Caution: When the EMI box cover is removed, three printed circuit boards are
exposed. These are the CPU, the trimmer interface board, and the backplane board.
DO NOT TOUCH THE BOARDS WITHOUT USING ANTISTATIC PRECAUTIONS.
Caution: Never run the embroidery peripheral without the electronics cover in
place. The cover forms the top of the EMI shield around the boards to reduce RF
interference. Running the equipment without the shield (cover) can be a violation
of FCC regulations.
CAUTION! In removing any PCBs from the EMC 10/4, use extreme care in
handling. Portions of the boards are very sensitive to static charges and handling
them must be done using a static grounding strap as instructed in specific
procedures in this manual.
