positioning or enter the differential mode according to the time-limited positioning (10min backward
differential) conditions. Positioning LED flashes:
a. When the remaining time is less than 2min, the positioning LED light flashes: 0.5s on, 0.5s off;
b. When the remaining time is less than 2min, the positioning LED light flashes: 0.5s on, 0.5s off;
c. Remaining time >5min, positioning LED light: 1.7s on, 0.3s off;

When the base station is in the differential state, the differential LED flashes to display the
accuracy of the base station's own positioning:
1) The base station's own positioning accuracy (error standard deviation<0.3m) includes RTK
accuracy, and the blue LED flashes: 1.7s on, 0.3s off;
2) The base station's own positioning accuracy is normal (0.3<error standard deviation<1m), the
blue LED flashes: 1.0s on, 1.0s off;
3) The positioning accuracy of the base station itself is low (error standard deviation>1m). The
blue LED flashes: on for 0.5s and off for 0.5s.

When the base station fails:
1) When there is a fault in the positioning, the DGPS (Location LED) and the Fault LED flash
synchronously: on for 0.2 seconds and off for 0.3 seconds;
2) When the differential fault occurs, the DGPS (differential LED) and the Fault LED flash
simultaneously: on for 0.2 seconds and off for 0.3 seconds;
3) When the system has a serious fault, the 5 LEDs of the function module flash synchronously
(the DGPS two-color LED flashes alternately): on for 0.2s and off for 0.3s.
