Initializing the Receiver
The first time you turn on the GPSMAP 188/188C Sounder, the
receiver must be given an opportunity to collect satellite data
and establish its present location. To ensure proper initialization,
the GPSMAP 188/188C Sounder is shipped from the factory in
AutoLocate Mode.
Before you initialize, make sure the GPSMAP 188/188C Sounder
unit and antenna are correctly installed on your vessel according to
the instructions in the Appendix. Install the antenna in a location
with a clear and unobstructed view of the sky.
