Thetransceiver automatically switches to transmit when theVOX circuitry senses that you have begun speaking intothe microphone.When using VOX, develop the habit of pausing betweenthoughts to let the transceiver drop back to receivebriefly. You will then hear if anybody wants to interrupt,plus you will have a short period to gather your thoughtsbefore speaking again. Your listener will appreciateyour consideration as well as respect your morearticulate conversation.VOX can be switched ON and OFF independently forCW and the other modes excluding FSK.Press [VOX] to toggle VOX between ON and OFF.• “VOX” appears when the function is ON.n Microphone Input LevelTo enjoy the VOX function, take time to set the gainof the VOX circuit to the correct level.
