Initializing the Receiver
The receiver is shipped from the factory in
AutoLocate™ mode, which enables the GPS 125
Sounder to determine its location anywhere in the
world. To speed up the initialization process, we recom-
mend using EZinit described below, which will usually
provide a fix in a few minutes.
Before you initialize, make sure your GPS 125
Sounder unit, antenna, and transducer have been cor-
rectly installed on your boat according to the instruc-
tions in Appendix A.
To turn the GPS 125 Sounder on:
1. Press and hold
P
until the receiver turns on.
The welcome page will be displayed while the unit
conducts a self test.
Once testing is complete, the welcome page will be
replaced by the status page, with the EZinit prompt
ready for you to select one of two initialization
methods:
•Select Country––allows you to initialize the
receiver by selecting your present position from a
list of countries in the GPS 125 Sounder’s internal
database. This usually provides a position fix in a
few minutes.
•AutoLocate
TM
––allows the GPS 125 Sounder to
initialize itself and calculate a position fix without
knowing your present position. This usually pro-
vides a position fix in 7.5-15 minutes.
If the EZinit prompt has not automatically
appeared on the Satellite Page:
1. Press the
F
key.
Note: If the EZinit prompt appears at any time after
you have initialized the receiver (because satellite sig-
nals are being obstructed by trees, etc.), highlight ‘No
Re-Init’ with the arrow keypad and press ENTER.
To initialize the receiver:
1. If the ‘country’ option is not highlighted, press the
D
key repeatedly to move the field highlight to the ‘coun-
try’ option and press the
F
key.

The EZinit prompt will
automatically appear if the
receiver needs to be initial-
ized. The prompt may also
appear during normal use if
the antenna is shaded.
Use the arrow keypad to
highlight the country,
region, or state of your pre-
sent position from the list
and press ENTER. If the
country is not listed, select
the closest country instead.
