I just got two V1 units set up on our local repeater using the keypad/menu. First take a look at the owners manual and find your repeater frequency and select the REPT channel that corresponds to it. They are pre-programmed, channels 15-22. If you have the Tone in and Tone out requirements for your repeater, go into the menu and scroll to T CTCSS and R CTCSS respectively and select from the pre-programmed frequencies. Good luck Dave WRJS228
