APPENDIX I
TEMPORARY SPLICING OF RIBBON CABLE
Missing segments on the X-07 LCD are generally caused by a cut ribbon cable. If the segments
can not be interpreted, you may be able to splice the cables well enough to get the lock open.
First you will need to remove the dial and dial ring assembly. Remove the inner and outer tubes
if possible to prevent further damage to the cables. If the cables are cut anywhere on the outside
of the container, you can spice the cables if you are careful and patient.
With the dial and dial ring assembly removed, pull
gently on the remaining end of the cut cable and lay
it flat against the container face. Now use a razor
blade, or the feeler gauge that comes with the instal-
lation package, and scrape away about 1/4” of the
insulation on the ribbon cable. See illustration.
Next lay down the other end of the ribbon cable with
the silver tip up. Now scrape away about 1/4” of the
insulation from the cut end of the cable until you see
bright, shinny copper. Reconnect the LCD, remem-
bering to use proper ESD precautions. Turn the dial
to power up the lock. Place one finger over the con-
nection and roll your finger until you get a good read-
ing on the LCD. Dial open the lock and repair or
replace.
