M-175 BATTERY CHARGING
Battery Charging
1. Make sure that a seven cell 9 volt Ni-MH rechargeable
battery is used with a minimum of 200 mAh capacity.
(Alkaline batteries must not be charged.)
2. Make sure the M-175 is turned OFF.
3. Note that the red charging indicator on the charger is ON when the M-175
is plugged into the charger through the audio output jack.
4. When using the NBC 9-2C charger allow the battery to charge for 14 hours
for a full charge. Unit must then be unplugged. When using the
NBC 9-3-1 digital fast charger the charger will automatically end the
charge cycle and the red LED will change to green. With the NBC 9-3-1
charger the unit may be left in the charger until the unit is used.
5. Periodically open the battery compartment on stored COMTEK units to
check for battery leakage. If a battery is leaking, it must be discarded,
and the battery compartment must be cleaned or returned to COMTEK’s
service department for repairs.
