Notes on Batteries
• Do not charge a dry battery.
• Do not carry a battery together with coins or metallic objects. Heat can be generated by the
battery if its positive and negative terminals are accidentally shorted.
• When you are not going to use the unit for a long time, remove the batteries to avoid damage
from battery leakage or corrosion.
See “Checking the remaining battery power” for details about checking the remaining
battery power.
Checking the remaining battery power
Pull up the self-adjusting band and check the
POWER indicator located on the right housing. The
batteries are still serviceable when the indicator
lights red.
Charge the rechargeable batteries or install new
alkaline batteries if the POWER indicator light dims,
flashes, or the sound becomes distorted or
intermittent.
Note
The rechargeable nickel-metal hydride batteries should be replaced with new ones when they
last only half the expected time, after a full charge has been performed. 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.
