Battery warnings
The MessagePad displays a warning when the battery level is
low.
When you first see the warning, you have less than an hour
of power left in your main batteries.
If you don’t change the batteries in time, the MessagePad
turns itself off automatically to save the information in its
memory. You can turn the MessagePad back on once you’ve
replaced the batteries or plugged in a power adapter.
The MessagePad displays a similar warning when the backup
battery level is low.
Batteries—rechargeable
You can use a rechargeable battery pack instead of alkaline
batteries. Use only the battery pack designed for your
MessagePad. Follow the instructions that come with the
battery pack.
If you buy a rechargeable battery pack, you also need a
power adapter or a charging station.
When the MessagePad is plugged in, the battery pack
recharges automatically. You can use the charging station to
recharge two battery packs at the same time (one in the
MessagePad and another in the charging station). See the
instructions that come with the charging station.

Appendix A
Important Do not use individual rechargeable batteries in
your MessagePad. The battery level indicator is not calibrated
for that type of battery and may drain too much power from
the batteries, reducing their ability to stay charged.
Replacing batteries
Warning Never take out both the main batteries and the
backup battery at the same time. If you do, the MessagePad
will lose information that it needs to operate properly.
Replacing the main batteries
Warning
When replacing the main batteries:
m Make sure each battery’s + and – ends are in the correct
position. Follow the diagram in the battery holder or battery
compartment. If you install batteries the wrong way, the
batteries may leak and damage your MessagePad. Leaking
batteries may be hazardous and any damage caused by
leaking batteries is not covered by your warranty.
m Replace all the main batteries at the same time. Don’t mix
old and new batteries.
m Install only alkaline batteries or a rechargeable battery pack
designed specifically for your MessagePad.
Warning Do not use individual rechargeable nickel-
cadmium (NiCd) batteries. The battery level indicator is not
calibrated for that type of battery.
