shows the meaning of the LED states in the expected sequence after power is applied.
Flashing means that the LED is turning on and off at a 1 Hz rate - 0.5 seconds on and 0.5 seconds off.
Debugging Guidelines:
•
If the power is on but the yellow LED doe not flash within one minute, then no satellites are
tracking. There may be excessive blockage or the unit may be defective. Make sure the unit has
an unobstructed view of the sky. Try power cycling the unit.
•
If the yellow LED does not flash within one minute and power cycling the unit does not fix the
problem, request a VERSION log to ensure that the auth code is correct.
Example of a receiver loaded with an incorrect auth code:
<ok

If the yellow LED is flashing but does not progress to solid yellow within one minute, then
insufficient satellites are tracking or the signal quality is poor and ephemeris data can’t be
received. Normally, four satellites are sufficient for a valid position as long as they are widely
