Replacing Batteries

Replace batteries as soon as possible after the message “The

batteries are low.” appears on the display.

You should replace batteries at least once a year, even if this

message does not appear.

Nickel-metal hydride batteries (rechargeable batteries)

in particular can deteriorate when left in the electronic

dictionary when you are not using it for long periods. Remove

rechargeable batteries as soon as possible.

Make sure you turn off power before replacing batteries. Changing

batteries while power is on can cause history data, settings, and other

information to be deleted.

Always replace both of the batteries with two new AA-size alkaline

batteries, or two fully charged AA-size nickel-metal hydride batteries

(rechargeable batteries). Using batteries other than those speciﬁ ed and

mixing old batteries with new ones can greatly shorten battery life and

cause abnormal operation.

When changing to rechargeable batteries, be sure to change the

battery type setting to “Ni-MH (Rechargeable)”.

Battery Precautions

Using batteries incorrectly can cause them to burst or leak, possibly

damaging the interior of the unit. Note the following precautions:

Be sure that the positive (+) and negative (–)

ends of each battery are facing in the correct

directions.

Never mix batteries of different types.
