The Handset Introduction
POWER LED (GREEN): The Power LED indicates that the
system is powered up.
ALARM LED (RED): The Alarm LED will illuminate when the
system detects a fault. An error code will also be displayed
in the LCD and in the error log.

CONNECTION LED (AMBER): The Connection LED will flash
when a call is ringing at the receiving end and will
illuminate steady when a connection is made.
SYNCHRONIZATION LED (GREEN): This is a dual function
LED. Initially, the LED will illuminate when the system has
synchronization with a satellite. When the system has
established a data call, the LED assumes its secondary
function as a data transfer light. When data is being
transferred (sent or received), the LED will light. This is a
quick visual reference during data communications.
