■ Switch on or off
To switch on, press and hold the power key until the speakerphone beeps
and the green indicator light turns on. The indicator light flashes when
the speakerphone tries to connect to a paired device. When the
speakerphone is connected to a paired device and is ready for use, the
blue indicator lights are displayed.
To switch off, press and hold the power key until all the indicator lights
turn off. If the speakerphone is not connected to a paired device within
about 5 minutes, it switches off automatically to save power.
