A voice message confirms the new setting each time you press a button.

The volume levels on all active volume steps can be increased by +6 dB. For instance, this function can be used to
compensate for additional attenuation from simultaneous use of ear-plugs and headset.

A voice confirmation "EXTRA HIGH VOLUME" is given when you have activated the function.
WARNING: High sound pressure!
Last used setting remains between sessions!
g Press the [–] button for 10 seconds to deactivate VOLUME BOOST.
A voice confirmation "NORMAL VOLUME" is given when you have deactivated the function.
2.5.1.2 VOX (Voice operated transmission)
In simplex radio communication, VOX normally means that reception of the incoming sound from the receiver is completely
stopped when sound of a certain level reaches the microphone and switches the radio to transmission mode.
With the full duplex DECT-Com II units, VOX means "a voice operated noise gate", which can prevent from transmitting
background noise up to a certain sound level from units where the user do not speak, but can constantly, all the time, listen
to the incoming sound from the conference.
g In VOX MODE, use the [+] and [–] buttons to set the VOX sensitivity.
There are 7 VOX settings; "OPEN – 1 – 2 – 3 – 4 – 5 – OFF", where OPEN means constantly transmitting (continuous full
duplex) and OFF means that you have to use a [PTT#] button to transmit (see 2.5.2 PTT).
A voice message indicates your selected choice.
Last used setting is remembered between sessions.
IMPORTANT: If you are using a Peltor headset which has a microphone with ambient-noise compensation, always position
the microphone very close to your lips (max. 3 millimetres) for optimal VOX function!
