[PCR-1000] EPROM Corruption

Sun, 1 Sep 2002 16:21:04 -0400

I had noticed quite a while ago that my PCR1K was more than warm to touch in
the rear of the unit.  I found this a bit strange for a radio with an
external powersupply and without a transmitter.

I added taller rubber feet (1") under the radio.  It usually rests on top of
an external Zip drive that itself is a very cool device.  The taller feet
seemed to have created more vent space and solved the problem -- radio is
slightly warm to the touch but noticeably cooler than before.

Thanks.
