4  ho acquistato coppia di rt-5rv e usa solo lingua inglese e chinese , non italiano su menu14. Come si puo' cambiare lingua ??
Mi dispiace per ora che abbiamo solo l'inglese e il cinese, ma lo faremo in futuro.
5  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 .

8  I have an RT5 and found out, that the mic does not work. Got it as a two pack a month or so ago but had never tried this radio. Is there a Mute setting that I don't know off or any other troubleshooting tips? Cheers,
Better find your seller to ask for your warranty in this situation .
