Needle-nosed pliers are not recommended.

Procedure

1. Remove the five knobs below the CRT.

2. Insert a small, straight-blade screwdriver into the re-

cessed area on either the right or left side of the panel.

Pry gently until the panel snaps out of the front-panel

frame. See Figure C-1 for panel and recess location.
