Avoidance zones
A beeper alerts you as the machine approaches an avoidance zone.Avoidance zones are designated areas that you must keep away from. Avoidance zones can be sitewide, or avoidance zones can be specific to a particular design surface. The AccuGrade System provides avoidance zone proximity detection at the bucket tips and at the receivers.Site avoidance zones
When the system is turned on, Site avoidance zones are automatically loaded from the AccuGrade System data card and displayed in the Plan View. Site avoidance zone proximity detection is provided until the Display is turned off. Note: If the Site avoidance zone cannot be loaded, the Display will be turned off. The data card with the avoidance zone must be removed from the Display in order to continue operation. Contact your site supervisor immediately.Design avoidance zones
Design avoidance zones are specific to a design surface. Design avoidance zones load from the AccuGrade System data card as the design is loaded.Design avoidance zones are shown in the Plan View of the Display. Design avoidance zone proximity detection is provided while the design surface remains loaded.Note: If the Design avoidance zone cannot be loaded, the selected design will not be loaded. Select an alternative design surface in order to continue. Contact your site supervisor immediately.No avoidance zone guidance
While any of the following warning messages are displayed, avoidance zone guidance is not given:
"V. Low Accuracy"
"No GPS Data (Left)"
"No GPS Data (Right)"

Your supervisor can configure the display in order for you to set the warning distance. This distance can vary with the selected machine type. Ask what the avoidance zone is set to for your machine.First Level Avoidance Zone
If you are within three times the warning distance, the following warnings are activated:
The avoidance zone (1) becomes filled with a magenta color.
If configured, the "Avoid. Dist." (2) text item shows the distance and direction to the closest avoidance zone design boundary.Refer to Illustration 1.
