Turning On the GPSMAP 496
The rst time you turn on your new GPSMAP 496, the receiver
must collect satellite data and establish its present location. To
ensure proper initialization, the GPSMAP 496 is shipped from the
factory in AutoLocate mode, which allows the receiver to “nd
itself” anywhere in the world. Before you turn on the unit to start
initialization, be sure that the antenna is rotated up as shown on
page 1, and it has a clear and unobstructed view of the sky to receive
satellite signals.
