- english version -
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 canopy
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 moment
which, no matter how experienced and cautious
you are, justies that you haven‘t left your safety
to chance.

1. Function
1.1 Design philosophy
CYPRES, which is the acronym of „CYbernetic
Parachute RElease System“, is an automatic activa-
tion device which meets all needs, requirements,
and desires of today‘s skydivers.
The operation is easy: If you jump from your DZ
into your DZ just switch it on prior to the rst jump
of the day. It is not necessary to switch it off, be-
cause CYPRES will do this itself. (See chapter 4.3)
The weather is constantly checked by CYPRES
over the day by measuring the air pressure twice
a minute. This means that the unit is always cali-
brated to the precise ground level.
The various CYPRES model parameters have been
chosen to cover the needs of the vast majority of
skydivers, and also not to restrict them during
common skydiving operations. More than 123
Million jumps since 1991 have proven the proper
design of these parameters. (Special activities may
require special consideration or CYPRES settings.)
High vertical speed at a low altitude causes
CYPRES to take action. (For Expert model 35
meter per second, which is approx. 70% of typical
freefall speed.)
The CYPRES family of AAD‘s work with remark-
able reliability. To date CYPRES units have saved
the lives of more than 4000 skydivers, without a
single unit ever refusing to activate and cut through
the loop when the conditions were met.
CYPRES is surely the most reliable piece of sky-
diving equipment ever produced.
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.

The CYPRES 2 combines tried and true quality
and reliability with achievements, technology and
discoveries made during all the years of continued
research and development since 1991.
The CYPRES 2 offers numerous features and at-
tributes including:
- unit is waterproof for up to 24 hours down to a
depth of 8 feet (2.5 meters) in fresh or saltwater
- power supply of CYPRES 2 costs zero money
for the user. There is no need to observe a
replacement date, record the number of jumps
made, monitor the voltage during self-test,
watch for a ‘low bat’ sign, purchase a battery,
or have a rigger open or repack the reserve for
this reason.
- several unit informations are accessible from
the display: ight counter, serial number, next
possible maintenance due date, settings
- reminds you when the recommended mainte-
nance date is near
- small and light
- robust, rigger friendly case, with rounded cor-
ners and edges, and in addition it is waterproof
- extended maintenance window: +/- 6 months
from month of manufacture, no down-time
during the busy part of the year regardless of
month of manufacture
- self-test is completed in 10 seconds

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.
Do not pull, lift, carry or throw CYPRES by the cables

1.3 How CYPRES works
Every time CYPRES is switched on, it measures
the air pressure several times in a short period of
time, takes the average value as the value for ground
level, thus „zeroing“ itself. This happens during the
integrated self-test.
While it is in use, CYPRES constantly checks the
air pressure while on the ground and, if necessary,
adjusts to changing weather conditions. Even though
you might need to reset your altimeter before a jump,
CYPRES takes care of itself. This very accurate cali-
bration is the basis for CYPRES to recognize exactly
the activation altitude and speed.
The processing unit contains a factory programmed
microprocessor that is capable of real-time calcula-
tions of the jumper‘s altitude and rate of descent based
on barometric pressure.
By monitoring this data, certain criteria are generated
from which conclusions are drawn. Should the con-
clusion be that the jumper is in a dangerous situation
(i.e. still in freefall at a low altitude) the processing
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
cutters passing hole.
Initiating the opening sequence of a reserve container
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
reserve container where it is not exposed to
excessive shock or other adverse inuences.
- CYPRES 2 User’s Guide - page 7
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 classied 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.

1.4 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.

1.5 Operational safety
There are two important points to remember re-
garding the operational safety of CYPRES:
1. CYPRES self-tests automatically every
time it is switched on. After every switch-
on procedure, CYPRES executes a self-test
routine during which all important internal
functions are checked. A positive outcome
to this self-test should assure you of a trou-
ble-free operation for up to 14 hours.
When the display unit shows , the self-
test has been completed successfully. If the
self-test has resulted in errors or discrepancies,
CYPRES will not assume operating mode but
will switch itself off after displaying an error
code. This error code indicates why the self-
test process was aborted (see chapter 5).
2. CYPRES has fail-safe error detection. Two
processes are activated in CYPRES once the
unit has been switched on: a primary work-
ing process and an independently operating
controlling process that monitors the working
process continuously. In case of errors while
the working process is active, the backup con-
trolling process should switch the unit off.
Depending on the type and potential impact
of the error, CYPRES can either be switched
on again or it will stay in shut-down mode
permanently. With certain error codes (see er-
ror code list in chapter 5), it is not possible for
the user to reactivate the unit. In such cases,
CYPRES must be sent to the manufacturer or
service center for inspection and adjustment.
Malfunction can result in false activation / no
activation: 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. Such inappropriate act can easily injure
or kill you or others. If you or your friends or relatives are
not willing to accept these uncertainties and risks, then
you must not use CYPRES.

2. Product overview
CYPRES 2 is available in six models:
Expert CYPRES 2
Student CYPRES 2
Tandem CYPRES 2
Speed CYPRES 2
changeable MODE CYPRES 2
Wing Suit CYPRES 2
Converting models
A conversion between the four
CYPRES 2
models
Expert - Student - Tandem - Speed is possible.
This procedure has to be performed by the manu-
facturer or the service center. This includes new
settings, a new color corresponding button, a new
label, and a complete functional test.
After a model change, the settings of the chosen
model will be reset to the standard settings (see
chapter 14).
Use in a 1-pin reserve container and
the use in a 2-pin reserve container
All CYPRES can be used in both container types.
With the plug-and-socket cutter connection a swap
from 1-pin cutter to 2-pin cutter or vice versa can
be simply done by unplugging and plugging-in
without opening the unit and without the use of
any tools. (See chapter 6)
Feet / Meter version
Every new CYPRES can either display altitude in
feet or meters. If your CYPRES does not meet your
personal preference, see chapter 4.4.5 for changing
the scale of the dropzone offset from feet to meter
or vice versa. Once you have set it, leave it as long
as the unit is in your use.
(If your CYPRES does not show or
on the display when changing the dropzone offset,
then it is an older version that is not capable of
switching the scales.)
