Charge the battery
The headset has an internal,
nonremovable, rechargeable battery.
Do not attempt to remove the battery
from the headset, as you may damage
the headset.
1. Connect the charger to a wall
outlet.
2. Connect the charger cable to the
headset (8). The red indicator light
is on while charging. It may take a
while before charging starts. If
charging does not start, disconnect
the charger, plug it in again, and
retry. Charging the battery fully
may take up to 2 hours.
3. When the battery is fully charged,
the indicator light turns off.
Disconnect the charger from the
headset and the wall outlet.
The fully charged battery has power
for up to 5 hours of talk-time or up to
150 hours of standby time. However,
the talk and standby times may vary
when used with different mobile
phones or other compatible Bluetooth
devices, usage settings, usage styles,
and environments.
When battery power is low, the
headset beeps, and the red indicator
light starts to flash.
