The transceiver automatically switches to Transmission Mode when the VOX circuitry
senses that you have begun speaking into the microphone.
1. When operating the VOX function, be sure to set the VOX Gain level which allows the
transceiver to recognize the sound levels.
2. If the microphone is too sensitive, the transceiver will begin transmitting when there is
noise in the background.
3. 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

Storage", receiving frequency, receiving QT. After reported frequency, If it did not report
the DQT and QT that indicating that the channel is not set QT, or continue to broadcast
DQT and QT , when broadcast frequency and QT, I "beep" sound that appears to indicate
"point. "After reporting the DQT "beep" sound occurs, expressed as a positive DQT, a
"beep, beep" twice, indicating that the reverse digital tone.
