41  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.
42  hi i have rt6 and i want so scan frequency when i pres scan it scans just channels how to scan frequency? thank you
Every channel represents a frequency.
43  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 firstname.lastname@example.org .
44  Trying to program RT6 with chirp and it says "Error reading data from radio: not the amount of data we want". any ideas?
RT6 has special Connect-Port design , could you please check if it is because of Poor contact ? Also RT6 use its own special programming cable , Please make sure if you use the right one ?
