Subj: DSK Power Supply                                       June 29, 1994


Dear C5X DSK Users:

A potential shorting condition exists on the c5x DSK, If the regulators are
bent, allowing them to touch, a short condition exists. We suggest you check
the two regulators before you plug in your power supply. As a precaution, we
also recommand you bend them away from each other before you start using your
DSK.
