Initialization
Initializing the Receiver
Before you use your GPSMAP 235 for the first time, you’ll need to “initialize the
receiver.” Initialization is the process in which the receiver collects satellite data and
establishes its (your) present position. Follow the initialization process described
below, which will usually provide a position fix in about a minute.
Before you initialize, make sure the sounder and antenna have been correctly
installed according to the instructions in Appendix A.
To turn the GPSMAP 235 Sounder on:
1. Press and hold the
P
key until the power tone sounds.
The welcome page will appear while the unit conducts a self test. Once the
internal test is complete, the mariner’s warning will appear, asking you to read and
acknowledge important information regarding the proper use of electronic charts.
To acknowledge the mariner’s warning:
1. Press the
T
key.
A flashing ‘MESSAGE PRESS PAGE’ prompt will appear at the bottom of the
screen asking you to press the
J
key.
To view a system message:
1. Press
J
.
2. Press the
J
key again to return to the previous page. The ‘select initialization’ window
will appear, with the ‘select from map’ option highlighted.
3. Press
T
to initialize the receiver from the built-in worldwide map.
A. The Welcome Page will be displayed while the
unit performs a self-test.
B. Confirm the mariner’s warning before start-
ing navigation. Remember that the electronic
chart is designed to supplement the local
government charts, not replace them.
