Troubleshooting guide

APPENDIX E
REPLACEMENT OF THE LCD (CONTAINER CLOSED)
1. To remove the dial, cut off the knob close to the dial. (See Fig. 10)
2. Make a continuous vertical cut around the knob and parallel to the dial.
3. Pull the knob off with vise grips.
4. Loosen hub set screws.
5. Remove hub and dial. (Hub to be reinstalled later to open lock).
6. Remove the dial ring cover and the inner tube retainer by removing the Phillips head screws.
7. 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.
8. Unplug the two flex cable leads by pulling the ZIF locking levers up off the connectors.
9. 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 and the
Four Wired set goes into the Four Slot set. The flex cable leads are plugged into the con-
nector with the circuit lands facing down (silver side down). The display and ZIF connector
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.
10. Replace the hub that was removed above and tighten the set screws.
11. Execute combination and open container.
12. Remove the drawer head cover plate, back drill plate, and filler plate.
13. 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 sever 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.
14. Replace the dial and hub with new parts.
