ready to use when battery is charged – just plug in dongle.
Press the key on the dongle for 4 seconds, then place
the headset in its charger. The dongle‘s red LED dou-
ble-flashes rapidly and turns off when the registration
has been successful, while the headset‘s LED shows

mode. After 4 seconds the red LED starts to double-flash; after 10
seconds the LED starts to flash red rapidly, indicating that the dongle
has entered deregistration mode.
2. Release the key and press it again for 1 second to confirm deregistra-
tion. The LED turns green for three seconds, turns off for one second
and then shows steady red light.
