CDM 1550 lights not working at all
hey guys, so i couldnt figure this issue out yet. i have a cdm 1550 and all the lights are out; scan light, channel busy light, open monitor, and all the green background light! im using remote head and i tested it with another radio, it works perfect! all the lights and everything come up. but as soon as i hook it up to the other radio, none of the lights work! using the same flex and cables and... so i dont think its a flex issue! i appreciate it if anyone has any comment?
