the AC-6 charger for 15 minutes 
provides up to 5 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. Push the cover over the 
charger connector.

To charge the headset with a 
compatible Nokia charger that has a 
2.0 or 3.5 mm charger plug, use the 
Nokia Charger Adapter CA-146C (sold 
separately).

To charge the battery through the USB 
port of a compatible PC, connect one 
end of the Nokia Connectivity Cable 
CA-101 (sold separately) to the 
charger connector and the other end 
to the USB port.

The fully charged battery has power 
for up to 8 hours of talk time or up to 
160 hours of standby time.

To check the battery charge when the 
headset is not connected to a charger, 
press the power key when the headset 
is switched on. 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.

To switch on, press and hold the power 
key for about 2 seconds. The headset 
beeps, and the green indicator light is 
displayed. The headset tries to 
connect to one or two last connected 
devices. When the headset is 
connected to a device and is ready for 
use, the blue indicator light flashes 
slowly. If the headset has not been 
paired with a device, it automatically 
enters pairing mode.
