Troubleshooting guide

APPENDIX D
REPLACEMENT OF THE LCD (CONTAINER OPEN)
1. Pull out the drawer, release the interlock, and extend the locking bars to the locked position.
2. Remove the drawer head cover plate.
3. Remove the back drill plate and filler plate.
4. Remove the X-07 cover assembly (backplate).
Remove the two screws on perimeter of the cover assembly. One is on the end of cover
assembly and the other is on the side. Both screws are Phillips head screws and require a
#2 Phillips screw driver.
Lift the cover assembly out perpendicular to the lock assembly. Care must be exercised
here because the female connector on the system card mates up with an 11 pin male con-
nector on the case assembly. If removed at a severe enough angle, the 11 pin male connec-
tors may have one or more pins slightly bent. Even a slightly bent pin may prevent, or inhibit,
the reinstallation of the cover assembly.
5. With cover assembly removed, remove the straight slot/hex screw (depending on type of
screw) from center of cam. (Fig. 7 & 8) This screw attaches the drive cam to the spindle.
6. With screw removed, remove the drive cam from the spindle.
7. Remove the dial assembly and spindle by pulling on the dial knob from the front.
8. Remove the dial ring cover and the black plastic inner tube retainer by removing the Phillips
head screws.
9. At this stage, the display can now be removed and replaced by removing or loosening the
display retainer spring screw(s). In the newer versions, the ZIF connector holder is sepa-
rate from the LCD display, so that both would have to be replaced.
10. Unplug the two flex cable leads by pulling the ZIF locking levers up off the connectors.
11. Plug the two flex cable leads back into the new connector and push the locking lever back
down onto the connector. Make sure that the Five Wired set goes into the Five Slot set and
the Four Wired set goes into the Four Slot set. The flex cable leads are plugged into the
connector with the circuit lands facing down (silver side down). The display and ZIF con-
nector holder are then installed into the dial ring and retainer clip with the flex cables facing
out towards the front of the lock.
CAUTION: In the newer version of ZIF seal holder, you MUST place the screw
tab UNDER the screw tab of the outer tube retainer. Otherwise the flex
cables may be cut by the dial ring cover.
12. Replace the tube retainer, dial ring cover, cam, dial and back cover.
