sounds).

(from 1~10 or Off).
• Press the Side 2 key to enable or disable the VOX function for

the most sensitive.
◆ If a headset 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 transmission.
