Little known modes: P-save mode, stores less music in the shock-proof memory. To toggle it on/off, hold the ``Display'' button for 2 seconds when the unit is stopped. A-play mode, automatically goes into play mode when a disc is inserted. Hold the ``Mode/Ins'' button for 2 seconds when the unit is stopped.

Note: No AGC (automatic gain control) recording. The battery life is 9.5h (PB) when "auto Power Save" mode is ON. In this mode, the memory saves only 5 sec of data. If you turn OFF this "auto Power Save" mode, the memory saves 10 sec of data (which is the ordinary amount for other portables), and the battery life gets 20% shorter (==7.6h), according to the manual.
