face of the CRT to insert it to the proper depth. Press the light filter against the CRT while installing the bezel. Then
hold the bezel and install the two retaining screws.
CAUTION
When reinstalling the CRT circuit board screws, ensure that the front-panel ground
lead is reinstalled on the inside front screw.
