Important Facts to Remember
1.
Do not mount or activate RF generating items
(cell phones, two way radios) near (less than 12")
the brake control.
2.
The P3 employs an inertial sensor. It senses
deceleration and generates an output that is based
on deceleration, thus the term "Proportional
Braking".
3.
The P3 will "HOLD" your trailer with 25% of
power setting while you are at a standstill with
brake pedal applied for longer than 5 seconds.
4.
The P3 will brake proportionally in reverse.
It will apply the appropriate brake voltage based
on deceleration.
5.
WARNING The Gross Combined Weight Rating
(GCWR) must never exceed the vehicle manufac-
turers recommendation.
6.
CAUTION Boost not intended to be used during
icy road conditions.
