The current 85101C display/processor (8510C top box) incorporates a liquid
crystal display (LCD). An 85101C with a LCD has a serial prefix of 4116A and

Cleaning the CRT

1. Remove the softkeys cover (a plastic cover through which the front panel softkeys
protrude). Refer to figure 2.2. Carefully insert a thin, flat screwdriver blade (or your
fingernail) between the upper left-hand corner of the softkeys cover and the glass filter.
Be extremely careful not to scratch or break the glass. Pull the cover forward and off.
2. Remove the two screws that are now uncovered.
3. Remove the display bezel assembly by pulling the end that is now free. Pivot the bezel
around its left edge until it is released.
4. Clean the CRT surface and the inner glass filter surface gently, using a clean, soft cloth
and a cleaning solution recommended for optical-coated surfaces. Agilent part number
8500-2163 is one such solution. Camera lens cleaner or computer screen cleaner can
also be used.
5. Allow the surfaces to dry and then reassemble the instrument.
