I read this with Asian RSS R02.01.00, it shows a model number AZP03YPA20C5 GP280. I hexed to get into hambands, but there is no signalling menu and I have DTMF.

I also read in RSS ver SPA.01 (?) and it shows model 23 F2 which has a signalling screen and I setup DTMF but there is no option on the radio wide menu to enable DTMF, and it just beeps when buttons are pressed.

Any help is highly appreciated.
