— Appears on all position screens when the Position
Dilution of Precision (PDOP) of the position fix is 10.1 or greater.
The accuracy of the fix is uncertain; do not use this fix for

Signal Quality (SQ) of a position fix falls to 3 or below. The

be overridden by the PDOP icon.

are low and should be replaced.
