My DX-396 periodically resets itself, never while I'm using it. All the
memories are gone as well as the clock settings. It usually sits on top
of a speaker in the living room, a large bookshelf speaker. Not being
able to determine a cause, I have moved it away from the speaker.
Surprisingly, it has not reset since it has been moved.

I have tried tapping the unit to simulate vibrations, giving it a good
smack or two, but no reset.

Thermal considerations haven't really changed.

Magnetic fields are the only things that would have changed. The speakers
are unusual in that they have a 6" down firing woofer that radiates into
a gap between the bottom of the main speaker housing and a sub plate that
is actually in contact with the "shelf".

I mention the point about the speakers is since the driver magnets are
probably larger than most "bookshelf" speakers would have, and the
orientation would place a larger percentage of the magnet in relation to
the top of the speaker.

This said, I don't see how magnetism would cause the radio to reset, but
I haven't seen any problems since I have moved the radio away from the
speaker.

Has anybody heard of problems with the DX-396 and spontaneous resets?

Merry Christmas to all.
