LED Indicators
There are 3 LED indicators on the KML 5000: Yellow, Green, and Red.
When the KML is powered on from a “cold boot” state, the yellow indicator will flash in
5 second intervals (5 on, 5 off). When a GPS signal “lock” is acquired the yellow LED
will cease activity and the green LED will flash briefly every 32 seconds.
Although this seems like long intervals, this sequence indicates normal operation.
Below in figure 3-3 is a table showing operational and error LED activity.

* This will occur when the vehicle is started and will continue until a satellite signal is found. At
this point the yellow LED will cease activity until the vehicle is turned off.
** When the vehicle is turned off, the KML writes the date, time and location to the internal flash
memory. This is displayed as a quick flash of both yellow and green LEDS after which LED
activity will cease until the vehicle is started.
*** This occurs when the media card is inserted. All LED's will flash rapidly until GPS data is
successfully written to the media card at which point the red/green LED will blink green. If an
error has occurred, then the red/green LED will be a solid red.
