Checking the remaining battery power of the headphones

• When the headphones sound a long beep (about 2 seconds) and turn off.

• The power indicator [Details] of the headphones is dim or does not light up.

• [Charge Level Low] is displayed at [Headphones] on the Status screen.

• If you do not use the headphones for a long period of time, the life of the rechargeable battery may become short. The life of the rechargeable battery improves when you repeat the charging and discharging process several times.

• If you store the headphones for more than a year, charge the battery once a year to prevent over-discharge.

• If the length of time you can use the headphones became extremely short, the rechargeable battery should be replaced with a new one. Please contact your nearest Sony dealer for a battery replacement.
