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 specific 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. • A beep will sound. 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 configured to a higher, more sensitive level, louder received signals may cause the transceiver to start transmitting. 21
