Figure 12. Error condition
User-code tampering
When the user consecutively enters three wrong 5-digit user codes within 10 minutes, the
system enters a user-code tampering state. This condition is presented by the red error LED
(see
disabled. This event is logged in the EEPROM.
This condition can be exited in one of two-ways, either by waiting for 10 minutes or by
entering the administrator password to return the system back to a normal state (which
returns the LEDs back to just green Power). This event is also, logged in the EEPROM.
All the logged events can be seen in the GUI.
While the system is in the user-code tampering state, no other commands (except the
entering of the administrator password) are acknowledged by the system either through the
keys or through the GUI.

Add new user code
To add a new user code to the system, follow the steps below:
Wrong 5-digit user code
The user enters a 5-digit user code which does not match any of the valid user codes
already added in the system. This event is logged in the EEPROM and can be seen
through the GUI.
Time-out condition between 2 key presses
The gap between two key press events exceeds 5 seconds.
