Quick Turn Off All the Preset CTCSS/DCS Tones on Retevis RT76P

Quick Turn Off All the Preset CTCSS/DCS Tones on Retevis RT76P

Last month, we did a firmware update on Retevis RT76P, a very important idea is that you can quick turn off all the preset CTCSS/DCS tones.  

As we all known, if two radios have the same CTCSS/DCS tones, and the tones can keep their privacy when they communicate, avoid unnecessary distractions. But some customers think it is not a good operation if we preset the CTCSS/DCS. So we do a good update for this. 

Before to turn off all the preset CTCSS/DCS tones, you need to do a firmware update firstly. 

You can download the latest firmware on RT76P support page: https://www.retevis.com/retevis-rt76p-gmrs-radio-portable-walkie-talkies/

and follow the update insturction: https://www.ailunce.com/blog/how-to-upgrade-retevis-rt76p-firmware 

Press the "PTT+9" together, then turn on the radio, when hearing " off", the preset CTCSS tones are canceled.
