The “Page / Status” LED on the PA-IP can be programmed to one of three different modes. Factory Setting: Paging Mode OFF Mode: In this mode the LED will not light during normal operation. It will only light (blink) if it cannot register with the programmed SIP server or while manually resetting all network parameters to factory default. On Mode: The LED will remain ON when the unit is powered and registered. The LED will flash if registration is lost and alarm is active. Paging Mode: The LED will remain OFF in the idle state, light steady when the page is active, then turn OFF when the call is completed. The LED will also light steady during Multicast paging.
