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 m multi automatic activation device when skydiving can significantly reduce these risks. Never rely solely on the m multi, since it is not the primary tool for opening of your parachute.
1. Introduction 1.1. General description Thank you for purchasing the m multi AAD and we hope that you never find yourself in a situation in which you would need to use it. Simply switch on the m multi in the chosen profile before the first jump and it will quietly guard your safety from that moment until it is switched off again. The “AAD”...
2. m multi description 2.1. Construction The m multi 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 sufficient capacity of the energy source for its entire service life without having to replace the battery.
2. m multi description 2.3. Control unit The body of the control unit is made of stainless steel and is connected to the processing unit by a flexible cable. The unit has a display for the various icons and a control button. Only press the control button with the pad of your finger! Display...
3. Profiles 3.1. Description Profile is a set of parameters that determine the conditions for activation of the m multi device. The most important parameters are the acti- vation altitude and the fall rate. The parameters of the individual profiles are fixed. The user may select and set a profile depending on his skills, used parachute and sports performance or focus.

3. Profiles 3.2.2. INTERMEDIATE (Int) The INTERMEDIATE profile is designed for basic training of advanced students and AFF. It is activated when the height above the landing loca- tion is lower than approx. 330m / 1 100ft and fall rate is higher than approx. 20m.s / 45mph.

3. Profiles 3.2.4. CANOPY PILOTING (CPi) The CANOPY PILOTING profile is primarily intended for the Canopy Piloting sports discipline. The profile is used only for the most experienced pilots with extremely quick parachutes and vast experience. It is activated when the height above the landing location is lower than approx. 270m / 885ft and fall rate is higher than approx.
3. Profiles 3.5. AdJUSt description and use The individual profiles and their activation parameters are fixed 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.
4. Operating mode 4.1. Description The m multi 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 off 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-off point and the landing location are thus the same - they are at the same elevation.
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-off point of the aircraft). It is necessary to set the elevation difference of the landing location in the range of approx. +/- 999m / Reminder: This is a temporary setting for one jump only! +/- 2 990ft.
4. Operating mode 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. Reminder: This is a In this mode, you can set the elevation difference of the landing location in the range of approx. +/- 999m / +/- 2 990ft. temporary setting for one jump only! The settings can only be done when switching on the device.
4. Operating mode 4.3. Examples of using modes 4.3.1. BASIC mode - example BASIC mode shall be used always, when the skydiver takes off and lands on the same location, usually drop zone (takes off and lands at the same elevation). The display shows: Switched on in the BASIC mode with STUDENT (Stu) profile 4.3.2.
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-off point). Briefly press the yellow button on the control unit, GO-ON sign appears (for 2 seconds).

5. Controls 5.4.4. Gravity index G - Gravity index is the percentage of the highest achieved fall rate in the activation zone during the last jump, when 100 % is the activation speed of the currently used device profile. After landing, the skydiver may check how close he was to the device activation limit during his flight on the parachute in the activation zone.

9. Maintenance 9.3. Battery The m multi device is designed to last its whole service life without the need to replace battery. If for any reason the battery fails, it must by replaced by the manufacturer. In case the battery indicates for example 1 % remaining, there is no need to worry, there is still enough reserve power. 100 % is displayed only the first time the m multi is switched on by the manufacturer.
