47  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 .
48  Can not get H 777 software to install on system. windows 10
I'm sorry but could you try it on win8 please ?
49  I have not used the radio for some months and the battery was completely dead. I placed the radio (switched off) and the LED light was green. I was confused as I believed it should be red for charging and only show green when fully charged! I removed the battery from the body of the radio and reattached it and placed the set in the charging cradle - same result, a green light. I then turned the radio on while still placed in the charging cradle and the green light immediately turned red. I am assuming that this suggests a fault. Can you advise please. Thanks Roger
Did you try charge the battery only ? If it is still not ok ,please contact your seller to ask for your warranty .
