Battery
If there is insufficient battery voltage, the display shows the
"
Battery flat
" message
.
If you observe the warning just mentioned, the battery for the lock must be replaced as
quickly as possible (section 3.6.).
The lock can be operated until the battery voltage drops below 6.5 volts.
No codes or settings are deleted when a battery is replaced. You only need to check the
date and time, and reset them if necessary (section 3.5.).
NOTE:
Do not use rechargeable AA batteries (accumulator batteries) because they do not
have enough capacity to ensure fault-free operation!

Tamper block
After 5 invalid code inputs, the keypad is blocked for 6 minutes. The remaining lockout
time is shown on the display, and it cannot be bypassed. If the incorrect code is entered
again after the lockout time has elapsed, the lockout time of 6 minutes will start again.
From the tenth successive incorrect input onwards, the lock will block inputs for 20
minutes. The lockout time ends as soon as the valid code has been entered correctly.
