H777 VOX does not activate. I have special head sets with voice mic but two different identification numbers; X000NLQCNL and LPN RR 064286939. Should they work with each other? I tried to activate VOX by manual instructions but did not work. If I need to program, how do I obtain the software and cables?
pls log in http://www.retevis.com/programming_software to download software:
“NEW USB DRIVER” and “H-777 & H777”
Here’s the programming cable:

More details, pls check http://www.retevis.com/blog/how-to-use-vox-function-retevis-h777/
I purchased radio specifically for the VOX capabilities, however doesn’t appear that with current out of box headset is possible? What do I need? Software? if i do need software then I guess also will need the USB cable? do i need a different mic?
How do I program the walkie to scan all channels? I want my walkie to scan all channels, but the other ones to have a dedicated channel.
VOX does not work on my h777 I have activated using the software and still nothing, I recently purchased 4 of these and none of these work. Is this something I am doing wrong surely all 4 cannot be faulty? also I saw a blog that states some early “M labeled” radio do not work, can you provide 2 images to compare the ones that do to the ones that don’t please.
Thanks

“rar” is a compression file, please note you need “un-compress” it first before “setup”.
I have 3 out of ten radios that will not take the different channels i am trying to put into them. They work ok with the factory channels. Any ideas?
You mean you have trouble with programming the frequencies ?
Hi, it seems that is no difference beetwin hi power and low power about transmission. Which are the different power?
Thanks.
hello, H777 actual power is around 3W, as H7777 is not a high power radio, so it’s high power and lower is no obvious step difference. Thanks.
Thank you Elsa, very kind
My batterie on my h777 will not charge.

2. Do you have any other chargers? Try to charge.
