Information:
No Design Loaded
If no design is loaded:
All the LEDs on all the light bars are off.
In the Text Views screens, N/A appears as the value of guidance parameters.
The bottom line of "Design: <Name>" shows as None.
Cross-section View displays a "no design" message.Visual Status Indicators
Some system components are installed on the machine in easily accessible locations, and a look at the status indicators of the components (typically LEDs) can help you to troubleshoot problems.Lightbar System Status Indicators
As well as providing guidance information, the lightbar LEDs provide the system status information listed in Table 3.
Table 3
Lightbar System Status Information    
Problem    Cause    Solution    
All the LEDs on all the lightbars are off     There is no power to the lightbar     Check cables and connections    
The LEDs at each end of the lightbars flash repeatedly     The error estimate limit set by the GPS accuracy mode has been exceeded     Move away from obstructions and make sure that the data radio is working    
Both the ends and the center groups of LEDs flash     The lightbars have power, but are not receiving serial communications from the Display     Check cabling and that the Display is running    GPS Receiver Status Indicators
The GPS Receivers have three LEDs next to the harness connector. The behavior of these LEDs indicate the status of the receiver. These LEDs are shown in Illustration 1.

(1) Power (2) Data Link (3) SatelliteThe meaning of the receiver status LED activity is given in Table 4.
Table 4
GPS Receiver Status Led Activity    
Led    Off    Slow Flash    Flash    Fast Flash    On Solid    
Power     No power             Beta test period expired (1)     Power on    
Data link     No CMRs received or too few satellites         CMR type 0 being processed         10 Hz CMRs being processed    
Satellite     No satellites being tracked     Tracking 4 satellites or more         Tracking 3 satellites or less     Monitor mode (2)    
( 1 ) In addition to the power LED, the data link and satellite LEDs will also be flashing, and at the same rate as the power LED.
( 2 ) In addition to the satellite LED, the power LED will also be on solid, and the data link LED will be flashing.When GPS is working correctly in a single-GPS system, the power LED for the receiver will be on solid, the data link LED will flash at 1 Hz, and the satellite LED will flash slowly.When GPS is working correctly in a dual-GPS system, the LEDs on the left GPS Receiver will behave as described above in the single-GPS case. The power LED on the right GPS Receiver will be on solid, the data link LED will be on solid, and the satellite LED will flash slowly.Data Radio Status Indicators
