Low Battery Warning
If you are on a call and the headset battery is critically low, you will hear a repeated single
low tone every 15 seconds indicating that the battery is low. You should recharge the headset
immediately.

battery is critically low. You should recharge the headset immediately.

reattached within 5 minutes. This allows for unlimited talk time.

2 Remove the charged battery from the second battery charger and slide it onto the headset
until you hear a click.
3 Charge the used battery by inserting it in the second battery charger.
