Trained personnel are advised to exercise great care at all times
when working on the unit. Remember to:
◆ Remove rings, watches, or other jewelry and neckties before
you begin any procedures.
◆ Use caution near any moving part and any part that may start
unexpectedly such as fans, motors, solenoids, and so on.
◆ Always use the correct tools for the job.
◆ Always use the correct replacement parts.
◆ Keep all paperwork, including incident reports, up to date,
complete, and accurate.
Static precautions EMC incorporates state-of-the-art technology in its designs, including
the use of LSI and VLSI components. These chips are very susceptible
to damage caused by static discharge and need to be handled
accordingly.
CAUTION
Before handling printed-circuit boards or other parts containing
LSI and/or VLSI components, observe the following precautions:
◆ Store all printed-circuit boards in antistatic bags.
◆ Use a ground strap whenever you handle a printed-circuit
board.
◆ Unless specifically designed for nondisruptive replacement,
never plug or unplug printed-circuit boards with the power on.
Severe component damage may result.
