1.3 TEST FUNCTION

Diagnostic software is built into the system. To activate it, press

the ENTER/TEST button until all of the display digits fill with a

checkerboard pattern, and then release it. This display will flash on

and off three (3) times. Next, all digits will be filled with a second

checkerboard pattern, the inverse of the first, which will also flash

on and off three (3) times. Careful monitoring of these patterns will

verify operation of every element of the display unit.

If the test is successful, the word “GOOD” will appear in the

display window for three seconds. (If the test is not successful, the

word “BAD” and an error message identifying the error will be

displayed. In such case, the unit will cease to function and must be

considered unserviceable until corrective action is taken.) This is

followed by:

1) The K-factor setting (Pulses Per Gallon) and units of measure

the system is set to (gallons, liters, pounds or kilograms).

2) LT ( ): Loran or GPS Type (without signal, will display ‘LOF’)

3) The distance to waypoint or destination as shown on the Loran-

C or GPS receiver to check the data interface integrity. (not

available without signal)

4) Maximum usable fuel setting.

5) Software version.

6) If the system is not capable of reading the navigation receiver

data, the word “LBD” will appear in the display window.

NOTE: a) Using the test function while the engine is running will

cause the computer to lose 17 seconds of fuel count.
