Congratulations on your choice of CYPRES, the
safest and most accurate AAD currently available.
Like most skydivers, you probably assume you
will always have time to deploy your reserve can-
opy yourself, and that situations requiring the 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
try to save your life.
Should CYPRES ever decide to cut your reserve
closing loop, it will most likely happen at a mo-
ment which, no matter how experienced and cau-
tious 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 reserve opening.
What a Smoke Jumper CYPRES 2 is
CYPRES is not able to open your reserve. It is only
intended to sever your reserve closing loop. CYPRES
is strictly a backup device and does not replace proper
training or timely execution of emergency procedures.
It may display a wrong status, fail whenever and for
whatever reason and may cause injury or death. If you
are not comfortable with these risks you must not use
CYPRES. You must make sure that the loop passes
through the cutter’s passing hole. If you loan, rent or
sell your CYPRES to somebody it is your responsibility
to inform him about the above circumstances.

1. Function
1.1 How CYPRES works
The processing unit contains a factory programmed
microprocessor that is capable of real-time calcu-
lations 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 dangerous situ-
ation (i.e. still in freefall at a low altitude) the pro-
cessing unit triggers the release unit to initiate the
reserve container opening sequence.
The release unit (cutter) system for the reserve con-
tainer is completely independent of the rig‘s primary
system, because it does not pull the ripcord pin out
of the closing loop, but rather cuts the loop inside the
reserve container to initiate the opening sequence.
The reserve closing loop has to pass through the cut-
ters passing hole.
Initiating the opening sequence of a reserve con-
tainer 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 reserve container opening sequence can be
initiated in two different ways. One method is by
the jumper manually pulling the reserve release
handle. The other method is by CYPRES when it
automatically cuts the closing loop.
• Mechanical components are reduced to a single
movable piston in the release unit.
• The activation system is located inside the re-
serve container where it is not exposed to exces-
sive shock or other adverse inuences.
• The system is unobtrusive and can be installed
so that it is undetectable from the outside.

- Smoke Jumper CYPRES 2 User’s Guide - page 5
The distance which the piston moves in case of
an activation is approx. 5 mm.
The release unit (cutter) is a unique design speci -
cally developed for CYPRES. Features include a
completely self-contained enclosure to avoid ex-
pelling 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).

1.3 Power supply
No user attention should be needed for the power
supply of CYPRES 2.
The unit should function from the date of manu-
facture (DOM) to the end of service life.
If CYPRES 2 should cease to function contact
Airtec or SSK.
No CYPRES 2 user has ever spent any money on
battery since 2003.

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

- Smoke Jumper CYPRES 2 User’s Guide - page 9
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.

page 10 - Smoke Jumper CYPRES 2 User’s Guide -
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.

- Smoke Jumper CYPRES 2 User’s Guide - page 11
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 Jumpger 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 10 year maintenance has been per-
formed, the words ‘maint. no’ and the date of the
total lifetime (end of life) is shown.

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
CYPRES or vice-versa, by swapping cutter types.
1-pin Cutter 2-pin Cutter
4. Changing the release unit(s)
After an activation the release unit can be changed
by any 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!

page 14 - Smoke Jumper CYPRES 2 User’s Guide -
Notes:
1. CYPRES 1 eld replaceable cutters (no alumi-
num grip) can be used with CYPRES 2 They
will function properly, however this combina-
tion is not water-resistant.
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 - but this combination is not wa-
ter-resistant.
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
the table top, store the CYPRES with the open
end of the socket hanging downward for an-
other 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.
Do not use release units (cutters) after the end of cutter
service life (16,5 years after DOM)
Used release units (cutters) that are / were attached to
a CYPRES unit are also subject to a technical service /
maintenance. See chapter 9.
New release units (cutters) that were never attached
to a CYPRES unit and were stored (according to
manufacturers instructions) do NOT need to be sent in
for maintenance within the service time frame.

- Smoke Jumper CYPRES 2 User’s Guide - page 15
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.

page 16 - Smoke Jumper CYPRES 2 User’s Guide -
7. Error Display
If there is an error condition detected during the
self-test countdown, CYPRES 2 shows an error
code on the display.
or One or both of the attached re-
lease units are not correctly electrically connected
to the unit. The reason may be a cable break, the
cutter plug could be disconnected, or the release
unit(s) may have activated. Check / replace the
release unit(s).
Excessive variations in ambient air pres-
sure 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. Pos-
sible reasons could be that an attempt to switch
CYPRES on has been made in a car driving uphill
or downhill, in an elevator or in a ying aircraft.
The switch-on procedure can be performed sev-
eral times after a error was displayed.
If is displayed, the unit has successfully
gone through the self-test.
Codes 1-3 are displayed for approx. 2 seconds, then
unit switches itself OFF. (Display goes blank).
unit reached last month of the total service
life, displayed for approx. 5 seconds, unit remains ON
low battery condition. Please
contact Airtec or SSK prior to next use.
After one of the following three error codes
appears, the unit switches OFF and can-
not be switched on again. Please discon-
tinue use and send the unit in for service.
Power Down
Checksum Error
Pressure Sensor Error
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 anything else unusual occurs please record the
error code and contact Airtec or SSK before further
use!
Malfunction: A malfunction can easily injure or kill you
or others. Every technical device can fail. So everything
imaginable 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 moment or at a wrong
occasion.
If you or your friends or family are not willing to accept these
uncertainties and risks, then you must not use CYPRES.

- Smoke Jumper CYPRES 2 User’s Guide - page 17
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.

page 18 - Smoke Jumper CYPRES 2 User’s Guide -
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). We offer a maintenance for 4 primary
reasons:
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 a
maintenance cyle (4 or 5 years), changes and
improvements do happen. Applicable updates
are performed during maintenance. Such up-
dates may have the background of technical
improvements, or enhancement 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 cycle. 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 cycle.
Reliability: As NOTHING lasts forever, the longer you
use a device without a thorough check, the greater
the chance that it does not work properly every time
you need it. If you choose to not have maintenance
performed on your device you’re taking the risk that the
reliability level will decrease.
Return your CYPRES 2 for maintenance (see chapter
12.1 for utilization cycle).

- Smoke Jumper CYPRES 2 User’s Guide - page 19
For maintenance cycle schedule see chapter 12.1
The earliest possible date for the CYPRES 2 main-
tenance is 6 months early, the latest 6 months after
the month of manufacture. This maintenance win-
dow gives you more freedom, and avoids main-
tenance down-time at the wrong time of the year.
It’s smart to choose a suitable time during the 13
month window for sending the unit in for mainte-
nance, rather than waiting until the last possible
moment, or until the beginning of the next season.
Reaching the end of the rst
maintenance cycle your
CYPRES will start to tell you
that there is a maintenance
possible in six month from
then and the unit will display
the proposed month and year.
That will happen after switch on in the self test
between the unit showing and .
From there on you have one year to give it to us
and be in the maintenance window.
If you don`t do it until the proposed date, then the
unit will show month and year for a little bit lon-
ger then it did before.
Three month after the proposed date it will show
month and year for an even longer time.
However, after this remembering your unit will
always proceed and will go to and be us-
able for you.
If we receive your unit from exactly 6 month be-
fore the proposed date until six month after the
proposed date (that means in the maintenance
window) in our place for a maintenance, we will
execute the procedure with all the details and con-
sequences as described in this manual. The price
for this treatment will be the CYPRES mainte-
nance at rate, even when a unit requires exten-
sive repairs.
If you want us to do the maintenance, we really
ask you to please give us your CYPRES in the
meaningful time span. And not earlier and not
later.
In case we receive your unit in our place outside
of this time window we will possibly still be will-
ing to execute a treatment, but the details and the
consequences will likely be different and the price
will be signicantly higher.
