Note that the voice transmission via VOX is the same as holding down PTT in that
the radio will also give a tone for available communication. During transmission, if no
voice is detected, the radio will start VOX Hold Time counting. If the time is over
without any voice detected, the transmission will terminate and the radio will enter
the Call Hang Time.
When the radio is in use, its speaker will play such sound as tones and the received
voice. These sounds may also be detected when VOX is active. To prevent
transmitting such sounds, the radio will automatically disable the microphone
detection when the speaker is on and enable it again when the speaker is off.
When in auto transmission such as the hot microphone on for an emergency alarm
or remote monitor, the radio will disable VOX.
VOX is a feature associated with the current channel and will not affect other
channels. The VOX feature can be enabled/disabled through the following three
methods:
Radio menu;
Programmable key;
CPS.
When using PTT, the VOX will be paused, but the feature on the current channel is
still active, no matter whether the radio is switched to other channel or rebooted.
