Charging the Headset
The Headset has a rechargeable battery. Before using the Headset for the first time, you have to charge the Headset battery for approximately two hours in order to get a full charge. A fully charged battery provides up to seven hours of talk time and over one week of standby time. When the battery is low, the LED indicator flashes red. The low-battery-warning indication will begin three minutes of talk time before the Headset runs out of power. You can recharge the Headset at any time without waiting for the battery to be completely discharged. To keep the battery in good condition, always recharge the Headset within a month once it is fully discharged. Before charging, make sure that the Headset is at room temperature. The battery will not charge in very cold or very hot conditions.
NOTE: The Headset battery is not replaceable.
