Warning
Skydiving is a dangerous activity which can result in serious or even fatal injury.
Trainingandexperiencearerequiredinordertoreducesuchrisk. Usingthem2safety
device during skydiving can signicantly reduce the risks. Never solely rely on the
m2, since it is not the primary tool for opening of your parachute. Remember the m2
is an electronic device and, just like other equipment, it can fail. In the case of some
collisions, the m2may cause death. Read the instruction manual thoroughly prior
to using the device. The device is not designed for PARAGLIDING, PARASCENDING,
PARASAILING, or BASE JUMPING. The failure-free function of the m2cannot ensure
the correct function of the parachute system, i.e. the harness with the container,
the reserve parachute, and the accessories. The m2device is only responsible for
cutting a closing loop of a reserve parachute which is properly pulled through the
cutter!!!

1. Introduction
Thank you for buying the AAD m2, and we hope you will never nd yourself in a situation where you need it. Simply switch the m2device on
in the morning prior to the rst jump and it will guard your safety without any further bother.
The Automatic Activation Device„AAD“ is an automatic electronic safety device. The m2device continuously checks that the skydiver is not too
close to the ground without an open and functional parachute. It detects a skydiver’s falling speed and altitude. If the m2assesses the situation
as hazardous for the skydiver, the cutter automatically cuts the closing loop of the reserve parachute, which starts the process of opening the
reserve parachute. It is designed and manufactured based on the latest ndings focused on sports skydiving, and its function fully meets the
demands of the current skydiving sport.
Professional designers, who are also excellent skydivers, have contributed to its development. The device is available in m2EXPERT,
m2STUDENT, m2TANDEM andm2SPEED versions. Upon switching on the m2it works fully automatically, without user intervention.
The m2’s main advantages are:
• ultralowpowerdesign–noneedforbatteryreplacementthroughoutitslifetime
• 15-yearlifetimewithoutservicingrequiredbythemanufacturer

capacity for its entire service life without the necessity of battery replacement.
It is built into a harness in minimum space and allows the skydiver to open the reserve parachute primarily with the manual release handle.
Individual Device Parts
The m2consists of a processing unit in which the battery is stored, a processor, an electronic circuit and a pressure sensor. The processing
unitistightlyconnectedviacabletothecontrolunit,withamulti-functiondisplayandcontrolbutton.Thecutterisconnectedtothe
processing unit body via a connector as a removable device part.
Never break or pull the control unit cable or the cutter cable!!!
Processing Unit
The body of the processing unit is made of aluminum alloy with a nished surface. The front face of the processing unit shows the m
2
logo,
and on the back is the identication label. The lter is placed between the cable penetrations on the top. The whole body is sealed watertight.
On the identication label is the following information:
•SN(serialnumber),uniqueproductionnumber
•MFD (Manufacture Date), year and month of manufacture
•m2AAD, commercial designation
•Made in Czech Republic andEU, country of origin

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 control unit has
adisplayforvariousicons,thecontrolbuttonandthelabelspecifyingthedeviceversion.Thelabelalsoincludestheunits-metersor
feet. If the label indicates„meter“, all of the entered and displayed altitudes are in meters. If the label indicates„feet“, all of the altitudes
entered and displayed are in feet.
Cutter
The cutter is made from stainless steel and ensures cutting of the reserve parachute closing loop, if necessary.
Its shape allows rm xation between the reserve parachute aps and prevents rotation of the cutter body around its longitudinal axis.
It is very scratch resistant. It is connected to the main unit by a exible cable and connector. The connector is completely inserted into
the processing unit and is secured with a locking screw to prevent accidental removal.

3. Function
Function principal
The m2 deviceisanelectronicsafetydevice,operatingontheprincipalofpressuresensing.Theprimarytoolfordeterminingthealtitude
and the falling speed is a pressure sensor.The calculation of the altitude is made based on the dierence of two atmospheric pressures:
the current altitude pressure and the landing area „GROUND ZERO“ pressure. The landing area pressure is measured and set when
the device is switched on, during calibration. This pressure is automatically adjusted to barometric pressure changes during the day
withouttheneedofuser intervention.The m2 checkstheambientbarometricpressureevery32secondsandevaluatespossibleaircraft
takeo. If takeo is conrmed, the m2 will start checking the skydiver’s altitude and his falling speed.The pressure sensor monitors the
actual atmospheric pressure 8x per second during free fall; the received information is evaluated by means of a microprocessor and
sophisticatedsoftwareandrecalculated totherealfallingspeedandactualaltitude.Thankstothis,the
m2 deviceisabletousethecutter
tocuttheclosinglooponthereserveparachuteandinitiateitsopeninguponmeetingthepresetlimitsofthefallingspeedincombination
with the altitude above landing area. The device is activated only upon meeting the set limits which are dierent for the individual
m2 EXPERT, m2 STUDENT, m2 TANDEM or m2 SPEED.
The device is responsible solely for cutter activation as per specied limits, and for cutting the closing loop of
the reserve parachute. It is not responsible for the correct and full function of the whole harness system with the
container, reserve parachute, and other accessories!!!
Function Modes
The m2was designed to be an extremely simple safety device to use. Most users just want to switch the AAD on before
the rst jump and no longer worry about it. In addition to the standard mode, which the user will use the most, the m2
software also enables other functional modes: a mode for landing above the aircraft’s take o, a mode for landing below the
aircraft’s take o and X mode, for the temporary change of parameters. Changing the mode changes the device parameters.
Therefore, always think twice about what you are doing. The mode is selected during the m2activationsequence.After
manual or automatic device switch o, the default STANDARD mode is set. The current active mode is displayed by an icon
on the display.
