1  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 .
2  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 .

5  Ho acquistato 2 settimane fa, su ebay 4 radio retevis rt31 una PMR 8ch e 99 codici CTCSS vorrei sapere come fare per avere la tabella dei 99 CODICI CTCSS oppure dove trovarla. In attesa grazie per l'attenzione Luca

6  I have an RT3 with the latest firmware download on it (3.32). It is not saving the color codes or repeater slots when I manually program or if I use the software to program it. I can go into the settings for color code as one example and one time it will show "3" then next time it will show "0". The behavior is erratic making it difficult to tell if I have the radio programmed correctly or not. Any suggestions?
We're contacting with our technician, will reply you as soon as possible, thanks for you understanding
7  Trying to program RT6 with chirp and it says "Error reading data from radio: not the amount of data we want". any ideas?
RT6 has special Connect-Port design , could you please check if it is because of Poor contact ? Also RT6 use its own special programming cable , Please make sure if you use the right one ?
8  if I set the channels 1-8 to the frequency for PMR channels and don't set any CTCSS/DCS will they transmit and receive on all the CTCSS/DCS frequencies on the selected channel or do I have to put them into search mode to find the frequency another radio is operating on IE My radio is on channel 8 (no CTCSS/DCS) and my collegue is on Channel 8-1 CTCSS/DCS will they work together or doI have todo something to 'find' him hope that makes sense Many thanks
If you don't set CTCSS/DCS and your collegue set it (Under the same frequencies ) , the you could receive your collegue 's signal , but you can not transmit the signal to him . Just set same CTCSS/DCS and same frequencies could work with each other .
9  need any license to use this h777 model in India?
Anyway people that from India bought H777 before . And they don't feedback anything bad to us .
