Transmitter Troubleshooting
!
WARNING
When testing the transmitter, the receiver can become active and cause system operation. Always
assume the system is working and will respond when testing a transmitter.
7.3.1
Normal Operation
When the transmitter is operating normally, the LED indicator emits short flashes at a low rate when no
commands are activated, and at a higher rate when a command is activated.
Some transmitters use a red LED only. Others use a multicolored LED that flashes green when no problems
are present and turns red when other problems are encountered. The LED also turns AMBER to indicate a
hard-wired pendant cable connection on those transmitters equipped with it.
