Battery Charging
1. Make sure that a seven cell 9 volt Ni-MH rechargeable
battery is used with a minimum of 150 mAh capacity.
(Alkaline batteries must not be charged.)
2. Make sure the PR-216 is turned OFF.
3. Note that the red charging indicator on the charger is ON when the PR-216
is plugged into the charger through the audio output jack.
4. When using the NBC 9-2C charger allow the battery to charge for 12 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 this 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.
