Mounting the Remote Head Control Knob
The Tow-Pro
®
Liberty remote head is designed to be mounted at a distance from
the main unit, allowing for a neat, convenient installation and not impeding on lower
leg airbags or driver leg room. The Tow-Pro
®
Liberty remote head is designed to be
mounted on or around the vehicle dashboard and when installed correctly, complies
with
Federal Motor Vehicle Safety Standards No. 201, which sets requirements for
devices mounted on the dashboard.
The Tow-Pro
®
Liberty remote head can be mounted directly to the dashboard, to the
centre console or through a spare knock-out switch panel and requires two holes to be
drilled as per the Mounting Guide below. For easy access in an emergency situation,
REDARC recommend installing the remote head within reach of the driver such as the
regions shaded in the diagram below.

Ensure the remote head push-button activates correctly when installed into surfaces
with a thickness greater than 0.12” / 3.0mm. Failure to activate correctly would result
in not being able to activate the override function or change modes.
Do NOT install the Remote Head in any location that may impede the activation of
vehicle air-bags.

Active Calibration
Active Calibration constantly monitors the vehicle’s direction of travel and allows the
Tow-Pro
®
Liberty to ‘learn’ and continuously confirm its mounting orientation. This
process occurs whilst the vehicle is moving and the brake is applied and will occur
with or without a trailer connected, for most vehicles.
When the unit is first powered, Active Calibration must first become confident
in the vehicle direction of travel. Until this time the LED will flash Blue/Green.

Time
During Calibration:
Once Calibrated:
When the Tow-Pro
®
Liberty is first installed it will begin learning its mounting
orientation through Active Calibration as soon as you start driving.
Until the Tow-Pro
®
Liberty has fully determined its mounting orientation the unit will
apply the brakes based on the level set on the control knob, this is indicated by the LED
glowing green with blue flashes. As the Tow-Pro
®
Liberty becomes more confident of
its direction of travel the length of the Blue flash will increase, to the point that the LED
is solid Blue which indicates it is now calibrated.
Under normal driving conditions the Tow-Pro
®
Liberty will learn its mounting orientation
within 20 brake applications. Note that the braking must be perceptible (applying the
brake while stopped will not assist calibration).
If power is disconnected (for example, if the vehicle battery is changed) calibration
memory will be lost and the unit will recalibrate itself using active calibration. This is
similar to a radio losing its clock or preset station memory.
If no trailer is connected, Active Calibration may occur as normal without any indication
from the LED, provided your brake light trigger point is active when there is no trailer
attached. The LED will already be Blue when the trailer is connected. Essentially,
whether a trailer is connected or not, just drive normally and Active Calibration will
ensure the Tow-Pro
®
Liberty learns the correct direction of travel.
