Retevis UserDB Manager
Supported radios include RT82, GPS and nonGPS. Only for use with CSV firmware types.
Press the "Download Update" button to download latest user database to your computer.
You can then press the "Flash UserDB" button to write that into your radio.
Alternatively, you can supply an RT82 formatted usercsv and browse for it. Use the "Flash from File" button to write your own provided csv instead.
For the RT82 we have added a new function which allows you to make a full flash backup of your radio.
Note: Supports updating user contacts and also making flash dump backup of radio. No installation needed, no driver install needed, and no microsoft office needed. You must unzip the files into a folder before using them. No other installation is required past this.
