The CLS1110 is a one channel radio
. However the one channel can be changed to another frequency and/or PL code. With the radio turned OFF, hold in the PTT and the MON, while turning the radio on. Continue to hold the PTT and MON until the radio stops making noise. You are then in programming mode and can use the menu button to walk through the stages of programming. Use the PTT to change the settings, and the MENU to lock it in.
