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.
