MD-390 Program Pre-set Buttons

I programmed the upper side button for zone toggle. It will only toggle the first 4 zones. I have 7. How can I get it to toggle through all 7.

I am talking about the upper side button (above the PTT)' not the keyboard.

Please help with your comments

Fran MD390 return button

Hi. My name is Fran , my indicative EA4FRI . I am writing to you because I see you have experience in DMR systems. I'm starting to experiment with the DMR system. I bought a DV4mini and TYT walkie MD390 . It has everything very good. It turns out that I meet a somewhat strange problem is that the return button (red button) does not answer me . I tried it with "short" press and long press and unresponsive. Do you know of any similar problem ? What can be ? I sent a video on Google Drive. Thanks for your attention.

Tytera MD-390 vs MD-380

I have been pondering or not to purchase a MD-390 or 380.  I am wanting to get into DMR but I have not made the move yet. I wanted to start off with a handheld unit and then over to a Mobile radio.  I have 2 questions mainly.

1. What advantages does the MD-390 have over the MD-380 other than being water proof?  Looks like the MD-380 will do the same things the 390 will other than has a larger battery and is water proof.  Anyone know?  Also for the price difference I was just curious.  Even at $199 for the 390 it's not a bad deal.

Also with either radio, does anyone know if there are any AA battery holders available to use with it?  I was just wondering on this?  It would be nice to have the ability to use a AA batter holder on the unit in the event of your main battery being dead. Anyone know?  I would prefer a radio that has this capability if possible.
