1. Function
1.1 How the Time CYPRES 2 works
The „Time“ CYPRES 2 activates time related.
Once the arming cable is pulled, the unit starts
counting seconds and activates the cutter after the
previously programmed delay time. The activation
is solely time related and is completely independent
of any vertical descent rates.
Any delay time between 0 and 999 seconds can
be programmed.
The release unit (cutter) system for the parachute
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 parachute container to release
the pilot chute.
Opening a parachute container by severing the
closing loop is a method invented and patented
by the founder of Airtec, Helmut Cloth, in 1987.
The CYPRES‘ parachute activation system has
these advantages:
• The reserve container opening sequence can be
initiatedintwodierentways.Onemethodis
by the jumper manually pulling the reserve re-
lease 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reserve
container where it is not exposed to excessive
shockorotheradverseinuences.
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.

page 4 - Time 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speci-
cally 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).

1.3 Power supply
You do not need to worry about CYPRES 2’s power
supply in any way.
The unit should function from the date of manufac-
ture(DOM)untiltheendofitsservicelife.
If CYPRES 2 ceases to function or displays an
error code during the self-test please contact Airtec
or SSK.
No CYPRES 2 user has ever had to pay for a battery
since 2003, provided that the maintenance
intervals have been adhered to.

2. How to handle the Time CYPRES 2
Always check the operativeness of the Time
CYPRES 2 prior to the rst action of the day:
Perform a selftest. Do it on the ground before boarding.
SAFETY INSTRUCTIONS
2.1 Switching on
CYPRES is switched on by pressing the push
button 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 immediately
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, CYPRES goes into self-test mode.
If you do not act promptly after seeing the LED-
light, or if you push the button to soon, CYPRES
will ignore the switch-on attempt.
This four-click initiation cycle has been designed
to avoid accidental switch-on.
Once the switch-on procedure is finished, the
unit will run through its self-test. Initially, the
display will show the number , and then a
countdown ending in . After the
display shows the previously programmed delay
time, for example , which means 15 sec-
onds from arming cable pull until activation. The
programmed delay time stays in the display for
maximal 14 hours. If the arming cable is pulled,
wait!

the display starts to countdown, the unit activates
when zero is reached.
After 14 hours without activation have passed, the
unitwillswitchitselfoautomatically.
If a switch on procedure is done and the arming
cable is not inserted, the unit will countdown from
10 to 1 and after 1 is shown the display will go
blank,theunitisswitchedo.
Amanualswitch-oisalwayspossibleusingthe
push button.
The manual switch-o sequence is the same as
the switch-on procedure (click, light, click, light,
click, light, click). This routine is designed to avoid
accidentalswitch-o.
If the self-test is not successful, an error code is
shown for approximately 2 seconds. See chapter 7.
After an activation the unit switches itself o
automatically.
2.2 Delay time programming
To change the preset delay time, turn on the unit, but
press and hold the button at the fourth (last) click.
The device will perform a self-test. You will see that
the device counts from downwards. After
, the currently programmed delay time (for
example ) will be displayed for one second.
If you want to keep this value, release the button
the moment you see the previously programmed
delay time. If you want to set another time, keep
the button pressed and enter a three-digit number
(between 000 and 999), starting from the left digit.
The display will show with an up-counting
rstdigit.Whenyouseethecorrectnumberfor
therstdigit,releasethekey.Thiswillsavethe
rstnumber.Pressandholdthebuttonagaintoset
the second digit until the correct second digit is
displayed and release the button. Program
the third digit in the same way.

- Time CYPRES 2 User’s Guide - page 9
Example:
15 seconds delay requires to enter . The
rstnumbertoprogramisthe0,followedbythe
1,followedbythe5.Whentheprogrammingis
successfully completed, the unit will not display
therstzero(s)tokeepitclear.
You will see (SEconds 15).
Afteryouhavenishedthesetting,theunitwill
switchitselfo.
If you start the delay time programming but do not
complete it (e.g. do not enter the complete 3 dig-
its),thedevicewillswitchoautomaticallyafter
14 hours. After the following power-up, the unit
will display a delay time programming of .
If the programming is , the unit will activate
immediately when the arming cable is pulled.
2.3 Handling
To use the preset device just switch it on. It will
run through the selftest, it will pass the
and will then display the previously programmed
delay time (in this example ).
The unit is now reday for operation. As soon as
you pull the arming cable, the device counts down
from the displayed to and activates
when is reached.
If you want to stop the countdown for any reason,
fully insert the arming cable. One second after you
have pushed back the arming cable, the countdown
stops and the device resets itself to the programmed
value (in this example the appears again
on the display).
The unit is ready for operation again. Another way
tostopthecountdownistoswitchothedevice
via the pushbutton.
If the countdown has to be stopped, this has to be
done at least 1 second before reaching the zero.

3. Access to unit information
To view the unit informations press the button im-
mediately when the appears at the end of
the switch-on procedure and hold it.
Each value is displayed for 5 seconds, then the
next value shows up.
You can stop the information sequence whenever
you want by just releasing the button.
Whenyoulet thebuttongo,thepreviouslypro-
grammed delay time is shown again, the unit is on
for the next 14 hours.
* After the last scheduled maintenance has been
performed, the words ‘maint. no’ and the date of
the end of service 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 tilt!
It is easy to change a 1-pin CYPRES to a 2-pin
CYPRES or vice-versa, by swapping cutter types.
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 motion.
Do not twist!

Notes:
1. CYPRES 1 eldreplaceablecutters (no alumi-
num grip) can be used with CYPRES 2. They
will function properly, however this combination
is not water-resistant.
CYPRES 2 cutters (identified by aluminum
grip) can be used with any CYPRES 1 with the
eldreplaceablecutterconnector.Theyfunction
properly - but this combination is not water-
resistant.
2. Release units (cutters) are numbered via a heat
shrink tubing placed on the cable. This number
identiesthecutter.Alistofcutternumberswith
corresponding dates of manufacture is available
on www.cypres.aero
3. Use a one-pin cutter in a one-pin container and
a two-pin cutter in a two-pin container.
5. Water contact
Because of its arming cable, the Time CYPRES 2
is not waterproof.
If a Time CYPRES 2 had a water contact, please
send it in for a free inspection.

6. Important notes for users
• CYPRES2isshieldedagainstradio-transmitter
signals.Extreme concerted eortshavebeen
taken to protect the Time CYPRES 2 from
„radio pollution“. Although the extraordinary
shielding system of the Time CYPRES 2 has
been investigated thoroughly, it is impossible to
have 100% protection. It is still recommended
to avoid strong radio-transmitters. Please con-
tact Airtec if you have questions.
• Areleaseunitthathasactivatedbuildsupahigh

Never attempt to open it by force. It can, how-
ever,bestoredsafelyforanindeniteperiod
of time, provided that it has not been damaged.
7. Error Display
If any irregularities are detected during selftest, the
Time CYPRES 2 shows a number on the display
forapprox.2seconds, then it switches itself o
(display goes blank).

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.

8. Installation
All rigs that are given free for the installation of an
TimeCYPRES2havebeenatAirtecinBadWün-
nenberg, Germany for a thoroughly investigation.
In this procedure extensive testing of the function
by an installed Time CYPRES 2 has been executed
and the installationinstructionshavebeendened
in conjunction with the harness and container
manufacturer.
Under no conditions deviation from these instruc-
tions are allowed.
Whentheunitisinsertedintoitshousingintherig
the 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-adjustable
ap.Ifyouhavetostowboth,thethinnercutter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 circle in order to
avoid twists. Always avoid pulling, bending, twisting
or kinking the cables.
Whenpreparingacontainerforadummydrop,please
make sure that the mounting of the cutter ensures that
the cutting action results in a container opening.

9. Technical service
CYPRES 2’s extremely reliable functioning is
attributable to four factors: the exclusive use of
carefully pretreated and approved parts, strict and
detailed manufacturing procedures, continuous
quality control and monitoring throughout the
manufacturing process, and regular periodic techni-
calservicing(maintenance).Weoermaintenance
for four main reasons:
1. Deviations between nominal and actual values
are corrected to ideal values. Every detail is
observed. Signs of wear and tear are often cor-
rected and sometimes even ‘cosmetic’treatment
is performed.
2. The technical condition of each unit is analyzed.
The fact that a very high percentage of units
are returned for periodic maintenance allows
us to see statistical trends and predict potential
problems at a very early stage. This means
that it is often possible to prevent situations by
makingmodicationsduringthemaintenance
process,ratherthanhavingtoxproblemsthat
result in downtime later.
3. Experience has shown that during the period
of a maintenance cycle (4 or 5 years), changes
and improvements do happen. Applicable up-
dates are performed during maintenance. Such
updates may arise from technical improvements
or enhanced 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 maintenance element is
the individual pre-adjustment of each unit for
the next cycle. A unit will not be returned until
ahighlevelofcondenceisreachedinterms
of predicting the unit’s correct function for the
next cycle.
CYPRES 2 offers two scheduled maintenance
events within the unit’s service life.
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).

page 16 - Time CYPRES 2 User’s Guide -
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.
It’s smart to choose a suitable time during the 13
month window for sending the unit in for main-
tenance, rather than waiting until the last possible
moment, or until the beginning of the next season.
Because of the 252,000+ maintenance procedures
performed to date on CYPRES, and lots of improve-
ments incorporated into the design of CYPRES 2,
Airtec has determined that it is possible to extend the
maintenance window to 13 months on
CYPRES 2.
This maintenance window gives you more free-
dom, and avoids maintenance down-time at the
wrong time of the year - please use this feature
wisely!
At any time it’s possible to check the date of the
next recommended maintenance. (See chapter 4.5)
If the unit enters 6 months before the recommended
maintenance due date, the maintenance date (next
maint. in month / year) will automatically be
shown at each self-test. 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 number
of maintenances and the
necessary time to do them
increases February-May.
For quicker service, a date
between June and January
is a better choice.
During the CYPRES 2
service life, the skydiver
should not have any operation costs other than the
2 recommended maintenance fees (except for an
activatedcutterorlter).

10. Repacking of the parachute
You should definitely take advantage of the
CYPRES closing loop and disc system.
Previous closing loops - made by old suspension
lines or Kevlar or Darcron or Spectra or Optima
- were thick and not very slippery and not very
exible.
On container openings, when circumstances are
unfortunate, these loops can be squeezed between
the grommets.
That may cause a delay of the opening or even
avoid the opening at all for some seconds.
Fatalities did happen because of that.
Airtec has improved the closing loop system.
This is the result:
“Smiley“
CYPRES Loop
- no sharp edges
- minimal loop tearing
-extremelyexible
- extremely slippery
- breaking strength: 408 lbs
- diameter: 11/16 inch
CYPRES disc

- Time CYPRES 2 User’s Guide - page 19
The CYPRES closing loop is far safer than previ-
ous loops because:
- theextrathin,exibleandslipperyloopmate-
rial reduces the possibility of the loop jamming
in the grommets dramatically
- loop tearing is extremely reduced, because the
fastening disc has no sharp edges
- the tensile strength is far greater (in excess of
408 lbs) than with former loops
- the extremely thin material which is impreg-
nated with silicone reduces the pull force
which is required to pull the ripcord up to 50%
(although the tension on the container remains
the same)
