Saving a favorite number
It is possible to save a favorite number in the headset and
speed dial it with the multi-function button. This number can
be automatically saved from the last incoming call number
(not compatible for hidden or unidentified call numbers).
To save a favorite number from the last incoming call:
• Once the received call has ended, press and hold both
the Vol+ and Vol– buttons for three seconds, until you
hear a series of tones. The number from the last received
call is stored.
To call the favorite number:
• Press and hold the multi-function button for one second.
Identifying the favorite calling number
When the mobile phone rings, if the calling number is
already stored as a favorite number, a special tone sounds
identifying the favorite number call.
Note: Saving a favorite number and caller identification do
not work if the calling number is hidden or unidentified by
the network.
Conserving battery life
To conserve battery life, your headset features an auto-sleep
function. This function turns the headset off after 12 hours of
inaction. Once your headset has entered auto-sleep, it can be
switched on again normally.
When the battery has only 10% charge remaining, the
headset produces an audible warning tone sequence every
time a call is ended.
To check your battery level:
Press the multi-function button [1] four times.
