Furuno GP-3300, GD-3300 manual Cold Start, 10-8

10.5 Cold Start

Cold start is automatically executed at initial power application or when the GPS memory is cleared. This is done to acquire the Alma- nac to receive a GPS satellite. You can also do the cold start manually when the Almanac is too old to acquire a satellite; for example, when the unit has not been used for about six months. Manually cold start- ing the GPS receiver erases the existing Almanac to receive the cur- rent one.
