Instructions

• 1). Enter the necessary starting sequence. For most ADT systems this means entering "*5" and your master code. For other systems you may have to enter your master code followed by the "8" key. Refer to your specific system's documentation for the exact starting sequence.
  
  
• 2). Enter the number you want to designate for your security code. Most ADT systems allow you to enter multiple security codes, so you must designate them with a number. Press "01" if this is the first security code you have entered.
  
  
• 3). Enter your desired security code. The alarm will beep and the new code will be programmed.
  
  
• 4). Test the new code by arming the alarm and using the new code to deactivate it.
  
  
• 5). Contact ADT if you encounter any problems at (888) ADT-ASAP.
