6. Replace the trace rotation connector (J225, Main board), and snap the anode
lead onto the anode connector on the side of the CRT.
7. Wipe the faceplate of the CRT to remove fingerprints, then replace the bezel.
If the fit is too tight to allow the bezel to go into position, or if the CRT has a
loose fit after the bezel is completely tightened down, then the rear CRT
support must be repositioned.
To reposition the rear CRT support, loosen the two nuts that hold the support
in place. With the CRT and bezel in place, push the support towards the
front of the instrument until it is snug against the rubber manchet on the rear
of the CRT shield. Tighten the two support nuts.
1. Remove the five rear screws. See Fig. 6-4.
2. Unsolder the six bnc’s and one ground connection. (If 1700F10 Field
Upgrade is installed, unsolder leads from the battery connector.)
3. Pull the rear panel free from the chassis; be careful not to pull the
unsoldered wires.
4. To replace, reverse the procedure.
