22  I just opened the 10 Retevis H-777 units that I ordered last year. Of the 10 units I ordered, only 2 had the ear piece units inside the boxes. There were clips in a few of the units to attach the handsets, but of the 10 units, only 4 of them had the attachment clips. How can I get the missing parts that should have come with my purchase? Than you for your help! Perry
please tell me your radio model,I will cc and contacted after-sale service, they will check and reply to you a.s.a.p., thanks for your patient waiting...
23  hi can you let me know if there is an upgrade for this radio so you can use slot 2 thanks in advance peter
Could you explain the sentence“so you can use slot 2 ”Thanks
24  Hi All, Thanks for the response, but I don't think we're on the same page / understanding each other correctly. Yes - The RT1 has longer range / distance..... but unfortunately the RT1 does not solve the problem (which is a common problem and needs to be explained on your site). Question Rephrased: The Problem : There is something obstructing communication between two points (Hill / Mountain / Could be anything). Solution = Repeaters???: I want to place 2 x repeaters at highest point on hill to relay the message from one side of hill to the other side (This is why repeaters were developed right?). Questions: A) Does your repeater work with the H-777 Radios?. B) Repeater Power Source: Does it have it's own build in battery? (i.e. can I link repeater to a solar panel on top of hill to charge battery during day.... the battery will last overnight?).... or do I need to have my own separate battery?. C) How does the repeater relay the message? i.e. I'm on channel 1
Hello James I'm consulting our engineer about your questions, then reply you by email later,please notice check it Brgds
25  Hello, I bought 2x H777 and tried a couple of hours to sent a 1750Hz tone to open our repeater. As described we have to press the MONI button after activating the PTT. What parameters do I have to enter via the software?? Thanks in advance Uwe
Please note: H777 frequency range is 400-470MHz, 1750MHz beyond the range
26  I just purchased a 10 pk of the H-777 radios. We set them up like we normally set up our two way radios. We are unable to get any transmissions at all. Will these radios work with other radio types ( such as motorolla) We followed the small booklet that comes with these radios but nothing is working. Your help would be greatly appreciated.
1.Just switch them to the same channel,please make sure two radios frequency and CTCSS is same,then try again Finished above steps, need prepare for work You need a H777 programming cable C9018A:http://www.retevis.com/2-pin-programming-cable-for-revevis-h777-baofeng-kenwood then download H777 usb driver and H777 software from Retevis official website: http://www.retevis.com/resources-center/ Attached a pic for you reference:
27  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 .
28  How do I program my new H-777 walkie talkie and is it necessary to do so? The squelch volume is too loud when interference is taking place. How do I adjust the volume?
You need to connect your radio to PC by cable , How to program it on software please read the guide here : http://blog.retevis.com/retevis-radio-frequency-programming/ . Then when you open the software , you will see just like the picture below -- There you could find the squelch levels , that's the function you need to set .And please note --
1. The higher the number is , and the stronger the ability of noise suppression is . But meanwhile it has less probability to receive the weak signal.
2. Conversely, The smaller the number is , the weaker the ability of noise suppression is , But meanwhile it is more easily to receive the weak signal.
3. A "0" level indicates that there is no squelch suppression function, which is the lowest level.
29  Do I need to down load disc to each one I have a set of 6 RT-5R 2 way radio's?
If you gonna program frequency on software , just download the USB Driver and Software on our official website is ok -- http://www.retevis.com/resources-center/

30  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 .
