Repair and Replacement Procedures
Removing and Replacing the Front Panel Group Assemblies
d. To install a new RPG, reverse the above steps. A new cable, nut, and
washer are included with the new RPG. When reinstalling the RPG
cable, W12, bend the cable toward the right side on top of the
display to front panel interface board cable.
4. Reinstall the hole plugs in the front case. Apply one drop of isopropyl
alcohol on each hole plug to lubricate it, making it easier to install. Use
alcohol only in a well ventilated area. View the hole plugs from the front to
ensure that they are fully seated. These hole plugs must be installed to
maintain water-tight integrity.
5. Reinstall the RPG knob. Refer to step 3.b of this procedure.
6. Perform the steps under “Final Assembly Procedure” on page 164.
