•If you are not going to use this player for a long time, be sure to disconnect the power supply (AC power adaptor, dry battery, or rechargeable battery). To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord.

On charging

•Be sure to use the supplied battery charger.

•Charging time may vary depending on the battery condition.

•When you use the battery for the first time or after a long period of disuse, the battery life may be shorter. In this case, charge and discharge the battery several times. The battery life will be restored.

•If the rechargeable battery capacity becomes half the normal life, replace it with a new one.

•Remove the rechargeable battery when the unit is not to be used for a long time. Do not carry the rechargeable battery in your pocket or a bag, etc., with metallic objects such as key rings.

precautions:

•Install batteries with the + and – poles aligned correctly.

•Do not try to recharge dry batteries.

•When the player is not to be used for a long time, be sure to remove the batteries.

•If a battery leak should develop, carefully and thoroughly wipe away battery fluid from the battery compartment before inserting new ones.

•Do not carry the dry battery in your pocket or a bag, etc., with metallic objects such as key rings. The terminals of the battery or the battery carrying case may heat up from a short-circuit and can be dangerous.
