NiCAD (Nickel-cadmium) Batteries
The optional NiCAD battery cartridge (PC-8201-90) can be used in
place of the regular battery pack containing standard AA bat¬
teries. The advantage of using the NiCAD battery cartridge is that
it may be recharged more than 500 times by using the AC Adapter
(PC-8271 A-01).
The insertion and removal of the NiCAD battery cartridge in the
PC-8201 is done as described in the following section on battery
installation, however the cartridge may not be opened. This battery
cartridge is recharged continuously when the AC Adapter is connect¬
ed to the PC-8201, even when the power switch is turned OFF.
The AC Adapter supplies electrical power to the PC-8201 via a wall
outlet while the NiCAD battery cartridge s recharging. The
rechargirg process is completed in approximately 48 hours. The
NiCAD battery cartridge should have a full charge prior to using it
for the first time.
The NiCAD battery cartridge should be recharged as soon as possible
after the Low Battery LED lights up. Keep in mind that the
NiCAD battery cartridge may not reach its full potential until the
unit has been used and recharged 2 or 3 times. Once the NiCAD
battery cartridge can no longer hold a charge, the entire cartridge
must be replaced.
Careful handling of this cartridge is necessary for optimum perform¬
ance. The connector terminal portion of the cartridge should never
be touched, and the cartridge should never be dropped. The
cartridge should be stored in an area with low humidity.
The use of any AC Adapter other than the (PC-8271 A-
01) can cause serious damage to the NiCAD battery
cartridge.
