Battery Charging
1. Make sure that two AA size 1.2 volt Ni-MH rechargeable
cells are used with a minimum of 1400 mAh capacity.
(Alkaline batteries must not be charged.)
2. Note that the red charging indicator on the charger is “ON” when the
PR-75a is plugged into the charger through the audio output jack.
3. When using the NBC 3-1 charger allow the battery to charge for 12 hours
for a full charge. The unit must then be unplugged. When using
the NBC 9-3-12 or NBC 9-3-1 digital fast charger, the charger will
automatically end the charge cycle and the red LED will change to green.
With this charger, the unit may be left in the charger until the unit is used.
4. 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.
