2. Opening the electronic lock
6. Battery monitor, replacing the battery
Enter either the factory combination, pressing the 0 _ 1 2 3 4 5
6 buttons, or your own new master combination.
You may press the
„
C
“
key to correct the entry. In this case
you will have to repeat the entire entry sequence. Correct
entry is confirmed with a beep. The green LED will now blink
and the electronic lock is cleared for opening for a period of 12
seconds. The door to the safe can now be unlocked using the
keypad lever and the fingertip grip. The green LED will blink at
a 3
-
second interval for as long as the electronic lock is open.
The keypad lever may not be under pressure before the
acoustic and optical clearance signals are emitted. If the
keypad lever is not used within 12 seconds to open the door,
then the electronic lock will automatically be re
-
locked.
1.2 General
5. Correction with the C button
Even though operation is very simple, you should nonetheless
read these instructions carefully and completely before
starting, in order to prevent operating errors. These operating
instructions apply to an electronic lock which is installed in a
high
-
security container such as a safe. A beep will sound briefly
to verify the entry each time a button is pressed. No more than
30 seconds may elapse between entries as otherwise all the
information entered up to that point will be discarded.
3. Closing the electronic lock
Close the door and turn the keypad lever back to the stop. The
keypad lever will have to cover the red marking completely.
The electronic lock is automatically locked in this position. Two
signal tones of the same frequency will sound to indicate that
the electronic lock has been locked; the green LED will light
once.
In the interest of security, attempt to turn the handle to
ensure that the container is properly closed.
4. Time
-
out following erroneous entries
Twelve signal beeps will sound and the red LED will light if an
invalid combination is entered. You now have three more tries
to enter a valid combination. After the fourth consecutive
invalid entry, however, the time
-
out period commences; the
keypad will accept no entries during this 10
-
second period.
This time
-
out period will be extended by 10 additional seconds
following each subsequent invalid entry up to a maximum
time
-
out period of 15 minutes. The time
-
out period cannot be
interrupted 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 low battery warning period can be interrupted with the
„
C
“
button.
If the battery charge is insufficient, then a high
-
low warning beep
will sound 10 times after the combination is entered and the red
and green LEDs will blink alternately. This is to remind you to
install two new 1.5 volt (AA alkaline) batteries within the next few
days.
Replacing the batteries
: The battery compartment cover is located
to the right of the keypad housing. Slide the battery compartment
cover off the keypad housing, in the direction indicated by the
arrow
Remove the old batteries and replace them with two new 1.5 volt
AA (alkaline) batteries. The direction in which the batteries are to
be installed is shown inside the battery compartment cover. The
programmed combination will be retained during battery
replacement.
Do not use rechargable batteries.
7. Emergency opening
The electronic lock is also equipped with an emergency release
feature (double
-
bit safety lock). This special function makes it
possible to open the container even though the batteries were not
changed in due time or if the electronics failed or the combination
was lost. Furthermore, using the emergency key to unlock and open
the door prepares the system for programming a new combination;
see 8.2. The access to the emergency release lock is inside the
battery compartment; behind the batteries; see Figure 1.
Store the emergency release key carefully in a secure place. Do not
leave it in the safe!
Functioning: Insert the supplied double
-
bit key in the emergency
release lock. (The mark on the head of the key must point away from
the hinge.) Now turn the key clockwise, all the way to the stop; use
the keypad lever to release the electronic lock and open the door.
Close the door to the safe. Move the keypad lever downward (red
screw cover cap must be concealed by the keypad lever). Turn the
key counterclockwise and withdraw it from the emergency release
lock. Slide the battery compartment cover back on to the keypad
housing and affix it with the cross head screw.
