Initializing the Receiver
Getting Started
The GPS 152’s keypad system is designed to allow for fast, convenient selection of navigation
options and data entry. The Getting Started Tour will introduce you to the keypad and provide a
“hands-on” lesson in using the GPS 152.
The GPS 152 Quick Reference Guide contains helpful tips on using the unit and performing
various navigation tasks. It’s a good idea to keep the Quick Reference Guide nearby whenever you’re
operating your new GPS 152.
Initializing the Receiver
The fi rst time you power up your new GPS 152, the receiver must be given an opportunity to
collect satellite data and establish its present position. To ensure proper initialization, the GPS 152 is
shipped from the factory in ‘AutoLocate’ mode, which will allow the receiver to “fi nd itself” anywhere
in the world. To speed up the initialization process, we recommend using the graphic initialization
process described on the next page, which will usually provide a position fi x within a few minutes.
Before you initialize, make sure the GPS 152 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 GPS 152 on:
1. Press and hold the POWER key until the power tone sounds and the display comes on, then
release the POWER key.
The Welcome page will appear while the unit conducts a self-test. Once the internal test is
complete, a Warning page will appear, asking you to read and acknowledge important information
regarding the proper use of the unit.
To acknowledge the warning:
1. After reading the warning, press the ENTER/MARK key to agree and move to the next display.
