Features and Controls

Audio Warning System

Your power package is equipped with an audio warning system. The audio warning system monitors critical components and
informs the operator when a malfunction has occurred. The warning system is not capable of protecting the power package
from damage caused by a malfunction.
When an electronic control system detects a recordable malfunction, the audio warning system will sound to alert the operator.
The duration and type of horn sound depend upon the nature of the fault condition. In the case of any horn sounding, the user
should refer to the helm displays to understand the specific situation.
For the operator to view the fault code of the malfunction indicated and any recommended actions, the power package must be
equipped with a gauge package that supports the warning system and can display fault codes.
The following instruments have screens that display fault codes:
• VesselView
• SmartCraft System Tachometer
• SmartCraft System Speedometer
