VOX circuitry detects no voiced sound for 0.7 sec, it shuts off the transmission and makes the radio
return to Receive/Stand-by status.
Caution:
When the radio is engaged in Transmit status, you can hear a short “Pip!” via a speaker
of Headgear or Ear Mic. Remember that your transmission is not completed if no “Pip!” tone is
heard.
In this case, release the PTT Button (in PTT operation) or mute your speech more than 0.7 sec (in
VOX operation) to make the radio return in Receive/Stand-by status, and retry to press the PTT
Button or start speaking for establishing the transmission. Especially in VOX operation, you
should always aware of “Pip!” tone for starting speech and “Pip! Pip!” tone for ending the
transmission.
