Low battery warning
If you are on a call and the headset battery is critically low, you will hear a repeated single
low tone every 15 seconds indicating that the battery is low. You should recharge the headset
immediately.
If you are not on a call and press the call control button, you will hear three low tones if the
battery is critically low. You should recharge the headset immediately.
Muting your headset during a call
To mute/unmute the call, press the volume button down – for 1.5 seconds.
When mute is activated, the Call/mute LED on the base will be solid red and you will hear three
high tones (you will still be able to hear the caller).
Adjusting your headset volume
Fine-tune your headset volume by pressing the volume [+] button to increase or the volume [–]
button to decrease.
Make set up volume adjustments for the desk phone with the base volume dials.
Out of range warning tones
If you are on a call and go out of the operating range, you will hear three low tones. You will
hear a single mid tone when you are back in range.
If you stay out of range, an active call will be suspended. The call will be re-established when
you walk back into range. If you remain out of range for more than 5 minutes, the system will
drop the call.
If you are not on a call and go out of the operating range and then press the call control button,
you will hear a single tone for the button press and three low tones for the failure to make a
link.
