Checking the remaining battery charge
You can check the remaining battery charge of the rechargeable batteries of the headset and the charging case.
When you remove the headset from the charging case
When you remove the headset from the charging case, the voice guidance indicating the remaining battery charge of the headset can be heard via the left and right units of the headset respectively.
“Battery about XX %” (The “XX” value indicates the approximate remaining charge.)
“Battery fully charged”
The remaining battery charge indicated by the voice guidance may differ from the actual remaining charge in some cases. Please use it as a rough estimate.
When the remaining charge becomes low
If a warning beep sounds and the voice guidance says, “Low battery, please recharge headset”, charge the headset as soon as possible.
When the battery becomes completely empty, a warning beep sounds, the voice guidance says, “Please recharge headset. Power off”, and the headset automatically turns off.
When you are using iPhone or iPod touch
When the headset is connected to an iPhone or iPod touch over an HFP Bluetooth connection, it will show an icon that indicates the remaining battery charge of the headset on the screen of the iPhone or iPod touch.

B: 100% - 70%
C: 70% - 50%
D: 50% - 20%

Checking the remaining battery charge of the charging case
When you set the headset into the charging case or remove the headset from the charging case, if the indicator (red) on the charging case flashes slowly, the remaining battery charge of the charging case is 30% or lower. Charge the charging case.
Note
- The remaining battery charge may not be properly displayed if the headset has not been used for a long time. In this case, repeatedly charge and discharge the battery multiple times to properly display the remaining battery charge.
