ENGINE OPERATION - Operating Instructions EMI susceptibility has been designed with a high tolerance against EMI and in most normal circumstances, if not all, electromagnetic energy-emitting devices that meet the Federal Communications Commission legal requirements should cause no interference. Ensure that the optimum antenna type and mounting arrangement is being used. Ensure the accessory equipment is properly constructed for maximum filtering to reject incoming electromagnetic noise.
1 WARNING Do not operate the engine compres- sion brake when driving/operating your vehicle bobtail or with a loaded or un- loaded trailer on road surfaces with poor traction (wet, icy, or snow cov- ered roads) or in heavy traffic. There may not be enough weight on the rear axle to provide traction. Braking caused by the normal operation of the engine compression brake could cause you to lose control of the vehi- cle, resulting in an injury accident. Make sure the engine brake is switch- ed "OFF" when bobtailing or with an unloaded trailer. Failure to comply may result in death, personal injury, equip- ment or property damage.
System EMI Radiation Levels Electronic components are required to pass various PACCAR and industry EMI specifications. Our testing has shown that when the engine is properly installed and maintained, it will not interfere with properly installed onboard communication equipment. If any interference condition is noticed, follow these suggestions to reduce the amount of EMI: 1. Locate the accessory receiving antenna further away. 2. Check with the accessory supplier representative in your area to: Accurately calibrate the accessory for proper frequency, power output, and sensitivity. Determine the optimum antenna location by obtaining antenna reflective energy data measurements.
Operating on Level and Dry Pavement Tips for driving on level and dry roads. WARNING Do not use the engine brake when op- erating on road surfaces with poor traction (such as wet, icy, or snow cov- ered roads or gravel). Retarders can cause the wheels to skid on a slippery surface. You could lose control of the vehicle and/or jackknife if the wheels begin to skid, resulting in an accident. Failure to comply may result in death, personal injury, equipment or property damage. Remove Foot from Accelerator Y53-1166-1G1 (08/2018) 23 30 40 50 20 60 10 70 0 MPH 80
