WARNING
Skydiving is a dangerous activity that can result in serious or even fatal injury. To reduce these risks, it is
necessary to have training and experience. Using the m2 multi automatic activation device when skydiving can
signicantly reduce these risks. Never rely solely on the m2 multi, since it is not the primary tool for opening
of your parachute. Keep in mind that the m2 multi is an electronic device and, just like any other equipment, it
can fail. In some collisions the m2 multi may even cause death. Read the instructions thoroughly before using
the device. The device is not designed for PARAGLIDING, PARASCENDING, PARASAILING and BASE JUMPING.
Even a awless operation of the m2 multi cannot ensure proper operation of the parachute kit, i.e. the harness
with container, reserve parachute and other equipment. The m2 multi device is only responsible for cutting the
reserve parachute closing loop that is properly pulled through the cutter!!!
The specied activation altitude (AGL) of the m2 multi is based on a skydiver in a stable body position. If the
skydiver is in another orientation, or unstable, this may result in pressure changes that cause the m2 multi to
activate above the specied altitude (AGL). To avoid premature activation of the m2 multi the skydiver should
be in a stable body position and comply with the recommended altitudes (AGL) for main canopy deployment.
In addition, the skydiver should be aware that it is possible to exceed the specied limits under canopy and
cause the m2 multi to activate. The Gravity Index is designed to show you how close you are to activation of the
device under canopy, and we recommend that users become familiar with this feature (see chapter 5.4.3.).

1. Introduction
1.1. General description
Thank you for purchasing the m2multi AAD and we hope that you never nd yourself in a situation in which you would need to use it. Simply switch on the m2
multi in the chosen prole before the rst jump and it will quietly guard your safety from that moment until it is switched o again.
The “AAD” Automatic Activation Device is an automatic electronic safety device. The m2multi device continuously checks that the skydiver is not too close to
the ground without an open and functional parachute. It ensures the fall rate and altitude of the skydiver. If the m2multi evaluates the situation as dangerous
for the skydiver, its cutter automatically cuts the reserve parachute closing loop and thus initiates the sequence of reserve parachute deployment. It is designed
and manufactured on the basis of the latest ndings focused on sport skydiving and its functions fully comply with the requirements of current skydiving sport.
Professional engineers who are themselves excellent skydivers participated in its development. The device has ve dierent prole settings:
STUDENT, INTERMEDIATE, PROFESSIONAL, CANOPY PILOTING and TANDEM. When switched on, the m2multi works fully automatically, without any user
intervention.
1.2. Main advantages
The main advantages of the m2multi device are:
- ultra low power design - no battery replacement necessary for the service life duration
- service life 15 years + 6 months without the need to perform the prescribed servicing by the manufacturer
- compact smooth rounded metal construction
- minimum thickness of the body and the control unit
- water resistance up to 2m in salt or fresh water
- simple operation and many sophisticated additional features
- special at cutter design with a knife to cut the closing loop
1.3. Operating principle
The m2multi is an electronic automatic activation device, operating on the principle of pressure reading. The primary means for detecting the altitude
and fall rate is a pressure sensor. The altitude is calculated based on the dierence between two atmospheric pressures.The pressure at current altitude and
pressure on landing location“GROUND ZERO”. The pressure on the landing location is measured and set after switching on the device during calibration.
This pressure is automatically adjusted by a change in barometric pressure during the day without the need for user intervention. The m2multi checks
the ambient barometric pressure every 32 seconds and it determines whether the aircraft has taken o. If yes, it begins to monitor the skydiver’s altitude
and fall rate. The pressure sensor measures the atmospheric pressure 8x per second in free fall.
The information collected is evaluated by means of a microprocessor and ingenious software and it is converted to real fall rate and altitude. Thanks to this,
the m2multi device is capable of meeting the preset criteria of fall rate in combination with altitude above the landing location, cut the reserve parachute
closing loop by means of the cutter and thus initiate the deployment sequence. The device is activated only in the case the preset criteria are met; the
criteria dier depending on the set proles - STUDENT (Stu), INTERMEDIATE (Int), PROFESSIONAL (Pro), CANOPY PILOTING (Cpi) and TANDEM (Tan).

2.1. Construction
The m2multi is designed to best meet the requirements for durability and correct operation in all situations. It strives not to restrict the
skydiver. It works with minimum power consumption, which allows it to maintain sucient capacity of the energy source for its entire service
life without having to replace the battery. It is built inside a minimum-size cover and thus gives the skydiver the possibility to open the reserve
parachute without using the manual handle. The m2multi consists of a processing unit with the battery, processor, electronic circuits and a
pressure sensor. The processing unit is connected to the control unit by means of a cable; the control unit contains a multifunction display and
control button. The cutter connected in the processing unit body via a connector as a removable part of the device.
2.2. Processing unit
The body of the processing unit is made of aluminum alloy and its surface is coated. The front face of the unit bears the m2multi logo and on
the back there is the identication label. Between the cables on the top side there is a lter. The whole body is watertight.
The identication label indicates the following information:
- SN (Serial Number), unique serial number
- MFD (Manufacture Date), year and month of manufacture
- m2multi AAD, commercial designation
- Made in Czech Republic and EU, country of origin
- logo and other specications required for such a device

2.3. Control unit
The body of the control unit is made of stainless steel and is connected to the processing unit by a exible cable. The unit has a display for the
various icons and a control button.
2.4. Cutter
The cutter is made of stainless steel and cuts the reserve parachute closing loop, if necessary.
Its shape allows it to be rmly xed between the reserve parachute container aps and it prevents the cutter body from turning around its
longitudinal axis. It is highly scratch resistant. It is connected to the main unit via a exible cable and a connector. The connector is completely
inserted into the processing unit and is secured with a locking screw to prevent accidental removal.

3.5. AdJUSt description and use
The individual proles and their activation parameters are xed in the process of manufacture. Some users may prefer a higher activation
altitude, which gives them more time to deal with an emergency in case of activation. In some countries or at some dropzones a higher
activation altitude may be required by local regulations. The AdJUSt function allows the user to modify the current prole and increase the
activation altitude in case this is considered necessary. In the current prole the“Top”activation altitude may be increased in several steps, A1
to A9. The individual increments are approx. 30 m / 100 ft. The maximum increase in the activation altitude is approx. +270 m / 900 ft. The
AdJUSt setting is permanent and is displayed together with the current prole on the control unit display.
Warning:
- The altitude lock increases adequately according to the selected step A1 to A9! (Section 7.2.)
- Take care to open the main parachute in time as you may quickly reach the activation altitude!
Procedure of setting the AdJUSt function can be found in Section 6.3.

4. Operating mode
4.1. Description
The m2multi device may be switched on in several modes. The mode is selected when the device is switched on and remains active until it is switched o again
- the selection is not permanent. The various modes are used to distinguish the type of jump and they determine the device behavior. BASIC mode is used most
often - when the skydiver performs the jump at an airport (dropzone) and the aircraft take-o point and the landing location are thus the same - they are at the same
elevation. OFFSEt mode must be always used when the take-o and landing locations are at dierent elevations. OFFSEt mode allows the user to enter the elevation
dierence between the aircraft take-o point and the landing location during the switch on sequence. If the device is switched on in BASIC mode, the current prole
is shown on the display. If the device is switched on in OFFSEt mode, the display shows“oset”, the rst letter of the prole, the entered elevation dierence between
the aircraft take-o point and the landing location, and the units icon. When the button is depressed, the full description of the current prole is displayed.
4.2. List of modes
- BASIC It is used when the skydiver takes-o and lands at the same place.
- OFFSEt HI It is designed for situations when the landing location is higher (elevation) than the elevation at which the device was switched on.
- OFFSEt LO It is designed for situations when the landing location is lower (elevation) than the elevation at which the device was switched on.
4.2.1. BASIC - mode
The BASIC mode shall be used always, when the skydiver starts (take-o point of the aircraft), and lands at the same place, usually the drop zone and
does not need to change the device parameters due to higher or lower landing location. The landing location is in this case at the same elevation as
the take-o point of the aircraft, where the
device was switched on. Always switch on
the device at the landing location. The m2
multi requires the plane to immediately
climb approx. 40m/130ft above Ground
Zero for a correct detection of start-up
and remain above this altitude until the
skydivers jump o. In the next phase of the
ight it is necessary to exceed the Altitude
lock (watch out for increasing the unlocking
altitude, see Section 6.3.) according to
the preset device prole ( approx. 450m/
1 475ft - Stu, Int, Pro, Cpi, (ca 900m / 2 950ft
- Tan) to unlock the device.

4. Operating mode
4.2.2. OFFSEt HI - mode
OFFSET HI mode is designed for situations when the landing location is higher (elevation) than the elevation at which the device was switched
on (take-o point of the aircraft). It is necessary to set the elevation dierence of the landing location in the range of approx. +/- 999m /
+/- 2 990ft. Reminder: This is a temporary setting for one jump only! The settings can only be done when switching on the device. When
using the OFFSET HI mode, the altitude at which the altitude lock opens relates to the preset landing location elevation. It is also necessary
to bear this fact in mind in case of an emergency situation!
Switch on the device at the take-o point of the aircraft. For correct operation of the m2multi it is necessary to preset the elevation dierence
between the landing location and the take-
o location. Enter the numeric value of the
dierence between the parachutist landing
location and the aircraft take-o point. The
altitude lock is in this case relates to the landing
location, i.e. according to the prole either
approx. +450m / +1 475ft for proles Stu, Int,
Pro and Cpi or about +900m / +2 950ft for prole
Tan plus the specied elevation dierence. In
such case, the m2multi requires the plane to
immediately climb approx. 40m/130ft above
the take-o point for a correct detection of
start-up and remain above this altitude. After
reaching the preset altitude plus approx. 40m /
130ft and exceeding it, the aircraft shall remain
above this level until the skydivers jump o.
If the skydiver lands at the preset altitude,
the device switches o automatically. If the
device does not switch o automatically, do it
manually after landing. Switch the device on
only before the following jump. This ensures
perfect calibration and operation of the m2
multi device.

4.2.3. OFFSEt LO - mode
OFFSET LO mode is designed for situations when the landing location is lower (elevation) than the elevation at which the device was switched on.
In this mode, you can set the elevation dierence of the landing location in the range of approx. +/- 999 m / +/- 2 990ft. Reminder: This is a
temporary setting for one jump only! The settings can only be done when switching on the device. When using the OFFSEt LO mode, the
altitude at which the altitude lock opens relates to the preset landing location elevation. It is also necessary to bear this fact in mind in
case of an emergency situation!
Switch on the device at the take-o point of the aircraft. For correct operation of the m
2
multi it is necessary to preset the elevation dierence between
the landing location and the take-o location. Enter the numeric value of the dierence between the parachutist landing location and the aircraft take-
-o point. The altitude lock is in this case relates to the landing location, i.e. according to the prole either approx. +450m / +1 475ft for proles Stu,
Int, Pro and Cpi or approx. +900m / +2 950ft for prole Tan minus the specied elevation dierence. In such case, the m
2
multi requires the plane to
immediately climb approx. 40m/130ft above the take-o point for a correct detection of start-up and remain above this altitude for at least 90 seconds.
After these 90 seconds it is possible to descend below the take-o altitude but not below the preset landing location altitude plus approx. 40m / 130ft.
If the skydiver lands at the preset altitude, the device switches o automatically. If the device does not switch o automatically, do it manually after
landing. Switch the device on only before the following jump. This ensures perfect calibration and operation of the m

4. Operating mode
4.3.3. OFFSEt LO mode - setting and example
Limit warning! The OFFSEt LO mode can only be used locally on the same isobar!
Example: The landing location is about 175 m below the point at which the device was turned on (take-o point).
Briey press the yellow button on the control unit, GO-ON sign appears (for 2 seconds). Do not hold the button, depress it only briey!!!
During the time the GO-ON sign is displayed, preferably immediately after it comes on, depress the yellow button briey once again. The GO-ON
sign appears again. After the yellow button is depressed again (GO-ON sign displayed), the last preset PROFILE can be seen on the display (Stu,
Int, Pro, Cpi, Tan). DO NOT CONFIRM the selected PROFILE and wait for OFFSEt function to show; conrm this function by pressing the button.
The display shows -LO (decreased landing elevation). Conrm -LO by pressing the yellow button at the moment the required function is indicated
on the display. (Note: If the device had already been set for OFFSET in the given mode +/-, the display shows the last selected setting for two
seconds.) If the original setting is not conrmed by depressing the button, the display will show the initial letter of the set PROFILE (Stu, Int,
Pro, Cpi, Tan), then the minus sign (-) and in two one-second intervals it displays the numbers to allow exact setting of the required altitude.
The rst number is hundreds of meters, followed by tens and single meters. After entering the required oset, the device calibrates. The initial
letter of the PROFILE remains on the display and above it is the sign oset followed by a minus sign (-) and the set meters. For a better control
of the selected PROFILE, it is possible to press the button once, the whole set PROFILE is shown and above it is the oset sign, after four seconds
the GO-OFF sign appears in case you intend to switch o the device completely, and the INFO menu also comes on that allows access to the
information menu.
