- By holding button 1,2,3 or 4 for 2sec, the power LED goes out.That means you have successfully changed the volume, where 1 is the minimum volume and 4 is the maximum volume.
- Selecting a folder is now possible via software. If you keep key 16 pressed for 5 seconds, the power LED goes out. You are now in programming mode. By pressing a key from 1 to 16, you select the corresponding folder.
