2. WARNING gt After a power up from cold the NAVIGAT X MK 2 requires a settling time of three hours before reliable heading data is available Power up the system at least three hours before leaving harbour Power down the system during long docking periods only Make sure that the NAVIGAT X MK 2 has settled before using its heading as the reference for heading control systems RADAR ECDIS etc A magnetic heading source should be made active only in case of failure of the gyrocompass es WARNING gt Before using this system operators must appropriately trained and familiar with the operating procedures and safety instructions contained in this manual Keep system manuals in a well known readily available location CAUTION The supporting fluid in the gyrosphere container will start freezing at temperatures below 0 C The NAVIGAT X MK 2 may no longer be operated when the ambient tem perature at the gyrocompass location falls below 10 C while the com pass is in operation or when the ambient temperature falls below 0 C while the compass is not in operation CAUTION Any service work on the gyrosphere is to be carried out by authorized N service personnel only CAUTION AN Do not clean the compass housing with organic solvents acetone or any other substance which could damage or discolour plastic Use only soapy water or a mild detergent to clean the compass ho
