52  Hello, got a set of 10 Retivis H77 radios for our company. For some reason, one of the radios seems to have lost the channel sequence. When the radio is turned on, the channel knob starts on channels 10,15,3,13,5,6,16,9,10,2,7,9,1,15,16 , How can this be set to original factory specs?
This is the switch on the curcuit board broken . Please find your seller to ask your warranty .

Anyway people that from India bought H777 before . And they don't feedback anything bad to us .
