Enter the code and press . The output will be turned on for a preset time (monostable mode) or
switched (bistable mode).
3.4 Changing the user code
1. Enter the code and press . The red and green LEDs will start flashing.
2. Enter the new code (from 1 to 12 digits) and press . The change of code will be confirmed by
four short and one long beep.
A secure code should contain at least 4 digits.

Starting the service mode from keypad
1. Enter the service code.
2. Press .
Starting the service mode from pins
1. Power down the code lock.
2. Put a jumper on the RESET pins.
3. Power on the code lock.
4. Remove the jumper from the RESET pins.
Starting the service mode will be confirmed by four short and one long beep. When the lock operates
in the service mode, the green and red LEDs are flashing alternately and short intermittent beeps are
generated.
