  1. Okay I was able to setup our walkies to scan channel one. But it only works if you are on Chanel two. If you change to Chanel 3-16 it doesn’t work. Any help would be amazing!

    1. Hello Arron;
      1,add scan function to the channel you want to scan,and setup the side key Monitor function. also √ before the scan function
      2,set all the channel with out CTCSS/DCS.(If you add CTCSS, the scan won’t work)
      3,turn off the radio, turn to 16 channel, then held the monitor button & PTT button, turn on the radio. you will hear “on” “power on” then it will begin to scan.and the light will be flash yellow,
      4,when scan to the frequency someone talking, you could hear it and talk to him. if stop talking , after 5 seconds, then H777 will go on scanning.
      thanks
