1Wait a few seconds after powering up the carriers, then verify that the red OUT OF SYNC LEDs on all carriers are lit. This is normal when no radio modules have yet been installed. The CONTROL/EXPANSION LEDs (Model 117A4 only) should also be lit and blinking:

~Model 117A4 control carrier = Green blinking

~Model 117A4 expansion carrier(s) = Green blinking

A Model 117A3 carrier has no CONTROL/EXPANSION LED, but the DIP switch in Slot 4 of the carrier must be set correctly to either Control or Expansion.

The following illustration shows the correct LED status for a four-carrier installation with no radio modules installed yet. This example installation has three 117A4 carriers—one acting as the control carrier and the other two acting as expansion carriers—and one 117A3 carrier acting as an expansion carrier.
