APPENDIX D
When Using The NiCad or NiMH Battery Pack*:
Fully charge the battery pack before its first use. The battery pack
requires 12 hours for a full charge and should not be charged in excess of
this time period.. Charge only with the VHF 720 Charging Unit provided
with the Battery Pack. Partially discharging a nickel-cadmium battery and
then recharging it causes a phenomenon referred to as “memory reset”.
When a battery that is not fully discharged is then recharged, it resets the
memory in proportion to the amount of previous discharge, resulting in
a gradually decreasing recharge capacity. To ensure that this type of
battery pack retains its full capacity, it should be almost fully discharged
(when the battery symbol blinks) and then recharged completely after every
few cycles of use.
* Municipal Law requires for environmentally sound
collection and recycling or disposal of nickel-
cadmium and Nickel Metal Hydride batteries.
Contact your local waste management official for
instructions on disposal.
