Replacing The Battery - Casio EW-B100C User Manual

Replacing the Battery

Replace the battery as soon as possible after the message "The
battery is low." appears on the display.
You should replace the battery at least once a year, even if this
message does not appear.
A nickel-metal hydride battery (rechargeable battery)
in particular can deteriorate when left in the electronic
dictionary when you are not using it for long periods. Remove
the rechargeable battery as soon as possible.
•
Make sure you turn off power before replacing the battery.
Changing the battery while power is on can cause history data,
settings, and other information to be deleted.
• Always replace the battery with a new AA-size alkaline battery or a fully
charged AA-size nickel-metal hydride battery (rechargeable battery).
Using a battery other than those specifi ed can greatly shorten battery
life and cause abnormal operation.
• When changing to a rechargeable battery, be sure to change the
battery type setting to "Ni-MH (Rechargeable)".
