INTRODUCTION
The X-08/CEX-08 uses sophisticated computer security and makes dialing much easier
than that of traditional combination locks. The microprocessor in the lock recognizes a
number as part of a combination when you stop dialing on that number and wait for the
number to be registered. This enters the number into the computer’s memory.
Your X-08/CEX-08 lock has been shipped preset in the Single Combination Mode with
the factory combination of 50-25-50.
If you have a CEX-08 lock, be sure to read the section on “CEX-08 Features”.
LOCK ON BACK COVER
The Lock On Back Cover (LOBC) feature provides a locking mechanism that locks the
back cover in place after installation. The design is such that the back cover cannot be
removed without visible damage unless the combination is known, regardless of whether
the lock is locked or unlocked.
Note: Because of the LOBC feature, you cannot remove the cover to read
the lock serial number after the lock is installed. Since you may need the
serial number of the lock to reset it if the combination is lost or forgotten, it
is important that you keep a record of the lock serial number in a secure
place.
To Remove the Lock on Back Cover:
1. Unlock the lock and retract the bolt in order to gain access to the back cover.
2. Release the container locking bolts.
3. Locate the unlocking button on the back cover.
4. Turn the dial to the left to extend the bolt.
5. Dial the combination(s) to open the lock. OP will appear.
6. Before turning the dial to the right to retract the bolt, pull out on the unlocking
button.
7. While holding the button out, turn the dial slowly to retract the bolt to the unlocked
position.
Caution: Removal of the back cover with the lock bolt extended will cause a
Covert Entry condition on the CEX-08. This condition requires that the Covert
Entry (CE) indicator be reset. See the section on CEX-08 Features.
8. Remove the back cover screws.
9. Remove the back cover assembly.
