POWER
indicator
To recharge the headphone battery after use
Place the headphones on the processor after use. The CHG indicator lights up, and the
RF indicator goes off, and then charging starts.
Since the built-in timer recognizes when charging is complete (approx. 3 hours), there
is no need to remove the headphones from the processor after charging has
completed.
Notes
• The processor automatically turns off while charging the battery.
• This system is designed to charge only the supplied rechargeable battery, type BP-HP2000, for
safety. Note that other types of rechargeable batteries cannot be charged with this system.
• If dry batteries are installed, they cannot be charged.
• Do not attempt to use the supplied BP-HP2000 rechargeable battery with other components. It
is for use with this system only.
• Charge in an environmental temperature of between 0˚C and 40˚C (between 32˚F and 104˚F).
Otherwise, the battery may not be fully charged.
• Do not touch the contact pin of the processor. If a contact pin becomes dirty, charging may not
be possible.
• Charging may not be completed if the processor’s contact pin and headphones’ contact point
are dusty. Wipe them with a cotton bud, etc.

Checking the battery power
Pull up the self-adjusting band and check the POWER
indicator located on the right housing. The battery is
still usable when the indicator lights blue.
Charge the rechargeable battery or install new alkaline
batteries if the POWER indicator does not light up.
Note
The rechargeable nickel-metal hydride battery should be replaced with a new one when it lasts
only half the expected time, after a full charge has been performed. The rechargeable battery,
type BP-HP2000, is not commercially available. You can order the battery from the store where
you purchased this system, or at your nearest Sony dealer.
