VOX OPERATION

VOX can be activated or deactivated by your dealer.

VOX operation allows you to transmit hands-free. This feature can only be used if you are using a supported headset.

When operating VOX, you must set a VOX Gain level. This setting allows the transceiver to recognize sound levels. If the microphone is too sensitive, it will begin transmitting when there is noise in the background. If it is not sensitive enough, it will not pick up your voice when you begin speaking. Be sure to adjust the VOX Gain level to an appropriate sensitivity to allow smooth transmission.

To activate VOX and set the VOX Gain level, perform the following steps:

1

Connect the headset to the transceiver.

• The VOX function does not activate when a headset is not connected to the accessory terminal of the transceiver.

2

With the transceiver power OFF, press and hold the Side 1 key for 2 seconds while turning the transceiver power ON.

• The LED flashes red and green.

3

Press the Side 1 key to increase the VOX Gain level and the Side 2 key to decrease the level.

• The VOX Gain can be adjusted from levels 1 to 10 and OFF.

4

While adjusting the gain level, speak into the headset microphone as you would while under normal operation, to test the sensitivity level.

• When the microphone recognizes a sound, the LED lights orange. This allows you to determine a suitable level where background noise will not activate VOX operation while speaking into the microphone will.

• The transceiver does not transmit your voice during this test procedure.

Turn the transceiver power OFF and then ON again to save the setting and activate VOX.

To turn VOX operation OFF, enter the VOX Gain level setting

(step 2, above) and press the PTT switch, then turn the transceiver power OFF and then ON again.

Note:

◆ If a speaker/ microphone 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 transmission.

◆ When you operate the VOX function, you must use an optional

KHS-1 or KHS-2 accessory.
