1  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.

6  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.

8  I recently purchased a Retevis 2 Pin PTT Mic Covert Acoustic Tube In-ear Air Acoustic Earpiece Headset off Amazon for work (were use Retevis H777 radios) but when I tried it, my audio can BARELY be heard. The sound can be heard up to the point until it connects to the acoustic tube, at which point I can hear hardly anything. I really like the style and comfort of this earpiece. What could be the problem?
This is may be the quality problems , please send mails to your Amazon sellers to ask for your warranty .
9  I just purchased 20 H-777 radios, to add to the already 30 I have. Of the 20 new ones, only three would open into programming mode. I have 17 little bricks that I can't program. I'm using the cable you provided, along with the same computer and software that I used on the other 30 H-777 radios. I'm using the same programming steps as the other 30, yet only 3 of the new ones would receive the new program flash. Do I need to return these? I need another 50 next year, so I'm hoping there is a simple solution.
