LED Indicator Description
The device status is clearly indicated by three multi-color LEDs:
| Indicator | Color | Status | Meaning | 
|---|---|---|---|
| PPS | Red | Off | No RTCM differential data is being received from the CORS server. | 
| Flashing | RTCM data transmission is normal. | ||
| RTK | Blue | Off | RTK positioning is not fixed (standard precision). | 
| Steady On | RTK positioning is fixed (centimeter-level precision). | ||
| LTE | Green | Off | 4G network access has failed. | 
| Steady On | 4G network access is successful. | 
Important Note:Â For reliable operation, please use a stable 5V/2A power supply and adhere strictly to the hardware connection guidelines provided in the User Manual.
