Warning System

NOTE: Alarm warnings may vary depending on your engine type. Some warnings listed
may not apply to your engine. Please consult your engines owners manual for a complete
list of engine warnings.
The System Monitor warning system incorporates the display screen, the warning horn and
the Guardian Protection system. The warning horn is located inside the remote control or is
part of the ignition key switch wiring harness.
Alarms Warnings – When a problem is detected, the warning horn sounds and the
offending icon appears on the display.
If problem can cause immediate engine damage – The horn will sound continuously
and the Engine Guardian System will respond to the problem by limiting engine power.
Immediately reduce throttle speed to idle and refer to the warning messages on the fol-
lowing pages that tell you what to do about it.

tinuously. Refer to the warning messages on the following pages that tell you what to

indications of problems. The system will respond to a problem by reducing engine pow-
er in order to maintain a safe operating condition.
NOTE: If the mode button is pressed to a different screen, the flashing alarm signal will remain
flashing to indicate there still is a problem.
