21  It's said that the RT-5R has the option of being charger with a USB directly into the phone (no charging station). Is this also the case for the RT-5? Me and a friend are planning on buying a pair, with only a USB-charger available for charging (mounted on a motorcycle).
RT5 and RT-5R do no use USB charger , we only have RT24 has USB charging cable and especially for Euro-Market . Please check here -- http://www.retevis.com/rt24-pmr446-license-free-walkie-talkies
22  Hi, I have a RT-9000D 66-88Mhz purchased tho weeks ago. At the radio I can setup channels with 6.25kc space, i.e. 72.60625. But the configuration software will only accept channels with 12.5kc space. So if I read the setup from the radio the software will truncate to 12.5kc space. The software is downloaded from this web site. Cheers!
Hello, "At the radio I can setup channels with 6.25kc space, i.e. 72.60625.", from here, you should mean step, not channel spacing. In RT-9000D software, the step has: 2.5, 5, 6.25, 10, 12.5, 20 etc.. It alreay have 6.25, same as setup from the radio, so it should be no problem,dear? greetings!
23  I cant activate the vox function on my h777. i activate the vox via software, and try different values (1-5) withouth sucess. please how activate it?
I'm really sorry to tell that H777 don't have the VOX function . We'll change the ads as soon as possible .
24  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.
25  What settings have to be done for the best signal?
1.Full charge your battery .
2.Check your antenna .
3.Set the suited squelch level according to your communication surroundings.
4. If you want to extend the communication range ,you could make it work with repeater .

27  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.
28  How do you change the radio language. 5 of the radios speak English, the last in Chinese. We are getting noise on the radios when travelling on an electric golf cart. Is there any noise cancelling function available? Is there a way to lock in the frequency so it could not be accidentally changed? The programming software does not have an exe file for the Retevis RT5 brand
1. Chnage the language : Push MENU - channel 14 ,then you will see the VOICE and choose ENG will be ok .
2.Press # key for two seconds then the keyboard will be locked . Same way to unlock .
3.About Cancelling the noise ,please press MENU- channel 0, change the SQL's level .
