VOX GAIN
To enjoy the VOX function, take the time to properly adjust the VOX Gain level.
This level controls the VOX circuit to detect the presence or absence of your
voice.
There are 2 ways to adjust the VOX Gain.
While the VOX function is ON:
1 Speak into the headset microphone using your normal tone of voice to
transmit.
• If transmitting does not begin, readjust the VOX Gain so that the transceiver
transmits while you are speaking. To readjust the gain, press and hold [PTT] then
rotate the ENC control to select a more sensitive gain level.
• While readjusting the gain, you can release [PTT]. The transceiver will remain in
Adjustment Mode for approximately 5 seconds.
2 Adjust the VOX Gain by rotating the ENC control until the transceiver reliably
switches to transmit mode each time you speak.
From the Menu:
1 Enter Menu mode and access Menu No. 16 (VOX), then press [F].
2 Rotate the ENC control to select the desired VOX gain level from 1 (least
sensitive) to 9 (most sensitive), then press [F] to store the setting.
3 Press [MENU] or [PTT] to exit Menu mode.
VOX ON BUSY
You can configure the transceiver to force VOX to transmit even if the transceiver
is receiving a signal.
1 Enter Menu mode and access Menu No. 17 (VOX.BSY), then press [F].
2 Rotate the ENC control to select "ON", then press [F] to store the setting.
3 Press [MENU] or [PTT] to exit Menu mode.
Note: You can press [PTT] or [PF] (if 1750 Hz is programmed) to transmit, regardless of the
setting in Menu No. 17.
VOX DELAY TIME
If the transceiver returns to receive mode too quickly after you stop speaking, the
end of your signal may not be transmitted. To avoid this, select an appropriate
delay time that allows your entire signal to be transmitted, before Transmit mode
ends. However, do not make the delay overly long.
1 Enter Menu mode and access Menu No. 18 (VOX.DLY), then press [F].
