Charging the headset when you are outside

A rechargeable battery is built into the charging case. If you charge the charging case in advance, you can use it to
charge the headset when you go out without a power supply.
If the charging case is fully charged, you can fully charge both the left and right units of the headset once at the same
time.
Notes on charging the headset when you are outside
When the headset is placed in the charging case, if the indicator (red) on the charging case flashes slowly, the
remaining battery charge of the charging case is low. Charge the charging case.
If the indicator (red) on the charging case does not turn on even when the headset is placed in the charging case, the
battery charge of the charging case is empty. Charge the charging case.

the headset, registering or connecting to Bluetooth devices, and music playback cannot be performed.
The headset cannot be charged when the computer goes into standby (sleep) or hibernation mode. In this case, change the
computer settings, and start charging the headset once again.
If the headset is not used for a long time, the rechargeable battery usage hours may be reduced. However, the battery life will
improve after a few recharges. If you store the headset for a long time, charge the battery to its full capacity once every 6 months
to avoid over-discharge.
If the headset is not used for a long time, it may take longer to charge the battery.
If the headset or the charging case detects a problem while charging due to the following causes, the indicator (red) of the
charging case flashes. In this case, charge once again within the charging temperature range. If the problem persists, consult
your nearest Sony dealer.

There is a problem with the rechargeable battery.
It is recommended to charge in a place with an ambient temperature between 15 °C and 35 °C (59 °F - 95 °F). Efficient charging
may not be possible beyond this range.
If the headset is not used for a long time, the indicator (red) on the headset or the charging case may not immediately light up
when charging. Please wait a moment until the indicator (red) lights up.
If the usage hours of the built-in rechargeable battery decrease significantly, the battery should be replaced. Consult your nearest
Sony dealer to replace the rechargeable battery.
