VOICE OPERATED TRANSMISSION (VOX)

VOX (VOX/ Semi-VOX) operation allows you to transmit hands-free. This feature
can be enabled by your dealer. To operate VOX, you must use an optional
headset.

VOX Type

VOX: When the voice level to the microphone is higher than the reference level
(VOX Gain Level), the transceiver automatically starts transmission.
Semi-VOX: Transmission is started by pressing the PTT switch or the button
programmed as [Second PTT], and transmission continues while speaking, even
