7.2. Battery alarm threshold
The COCKPIT
MM
features a battery alarm and a voltage display. You can read the bat-
tery voltage in the display, if you are in the INFO menu level (see menu overview,
displays “INFO1” or “INFO2”).
When the battery monitor detects that the voltage of the transmitter battery has
fallen below the alarm threshold, a quadruple beep sounds as a warning. The sec-
ond warning level is indicated by a continuous beep.
You can vary this safe threshold level within the range 6.8 to 7.2 V (default = 7.0 V).
The 6.8 V setting gives the longest operating time per battery charge.
Caution: if the warning beep sounds, cease operations as quickly as
possible and recharge the transmitter battery!
This is how you alter the warning threshold:
Procedure Display
1.
In the SETUP menu select the BATTW setting and

7.3. Operating hours
The COCKPIT
MM
features an operating hours timer which is dis-
played in the bottom line of operating screen 3. The operat-
ing time can be reset to zero in the TIMER menu.
Possible applications
If you reset the timer to zero every time you charge the transmitter battery, for ex-
ample, you will have a constant reminder on screen of the remaining available op-
erating time. This represents a second method of keeping track of the remaining
operating time in addition to the voltage display.
If you do not reset the operating hours timer, the timer is cumulative and tells you
how long the transmitter has been in use over a long period.
This is how to reset the operating timer:
Procedure Display
1.
In the TIMER menu select the RES OP setting
