Procedure for Adjusting Gain
Note:Only perform this procedure in atraffic-free environment at speeds ofapproximately 20-25 mph (30-40 km/h).
The gain setting sets the trailer brakecontroller for the specific towing condition.You should change the setting as towingconditions change. Changes to towingconditions include trailer load, vehicle load,road conditions and weather.
The gain should be set to provide themaximum trailer braking assistance whilemaking sure the trailer wheels do not lockwhen using the brakes. Locked trailerwheels may lead to trailer instability.

2. Hook up the trailer and make theelectrical connections according to thetrailer manufacturer's instructions.
3. When you plug in a trailer with electricor electric-over-hydraulic brakes, amessage confirming connectionappears in the information display.
4. Use the gain adjustment (+ and -)buttons to increase or decrease thegain setting to the desired startingpoint. A gain setting of 6.0 is a goodstarting point for heavier loads.
5. In a traffic-free environment, tow thetrailer on a dry, level surface at a speedof 20-25 mph (30-40 km/h) andsqueeze the manual control levercompletely.
6. If the trailer wheels lock up, indicatedby squealing tires, reduce the gainsetting. If the trailer wheels turn freely,increase the gain setting. Repeat Steps5 and 6 until the gain setting is at apoint just below trailer wheel lock-up.If towing a heavier trailer, trailer wheellock-up may not be attainable evenwith the maximum gain setting of 10.
