Motorola GPS Products M12 Oncore User’s Guide Supplement Revision 1.0 01/25/00 POSITION LOCK PARAMETERS This message allows the user to enter a threshold speed (default 0.5 m/sec) and a threshold distance (default 100 meters). The position will be locked if the current speed and distance traveled are both less than their respective thresholds. The parameters will be remembered through power cycles if battery back-up is provided. Default values: Speed threshold = 0.5 m/s Distance threshold = 100 m 32
