WFM 601 - Service Manual
6–23
WARNING. The CRT is a high vacuum device and must be handled with care.
Safety glasses, gloves, and protective clothing should always be worn when
handling CRTs.
4. Hold one hand in front of the CRT. Grasp the CRT just behind the anode
cap and push the CRT straight out (some pressure is needed).
1. Reposition the metal CRT shield on the CRT base mounting.
2. Remove the clear plastic cover from the back of the CRT holder. This will
make it easier to line up the connections on the CRT holder.
3. Slip the CRT part way back into position, so that the wires (and plug) from
the trace rotation coil can be fed back through the hole in the Main board.
4. Slide the CRT back into the rear CRT socket. Align the socket and CRT
base. The screws holding the rear mount down may be loosened slightly, if
necessary. The CRT should fit securely in place.
5. Press the CRT the rest of the way in by pressing straight back on the corners
of the faceplate.
6. Replace the clear rear cover on the CRT holder and screw the holder screws
back down (if they were loosened).
7. Wipe off the faceplate of the CRT to remove fingerprints.
8. Reconnect the anode connector and the trace rotation (A3J3 Main board)
plug. (To ensure the correct orientation of J3, the red lead is toward the front
of the instrument.)
9. Replace the bezel.
