dtr620 have two computers that can not communicate, it is to be different band
Hello and welcome!
I don’t have any firmware for the DTR620 specifically. I have no idea if the DTR650 firmware would work with the 620.
If they’re like the 650, there are no different “bands”, just channels.
Have you tried a factory reset?
- Turn the radio on
- Hold the Home key and press the PTT button three times
- Release all keys
- Press the Down, Up and Right Soft keys sequentially
- Hold the Home key and press the PTT button three times again.
- You should see the radio restart
Congratulations Andy by topic
I’m coming in forum
I’ll try something
