• Determine the optimum
antenna location by obtaining
antenna reflective energy data
measurements.
• 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.
Operating on Level and Dry
Pavement
WARNING
DO NOT use the engine compression
brake or exhaust brake when operat-
ing on road surfaces with poor traction
(such as wet, icy, or snow covered
roads or gravel). Retarders can cause
the wheels to skid on a slippery sur-
face. You could lose control of the ve-
hicle and/or jackknife if the wheels be-
gin to skid, resulting in an accident.
Failure to comply may result in death,
personal injury, equipment or property
damage.
WARNING
DO NOT operate the engine compres-
sion brake or exhaust brake when driv-
ing/operating your vehicle bobtail or
with a loaded or unloaded trailer on
road surfaces with poor traction (wet,
icy, or snow covered roads) or in
heavy traffic. There may not be
enough weight on the rear axle to pro-
vide traction. Braking caused by the
normal operation of the engine com-
pression brake or exhaust brake could
cause you to lose control of the vehi-
cle, resulting in an accident. Make
sure the engine compression brake or
exhaust brake is switched "OFF" when
driving bobtail or with an unloaded
trailer. Failure to comply may result in
death, personal injury, equipment, or
property damage.

To reduce vehicle speed, put the engine
brake or exhaust brake ON/OFF switch in
the "ON" position. Remove your foot from
the accelerator pedal and clutch pedal. The
engine brake or exhaust brake will
immediately begin to operate, slowing the
vehicle.
For operation on dry and relatively flat
surfaces, when greater braking power is
not required, put the two-position selector
switch in the "LOW" position.
For operation on dry pavement when
maximum braking power is required, put
