What does the 'NOT READY' message mean on my keypad display?

The 'NOT READY' message appears when one or more burglary protection zones are open or faulted. This means the system is not ready for arming. Press the [∗] READY key to display which zones are open, then close or bypass those zones. Once all zones are closed or bypassed, the READY indicator light will come on. (Page 10)
