Charge the battery
Before charging the battery, carefully
read “Battery and charger
information”.
1. Connect the charger to a wall
outlet.
ENGLISH
2. Connect the charger cable to the
charger connector. The red
indicator light is displayed during
charging.
Charging the battery fully may take
up to 1 hour. Charging the battery
with the AC-15 charger for 15
minutes provides up to 2 hours of
talk time.
3. When the battery is fully charged,
the green indicator light is
displayed.
Disconnect the charger from the
headset, then from the wall outlet.
This saves energy, as chargers
consume a small amount of power
when connected to a wall outlet,
even when not charging.
The fully charged battery has power
for up to 6 hours of talk time or up to
180 hours of standby time.
To check the battery charge when the
headset is not connected to a charger,
press the multifunction key when the
headset is connected to a mobile
device. If the indicator light is green,
the charge level is sufficient. If the
light is yellow, you may need to
recharge the battery soon. If the light
is red, recharge the battery.
When the battery charge is low, the
headset beeps every 5 minutes and
the red indicator light flashes.
