        Use & Maintenance
        
            - If the gyro north finder is found to have a starting current greater than 1A during use, check whether the power supply voltage meets the requirements. If the inspection is correct, the professional should be repaired.
 
            - If the gyro north finder is found to have no serial port data output during use, check whether the connection is correct, whether the serial port setting and data receiving format are correct. If the check is correct, the professional should be repaired.
 
        
     
    
        Precautions
        
            - The gyro north finder should be handled gently during the transportation process and installation process, and it is strictly forbidden to impact.
 
            - The carrier should be kept absolutely stationary during the north seeking process, otherwise it will affect the accuracy of north seeking.
 
            - The longitudinal and lateral inclination of the carrier should be no more than ±8°, otherwise it will affect the accuracy of north seeking.
