Important

Be sure to observe the following important battery handling precautions. Failure to do so can cause batteries to leak, resulting in damage to surrounding items and create the danger of fire and electrical shock.

•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, regardless 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.

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.
