 Receiver will operate normally to –40 °C. Bluetooth module and internal batteries are rated to –20 °C.

2

  The availability of the L2C code GPS signal is dependent on the US government.

 Accuracy and reliability may be subject to anomalies such as multipath, obstructions, satellite geometry, and 

atmospheric conditions. Always follow recommended practices.

4

 Depends on WAAS/EGNOS/MSAS system performance.

5

 May be affected by atmospheric conditions, signal multipath, and satellite geometry. Initialization reliability is 

continuously monitored to ensure highest quality.
