Mine showing DT-Dynamic / 2013.01.15
(Brand new unit)
Operating OK - except for the center button (timing).
Manual says 2-3 seconds hold to turn off. Mine (under this FW) is actually more like 1 second. Makes it almost impossible to go back one folder - have lost count of the number of times trying to do this, and accidentally switching the unit off.
Very frustrating. Love the sound. But a 5 year old could have designed a more functional UI. Frustrated!
How long on the center button for the 20111223 DT firmware (switch-off)? If it's better, I'll use the older FW.
