Question: How do I find and change the security code?
Answer: The security code is under the cover.
To change your remote access code:
After the two-beep signal press 99. The system beeps once.
Enter your new Remote Access Code (any number between 100 and 999, except for 323, or 523). The system beeps twice. Note: A power failure might cause the Remote Access Code to return to its original setting.
