The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the right to
activate power to the trailer’s electric brakes independent
of the tow vehicle’s brakes. If the manual brake control
lever is activated while the brake is also applied, the
greater of the two inputs determines the power sent to
the trailer brakes.
The trailer and the vehicle’s brake lamps will come on
when either vehicle braking or manual trailer brakes are
applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or
sliding the manual brake control lever will display the
GAIN setting for 10 seconds and the “Trailer Brake Status
Indicator Light” will not be displayed.
