Automatic Volume Control
The Sound ID 300 has built-in Automatic Volume Control. Your headset
will automatically adjust the volume based on the surrounding noise level.
The amount of volume increase or decrease is dependent on a number
of factors such as the PersonalSound
™
setting.
Advanced Options
The following advanced functions can can be controlled from most
phones, or from your headset as follows.
Call Mute: To activate or deactivate mute, briefly press the Main and
VPB buttons simultaneously. You will then hear either two falling tones
(mute) or two rising tones (unmute). You will hear a reminder beep once
every 30 seconds when a call is on mute. Most phones will also allow
you to mute a call from the handset if desired. In this case you must also
unmute the call from the phone.

and VPB buttons for approximately two seconds until you hear a beep.

the Main Button. The first caller will be placed on hold and the new call
will be answered.
To Swap Active Call and Held Call*: Press the Main and VPB buttons
for approximately two seconds until you hear a beep. If your handset does
not respond to this command, try pressing the Main button twice quickly.
