IMPORTANT: The Radio Self Test needs to be performed while the vehicle is not moving.

StarFire iTC MUST be in RTK mode to perform the radio self test

NOTE: This is an average and putting the radio into it's test mode will decrease this average until it's put back into operational mode and allowed to run for several minutes.

(D) Radio Distance - Distance from master to slave radio. No ranges for this now for this handoff.

(F) Radio Temperature - Internal temperature of the radio, measured in degrees Celsius. Acceptable range of values: -40 to +75 degrees Celsius.

(G) Antenna Reflected Power - A voltage ratio used to indicate problems with the antenna. Higher values (above 75) generally indicate issues with the antenna, possibly an antenna that is broken.

(H) Transmit current - Amount of current consumed during radio transmission. Acceptable operating range is approximately 60mA or less. Value can range any where between 10 and 90 mA.

(I) Average Noise level - Level of background noise and interference seen at this radio. This is an average reading taken at regular intervals by the radio. If the radio is in setup mode (which is what happens during the radio test) will affect this reading. Average noise levels would be somewhere between 15 and 30. Levels lower than 15 are ok, but levels higher than 30 may start to shows signs of signal degradation.

(J) Average signal level - Level of received signal that this radio is seeing from the other radio transmitting to it. This value should be at least a value of 15 higher than the noise. If it is not, link between the two radios is probably not stable and reliable.

(K) Overall receive rate -Percentage of data that was successfully transmitted from master to slave radio on the first attempt. Values higher than 75 indicate a good radio link.

While the test is in progress the screen will read:

Radio Self Test in progress. . .

System is no longer in RTK mode.

Press END button to stop test.
