  • Page 5: Warnings And Cautions

    Warnings and Cautions Caution: Use this radar at your own risk. This radar was designed for use as a navigation aid. It should not be used for purposes that require precise measurements of direction, distance, topography or location. Always compare the navigation information received from your radar with data from other navigation aids and sources.
  • Page 6 WARNING: Microwave Radiation Hazard The microwave energy radiated by a radar antenna is harmful to humans, especially to the eyes. NEVER look directly into an open waveguide or into the path of ra- diation from an enclosed antenna. Radar and other ra- dio frequency radiation can upset cardiac pacemakers.
