Cold Start - Furuno GD-3300 Operator's Manual

10.5 Cold Start

10-8
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.
