6. Control
Control Principals
To switch the
m 2
to the STANDARD-mode, press the control unit button four short times. This also prevents accidental switching on or off.
After the device is switched on, it remains functional for 14 hours, and then turns itself off, regardless of the situation it is in. When not
using your parachute, we recommend manually switching the device off. This saves the battery. After the activation sequence is complete,
the instrument performs a self-check and calibration of zero altitude. If a problem is detected, the device reports an error.
If you are switching the
m
2
on into a mode where you need to specify the altitude, the UP-mode or DOWN-mode, the numerical value of
the altitude is entered by the individual digits. Gradually enter the whole number from left to right, from highest to lowest denomination.
The
m
2
provides all of the digits from „0“ through „9“ for the given denomination, in sequential order. Press to select the value for the
current denomination and it will move on to the next value for entering, until all denominations are entered. The following text provides
examples of input in meters as well as in feet.
If the
m
2
displays the entered value, the whole number will be displayed on the control unit by individual digits from left to right, always
for the given number of places. The number starts and ends with the symbol „-“.
Switching the device on into STANDARD-mode
It is assumed the device is switched off. Shortly press the control button (2) on the control unit body (1). Upon the icon being
displayed (3) immediately press the control button a second time; the icon will be displayed; immediately press the button a third
time; when the icon is displayed, immediately press the button for the fourth time. The flashing icon will be displayed, which
indicates the auto-test and pressure calibration are in progress. Upon completion, the icon will be shown on the display (3).
The device is now on and preset to zero altitude – GROUND ZERO. If you fail to switch off the device, it will automatically switch off after 14 hours.
The button only requires a short press - click. Pressing must occur when the icon appears on the display. If this switching frequency has not
been properly completed, the device will return to the OFF mode. The sequence must be repeated in order to start the device.
Never switch the device on in an aircraft!!!
