2. Opening the electronic lock
The electronic lock is opened by entering the appropriate
combination (pressing seven buttons); please refer to the
examples:
Please note:
You may press the ”C“ key to correct the entry.
In this case you will have to repeat the entire entry sequence.
After a correct entry has been made the green LED blinks
once; the motor moves the bolt into its ”open“ position. The
green LED will blink once and a low-high signal sounds to
confirm that the electronic lock is in its open position. The
handle can now be used to open the door. If the system
fails to function when opening the door for the safe, then
press the handle firmly in the ”close“ direction (the locking
bolt might be jammed) and enter the combination once again.
3. Closing the electronic lock
Close the door, turn the handle back to the stop and press
any digit button.
Please note:
The motor now moves the locking bolt into its
”closed“ position. The green LED blinks once and a low-
high signal sounds to confirm that the lock is closed. The
container is now closed and locked. In the interest of security,
however, attempt to turn the handle to ensure that the
container is properly closed.
If the electronic lock was not locked correctly, then the red
LED will light and a signal tone will sound 12 times in
sequence. The LED blinking in green and a signal tone every
seven seconds indicates that the lock is ”open.“ Now repeat
the procedure as described in Section 3. Once the safe has
been locked, and in the interest of security, have the lock’s
status shown optically as described in Section 8.
4. Time-out following erroneous entries
Twelve high-pitched signal tones will sound and the red LED
will light if an invalid combination is entered. You now have
two more chances to enter a valid combination. After the
third consecutive invalid entry, however, the time-out period
commences; the keypad will accept no entries during this
12-second period. This time-out period will be extended by
12 additional seconds following each subsequent invalid
entry. The time-out period cannot be interrupted with the
”C“ button. The red LED blinks every five seconds during
the time-out period. The end of the time-out period is
indicated by the green LED blinking and a single low-high
signal.
It is now necessary to enter a valid combination twice
in order to open the electronic lock.
This is done by connecting the new battery (
9-volt alkaline
)
to the emergency contacts located at the keypad.
Important!
Observe correct polarity when making the connection
to the emergency contacts!
See Figure 1. Enter your
combination to open the safe while emergency power is
being applied.
The battery is replaced in the normal fashion with the safe
door open.
The battery is easily replaced by unscrewing the battery
compartment retaining screw and sliding out the battery
compartment (only for the 7231 keyboard; the 7233 model
has an external battery compartment) . Markings inside the

5. Correction with the ”C“ button
If you press the ”C“ button during the course of an entry
sequence, then all digits previously entered will be canceled.
Any programming mode which might have been commenced
will also be terminated. You must initiate programming once
again, from the beginning, by pressing the * button.
Exception:
Neither the time-out period following erroneous
entries nor the timed delay period can be interrupted with
the ”C“ button.
6. Charge monitoring, replacing the battery
If the battery charge is insufficient, then a high-pitched
warning tone will sound 10 times after the combination is
entered while the red and green LEDs blink alternately 10
times. This is to remind you to install a new 9-volt alkaline
battery within the next few days.
Warning:
If you ignore the low-battery warning for too long
you run the risk of having to use the emergency power supply
feature to open the lock, and thus the safe (only for the model
7233 keypad).
