Installing and Replacing Batteries
Battery tips
m Batteries are inherently hazardous due to internal caustic
materials and high energy levels. For this reason, always
handle batteries carefully. Do not drop, puncture,
disassemble, mutilate, or incinerate batteries.
m Do not leave batteries in hot places.
m Never remove the main batteries and the backup battery
from the MessagePad at the same time. If you do, the
MessagePad will lose information that it needs to operate
properly. If such an information loss occurs, you must
restore the MessagePad’s information from a backup copy.
m Use only alkaline AA batteries or the rechargeable battery
pack designed for your MessagePad. The battery indicator
doesn’t work with other types of batteries, and your
MessagePad can run out of power with little or no warning.
m Always turn off the MessagePad before changing the
batteries, to minimize the chance of losing your information.
m Follow instructions carefully when replacing the backup
battery. Make sure you insert the battery + side up;
installing the battery incorrectly may cause a hazard.
m Do not short-circuit battery terminals—that is, do not touch
both terminals with a metal object at the same time. Doing
so may cause an explosion or a fire.
m Do not install both old and new AA batteries; replace all 4
alkaline AA batteries at the same time to ensure optimum
battery life.
m Recharge only rechargeable battery packs, and follow
instructions carefully when recharging. Failing to do so may
cause a hazard.
