4.9.15 PIN Code Length/Factory Default Settings
You must be very careful before using this command!
Changing the PIN code length also erases the entire memory
contents, including all user and special codes, and return all
codes to their factory default settings.
To change the PIN code length:
1. Enter Programming mode.
2. Select the desired PIN code length as follows:
00 – Returns to factory defaults and sets a 4-digit code.
05 – Returns to factory defaults and sets a 5-digit code.
06 – Returns to factory defaults and sets a 6-digit code.
08 – Returns to factory defaults and sets a 4- to 8-digit code
Both LEDs flash red.
3. Enter your 4-digit Programming code
If the Programming code is valid, all memory is erased. You
hear three beeps and the controller returns to Normal mode.
If the Programming code is invalid, you hear a long beep and
the controller returns to Normal mode without erasing the
memory contents.
