4. Operating mode
4.1. Description
The
m
2
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 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 dierent elevations. OFFSEt mode allows the user to enter the elevation
dierence 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 prole
is shown on the display. If the device is switched on in OFFSEt mode, the display shows “oset”, the rst letter of the prole, the entered elevation dierence 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 prole 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 m
2
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 prole (
approx.
450m/
1 475ft - Stu, Int, Pro, Cpi, (ca 900m / 2 950ft
- Tan) to unlock the device.
