Notes on Batteries
• 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
Pull up the self-adjusting band and check the
power indicator located on the upper part of the
right housing. The batteries are still serviceable
when the indicator lights in red.
Charge the rechargeable batteries or install new
dry batteries if the power indicator light dims,
flashes, or the sound becomes distorted or noisy.
Note
The rechargeable nickel-metal hydride batteries should
be replaced with new ones when they last only half the
expected time after a proper recharging. The
rechargeable batteries type BP-HP550 are not
commercially available. You can order the batteries from
the store where you purchased this system, or at your
nearest Sony dealer.
