Notes on Battery

•Do not charge a dry battery.

•Do not carry a dry battery together with coins or other metallic objects. It can generate heat if the positive and negative terminals of the battery accidentally come into contact with metallic objects.

•If you are not going to use the unit for a long time, remove the battery to avoid damage from battery leakage or corrosion.

Checking the remaining battery power

Check that the power indicator turns on and off each time you press the POWER button. The battery is still serviceable when the indicator lights in red.

Charge the rechargeable battery or install a new dry battery if the power indicator dims, flashes, or does not light up, or the sound becomes distorted or noisy.

Note

The rechargeable nickel-metal hydride battery should be replaced with new one when it lasts only half the expected time after a proper recharging. The rechargeable battery type BP-HP550 is not commercially available. You can order the battery from the store where you purchased this system, or at your nearest Sony dealer.
