嗯, 下次“螢幕慢慢消失” 可以做 MASTER RESET 如下(手指頭可不要打結,不太好按耶)
1. Power the unit OFF
2. Hold down the two Soft Keys for 2 seconds
3. While continuing to hold the 2 Soft Keys down, press and hold down the Power button for an additional 5 seconds
4. Release all buttons, and select YES to the prompt asking "if you want to clear all user data?"
