POWER
indicator
To recharge the headphone battery after use
Place the headphones on the transmitter 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 transmitter after charging has
completed.
Notes
• The transmitter 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 transmitter. If a contact pin becomes dirty, charging may
not be possible.
• Charging may not be completed if the transmitter’s contact pin and headphones’ contact point
are dusty. Wipe them with a cotton bud, etc.

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.
