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?

2  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.

3  I need instructions on how to use the software that came with the cables.

4  Hi it is possible to add other languages to voice announcement beyond english and chinese?

5  I have bought 10 of H-777 with the base charger and standard ear pieces that comes with the product and having mic. on the ear piece problem. It will transmit the audio but the mic. won't work when pressing. We have to unplug the ear piece from the H-777 and plug back in for it to work for a little while and keep on doing so. What can I do for the ear pieces to work properly without having to keep unplugging them?

6  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?

7  Can I connect H777 with the PC whitch works on Linux platform?

8  Is an FCC license required for the H-777? Thanks.

9  Can not get H 777 software to install on system. windows 10
