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
Press and hold the PTT switch for 3 seconds to save the setting.
• A beep will sound.
5 Turn the transceiver power OFF and then ON again to
activate VOX.
Note:
◆ The transceiver will automatically return to normal operation if
no action is performed for 20 seconds.
◆ VOX Gain level 1 is the least sensitive and VOX Gain level 5 is
the most sensitive.
◆ When the
microphone with earphone/hanger
is inserted and the
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.
