Malfunctions
Battery
If there is insufficient battery voltage, a warning signal will sound several times in
succession after you enter the code, and the red LED will also flash intermittently.
If you observe the warnings just mentioned, the 9 V block battery for the lock must be
replaced as quickly as possible (section 3.4.).
Tamper block
After 4 invalid code inputs in succession, the keypad is blocked for 1 minute. During this
lockout time, the red LED lights up once every 10 seconds, and no code can be entered.
If two more incorrect codes are entered again after the lockout time has elapsed, the
lockout time of 1 minutes will start again. The lockout time ends as soon as the valid code
has been entered correctly.
Basic rules for secure codes
What you should avoid:
•
Don't use commonplace sequences such as 0000 or 1234.
•
Don't use your own birthday, or any car registration numbers or phone numbers.
•
Don't use a code that you already use elsewhere.
How should a code be structured?
•
The code should not have a logical structure.
•
Use all the keys, as far as possible (the keypad shows signs of wear over time,
revealing the individual numbers used in the code).
Keeping a code secure:
•
A code is only secure if it stays secret!
•
You should memorise codes
–
don't write them down.
•
Think how the code would still be kept available in case the person who has it is no
longer able to disclose it (e.g. if they die). Deposit a sealed envelope with your notary.
NOTE:
If the code has been forgotten or can no longer be reconstructed, the safe interior
must be drilled open and repaired or replaced at the owner's expense!
