Checking the remaining battery charge
You can check the remaining battery charge of the rechargeable battery.
When you press the (power) button while the headset is on, a voice guidance indicating the remaining battery
charge can be heard.
“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.
In addition, the indicator (red) flashes for about 15 seconds if the remaining battery charge is 10% or lower when the
headset is turned on.
When the remaining charge becomes low
A warning beep sounds and the color of the operating indicator (blue) becomes red. If you hear the voice guidance say,
“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.
