the Caution Flashing Mode
To step through the different caution modes, initiate
caution-mode by connecting the two caution-mode
together (typically done with an ON/OFF toggle switch).
Once caution mode is initiated, press and release the TIME-SET
button to advance to the next caution mode.
The modes will change in this sequence:
Caution Mode #1> Flashing Red
Caution Mode #2> Flashing Yellow
Caution Mode #3> Alternating RED / YELLOW (SYNC 5 board only)
Caution Mode #4> Flashing Red, Walk and Don't Walk lights alternate
(like a train crossing Wig Wag) (SYNC 5 board only)
When in caution-mode #4, pressing the TIME-SET button will flip back
over to CAUTION MODE #1
Note: The caution mode setting will be retained even if power is
