VOICE OPERATED TRANSMISSION (VOX)

VOX operation allows you to transmit hands-free. VOX can only be
used if you are using a supported clip microphone with earphone/
hanger. This function can be turned off for specifi c channels. To
activate VOX and set the VOX Gain level, perform the following
steps:
1 Connect the microphone with earphone/hanger to the transceiver.
• The VOX function does not activate when a microphone with
earphone/hanger is not connected to the accessory terminal of the
transceiver.
2 With the transceiver power OFF, press and hold the Up key
while turning the transceiver power ON.
• The LED indicator lights yellow and "VOX" and the channel number
are announced.
3 Press the PF-1 key to select the VOX Gain level of the radio
(from 1 ~ 5 or Off).
• The transceiver will announce the VOX Gain level. If the VOX Gain
level is Off, a double beep sounds.
• Press the PF-2 key to enable or disable the VOX function for the
current channel (you can change this setting for each channel by
selecting a channel with the Up/Down keys). When VOX is turned
ON, a beep sounds. When it is turned OFF, a double beep sounds.
4 While adjusting the level, speak into the microphone to test the
sensitivity level. When sound is recognized, the LED lights red.
5 Press and hold the PTT switch for 3 seconds to save the setting.

◆ VOX Gain level 1 is the least sensitive and VOX Gain level 5 is
the most sensitive.

VOX function is enabled, battery save mode will be disabled.
◆ If a microphone with earphone/hanger is connected to the
transceiver while the VOX function is switched ON and the VOX
Gain level is confi gured to a higher, more sensitive level, louder
received signals may cause the transceiver to start transmitting.
