Equipment Damage

Some internal components can be damaged by small

amounts of static electricity. A properly grounded antistatic wrist strap
must be worn while handling any internal component.

▲

Turn the instrument OFF, unplug the power cord, and remove the
cover.

Remove the three ribbon cables and the two-wire connector from the
front panel board.

Pop the board off of the two top mounting studs and remove the board
by lifting it up and off the slotted bottom support.

Replace the front panel board by following the previous steps in
reverse.
