displayed. Charging the battery fully may take up to 2 hours and 10 
minutes.

If you use a charger that is connected to the cigarette lighter socket, 
power must be supplied by a 12-volt car battery. Ensure that the 
charger is properly inserted in the cigarette lighter socket and does 
not interfere with the normal operation of the car.

In some car models, the cigarette lighter socket is powered by the car 
battery even when you remove the ignition key. In those cases, the 
car battery might be discharged even if the speakerphone is not in 
use. For more information, contact the vehicle manufacturer.

Disconnect the charger from the speakerphone, then from the power 
source.

The fully charged battery has power for up to 24 hours of talk time or up 
to 80 days of standby time.

When the battery charge is low, the red indicator light flashes slowly 
and the speakerphone beeps about every 5 minutes. Recharge the 
battery.

To switch on, press the power key. The speakerphone plays an ascending 
sequence of beeps, and the green indicator light flashes once. The 
speakerphone tries to connect to the device that was last connected to 
it.

When the speakerphone is connected to your device and ready for use, 
the green indicator light flashes slowly.

To switch off, press and hold the power key for about 2 seconds. The 
speakerphone plays a descending sequence of beeps, and the red 
indicator light flashes once.
