Initializing the Receiver
The first time you power up your new GPSMAP 172/172C, the receiver must be given an oppor-
tunity to collect satellite data and establish its present position. To ensure proper initialization, the
GPSMAP 172/172C is shipped from the factory in AutoLocate mode, which allows the receiver to "find
itself" anywhere in the world. To speed up the initialization process, we recommend using the graphic
initialization process described on the next page, which usually provides a position fix within a few
minutes.
Before you initialize, make sure the GPSMAP 172/172C unit and antenna have been correctly
installed on your vessel according to the instructions in Appendix G. The antenna needs to be in a
location with a clear and unobstructed view of the sky to receive satellite signals.
To turn the GPSMAP 172/172C on:
1. Press and hold the POWER key until the power tone sounds and the display comes on, then release
the POWER key.
An introduction page appears, asking you to read and acknowledge important information regard-
ing the proper use of the unit.
To acknowledge the introduction:
1. After reading the introduction page, press the ENTER key if you agree.
