Recharging the NiCd Battery Pack
If the portable will not turn on or if the message LOW BATTERY appears
on the display, the battery pack needs recharging. To recharge the NiCd
battery pack, use a cable and an external 9-volt power adapter (refer to
Figure D-1 on page109). A full charge takes about e ight hours.
To recharge the NiCd battery pack, complete the following steps:
1. If the portable is on, turn it off.
2. One of the connectors on the cable has the cable number on it.
Plug that connector into the cable input jack on the bottom of the
portable.
3. Attach the small, round plug of the 9-volt power adapter to the
round power input jack on the cable connector labeled
COMPUTER. Plug the other end into an outlet or power strip.
Use the PT Dock to recharge the NiCd batteries. Leave the batteries in
the unit while it is in the Dock. The batteries recharge while the READY
light is on. (Make sure Switch 2 in the portable’s battery compartment is
in the NiCd position; refer to Figure E-1.)
Caution: Do not short-circuit a batter y—damage to the battery
can result. Do not incinerate, crush, or puncture
batteries. The electrolyte contained in NiCd batteries is
composed of caustic materials that are harmful to the
eyes and skin. Dispose of batteries in compliance with all
applicable regulations.
Caution: Use only a power adapter supplied by a PSC dealer.
Using another adapter can damage the unit.
