Wiring:

The cigarette plug model plugs it into your cigarette lighter and requires no further
wiring.

If you have a lightbar that has an 11-conductor cable, refer to the chart below for
important wiring information.

NOTE: For internal fuse replacement see information on next page.

WARNING! All customer supplied wires that connect to the positive terminal of
the battery must be sized to supply at least 125% of the maximum operating
current and FUSED at the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!

Scan-Lock™:

To cycle forward through all patterns: Apply power to the control wire of the
function you want to change, then apply power to the BLK/YEL (Scan-Lock™) wire
for less than 1 second and release. This will change the pattern. Repeat for next
pattern.

To choose a pattern: While cycling through the patterns, when you find the pattern
you want let it run for more than 5 seconds and it will lock in and become the default
pattern.

To reset to the factory default pattern: Turn off power. While applying power to the
Scan-Lock™ wire, turn power on to the light(s) you want to reset.

Scan-Lock can be connected to a customer supplied SPST switch.

Hi/Low Control:

Option 1: Latching Mode: By applying +voltage to the VIOLET wire for less than 1
sec., the power supply is “latched” into Low power operation. The unit must be turned
off and then back on to restore normal, Hi power operation. A momentary switch is
best for this method.

Option 2: Level Mode: Applying +voltage to the VIOLET wire for more than 1 sec.
holds the power supply in Low power mode until that voltage is removed. A toggle
switch is best for this method.
