    Why is my Entel Transceiver transmitting without pressing the PTT button?

      Kevin ColeAug 1, 2025
      If your Entel Transceiver transmits without pressing the PTT button, it's likely that VOX has been enabled. To disable it, hold the MEM button for 2 seconds, then use the UP or DOWN button to select “off”.

      Christina PhillipsAug 16, 2025
      If the scan key on your Entel Transceiver does not start the scan, it could be due to a couple of reasons. Either no channels are memorized (MEM), or the squelch is not adjusted properly. Use the MEM key to enter the desired channels into the scan memory. Also, adjust the squelch to the threshold or to the point where the white noise just disappears.
