1
Wait a few seconds after powering the carriers, then verify that the carriers’ OUT 
OF SYNC LEDs are not lit.
2
At this stage of your installation, the LEDs displayed should again match the first 
or fourth lines of the SYNC and CONTROL/EXP LED Codes label, depending 
on whether the carrier is the control or an expansion carrier. (Keep in mind that a 
Model 117A3 carrier does not have a CONTROL/EXPANSION LED.)
