• Always make sure that the positive (+) and negative (–) poles of the batteries are oriented correctly.

• Use only the types of batteries specified for use with this unit.

• Charge the battery pack in an area where the temperature is between 10˚C (50˚F) and 35˚C (95˚F).

Charging in areas that are very cold or exposed to direct sunlight can cause deterioration and leaking

of the battery pack.

• To avoid deterioration and leaking, the battery pack is designed to discharge even when you do not

use the CASSIOPEIA. Be sure to recharge the battery pack at least once every three months, regard-

less of how much you use the CASSIOPEIA during that time.

• A battery pack that loses power too quickly after it is charged is probably near the end of its service life.

In such a case, you have to purchase a new battery pack.

4. Remove the main battery and then load a new battery pack.

• Make sure the battery pack is oriented correctly.

5. Replace the main battery cover.

6. Slide the battery cover switch to LOCK.

Replacing the Main Battery

1. Make sure your CASSIOPEIA is turned off.

• Press the [Power] button to turn off power.

2. Turn the CASSIOPEIA over.

3. Slide the battery cover switch to MAIN, and then remove the main battery cover.

Replacing the Back-up Battery

Important

• Never remove the main battery and back-up battery from the CASSIOPEIA at the same time. Doing so

causes all data stored in memory to be deleted.

• Should the main battery and the back-up battery both require replacement, be sure to always replace

the main battery first.

• Be sure to replace the back-up battery as soon as possible whenever the following message appears

on the display: “Prevent possible data loss by promptly replacing or recharging your back-up

battery according to your hardware manufacturer’s instructions”.
