3. Remove the old glass LCD display from the bezel.

Note

Make sure the new LCD display is clean (free of lint and fingerprints)

before placing it in position in the bezel.

4. Position the new glass LCD display in the bezel; the silver face should face the rear,

and the stepped portion of the glass should be directly under the elastomeric slot on

the bezel.

5. Drop the elastomeric strip into its slot on the bezel.

6. Position the translucent light-dispersing back panel over the silver side of the glass

LCD display. Make sure the guide pins on the light dispersing back panel are facing

up and that they are on the side opposite the elastomeric strip.

7. While holding the LCD assembly (face down) in one hand, position the PCA (fuse

side up) over the bezel; match the guide holes in the PCA with the plastic guide pins

on the bezel and the translucent light dispersing back panel. After the LCD assembly

is in position, lock it in place by pressing (below the display) the bezel against the

PCA; listen for the tab on the bezel to snap (lock) into position on the PCA.

8. Secure the PCA to the LCD assembly by installing the two screws that attach the

PCA to the bezel. These screws also ensure contact between the glass LCD display,

the elastomeric strip, and the PCA.

Reassembling the Tester

To reassemble the Tester, logically reverse the previous disassembly procedures. In the

process, make sure to re-establish all electrical connections; specifically, the elastomeric

strip for the LCD, the red and black plastic shields for the input terminals, and the two

spring contacts for the Insulation Test Probe. Also make sure all parts are correctly

aligned and positioned; do not force-fit any of the parts into position.
