that during a period of 4
years, changes and improvements do hap-
pen. Applicable updates are performed dur-
ing maintenance. Such updates may have the
background of technical improvements, or en-
hancement of knowledge, or may result from
environmental changes or changes in the sport
(e.g. new disciplines), which Airtec is always
researching and taking into consideration.
4. The most important part of the maintenance is
the individual pre-adjustment of each unit for
the next 4 years. A unit will not be returned be-
fore a high condence level is reached regard-
ing the prediction of the unit’s proper function
for the next 4 years.

page 20 - Smoke Jumper CYPRES 2 User’s Guide -
At any time it’s possible to check the date of the
next maintenance. (See chapter 3)
If the unit enters 6 months before maintenance
due date, the maintenance
date (next maint. in month
/ year) will automatically
be shown at each selftest.
6 months after the due date
the display will change to:
‘next maint. now’.
All displayed dates are only a reminder.
Please choose a suitable date during the 13 month
time frame for a convenient performance of the
maintenance. According to experience, the num-
ber of maintenances and the necessary time to do
them increases February-May. For quicker ser-
vice, a date between June and January is a better
choice.
The maintenance has to be performed 4 and 8
years after the original date of manufacture. The
earliest possible date for the CYPRES 2 mainte-
nance is 6 months early, the latest 6 months after
the month of manufacture.
A delayed maintenance has no advantage. It does
not save any cost as the Lifetime Warranty re-
mains the same. It’s smart to choose a suitable
time during the 13 month window for sending the
unit in for maintenance, rather than waiting until
the last possible moment, or until the beginning of
the next season.
Because of the 134,000+ maintenance proce-
dures performed to date on CYPRES, and lots
of improvements incorporated into the design of
CYPRES 2, Airtec has determined that it is pos-
sible to extend the maintenance window to 13
months on
CYPRES 2. This maintenance window
gives you more freedom, and avoids maintenance
down-time at the wrong time of the year - please
use this new feature wisely!
