2  Can you sent me a manual for the RT7? I have the programming cable and software but how do i make one handheld switching with VOX? just a V at Vox and sent it to the set is not enough. Thanks.
3  We had one of our ten radios get the language switched over to chinese I think. While it is not a huge issue it is frustrating since we can't change channels easily. How do we change this?
The language could be changed by -- under the 10 channel ,push PTT and Moni together ,then switch on the radio to change ,here is the manual -- http://www.retevis.com/resources_center/mannual/H-777_H777_RT6S_R888splus_NEW.pdf .
Issues of Channels please contact your seller to help ,it maybe need to change the knobs .Thx.
4  Most of my contacts told me thatmy RT3 is very, very quiet compared with other radios from Hytera or Motorola. Is there any chance to improve certain values, that my voice will be MUCH louder on the other side. I bought a Kenwood mic, the improvement is notable but even still the half of the radios mentioned above. Thank you
Is it still quiet when you make it talk to the same model as RT3 ? Please reply mails to email@example.com .
5  Which software do I use to program the RT23? Nothing on the CD that was sent has RT23. Only RT3,5,8 or 9000.

6  Are the RT5 handheld transceiver "license free"
Not really . But RT24 is totally license-free , here is the link : http://www.retevis.com/rt24-0-5w-2w-uhf-pmr446-license-free-radio/
7  How can I set the power to low in the repeater mode
For better communication , we only set high power when in the repeater mode , may I ask why you want to set it to low power ? Do you use it this way frequently ? If so ,we could consider to add it on later production .

If so , you could try to program by CHIRP -- http://chirp.danplanet.com/projects/chirp/wiki/Home

About 2-3Km usually .
10  Dear Friend I am happy with the product I've bought RT7 and H777), but I am not able to change the program inside (for instance, I would like to use RT7 and H777 together). I have an IMac and I need to know how to do it. Best regards Franco
