By pressing different buttons of your unit you can enter the different modes. Exit test mode by pressing stop/power off. Step back from any modes by pressing the stop button! When I say ``change with...'' above, I mean that you can step through the chosen mode.

Attention! Don't press any buttons if you don't know exactly what you are doing. The service manual contains all the details of how to handle the different modes.

Entering Test mode on the MS200

This is the same method used for the MS100.

Some modes I've tried

Maybe someone with the service manual could fill us in on the functions of the other sub-modes, etc.?

It is rather educational to put the unit into "test mode" (turn the unit off, then hold the enter/sync button and display button and press play) and play back an MD in "Normal" mode (press Bass/Del, then >> until the display says "Normal", then press "play").

When you play an MD in this mode, the level-meter at the top shows how full the unit's anti-shock buffer is. You can stop the MD and toggle P-Save mode by holding "Display" for 2 seconds (MD has to be stopped). When P-Save mode is off the buffer fills up and stays full, when it is on "auto" the buffer fills up, then depletes for a while, then fills up again, and so on. You can watch the indicator bounce around. If you jostle the unit a lot at this time the indicator will go down but I didn't manage to make it skip. Maybe I wasn't violent enough.

Press "stop" to back out of any test modes you don't want to play with anymore and again to turn off test mode.
