 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.
