592 STARTING AND OPERATING
7. Use the GAIN adjustment (+/-) buttons to increase or
decrease the GAIN setting to the desired starting
point. A GAIN setting of 5 is a good starting point.
8. In a traffic-free environment, tow the trailer on a dry,
level surface at a speed of 20–25 mph (30–40 km/h) and
squeeze the manual brake control lever completely.
9. If the trailer wheels lockup (indicated by squealing
tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat Steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier
trailer, trailer wheel lockup may not be attainable even
with the maximum GAIN setting of 10.
