Power supply
1.3. Things to know about the power supply
The lock is powered by a 9 V alkaline block battery (no rechargeable batteries!). If the
battery charge is insufficient, a warning tone will sound several times in succession after
the code is entered and the red LED will flash several times. Change the battery as soon
as possible. Remove the black battery compartment cover and pull the battery out of the
battery compartment. The programmed codes are retained during battery replacement.
Please always dispose of used batteries in an environmentally friendly manner.
Password
1.4. Choose password
1.4.1. Basic rules when choosing a password
1.4.1.1. Avoid the obvious passwords
•No trivial values like 000000, 000815, 123456
•Do not use your own birthday, car license plate, phone number or name (your
own, wife/husband, children, pets, company, place of residence, etc.) as
password. No standard passwords like: "safe". Writing backwards is also too
easy.
•Important passwords should be reconstructable
1.4.1.2. How to create a secure password?
•The first rule: A password is only secure if it remains secret!
•Remember passwords - don't write them down anywhere!
•Consider all keys if possible (wear marks on the keyboard betray the individual
numbers over time)
1.4.1.3. Last but not least
Consider how the password will still be retained if the owner can no longer
disclose the password (e.g., in the event of death). Leave a sealed envelope with
your notary.
