GPSMAP 188/188C/238 Sounder Getting Started Tour

The Garmin GPSMAP 188/188C/238 Sounder is a powerful electronic navigation system that pro-

vides detailed map coverage and convenient control of many advanced features right from the screen
display. This tour is designed to take you through the basic pages and functions of the system using the
simulator mode. Once you’re familiar with the main pages and functions of the unit, refer to the refer-
ence section for instructions on performing speciﬁ c tasks and functions.

The Getting Started Tour assumes that the receiver has been properly installed and initialized, and

you have not changed any of the default unit settings. If you have changed any settings (position
formats, units of measure, etc.), the descriptions and pictures in the tour may not match your
conﬁ guration.

After powering on the GPSMAP 188/188C/238 Sounder, the GPS Information Page appears as the

receiver begins acquiring satellites. From this or any other page, you may also adjust the backlighting.

The GPSMAP 188/188C/238 Sounder’s adjustable screen backlighting is controlled with the

POWER key, and may be adjusted at any time from any page. The backlight can cycle through off,
user-deﬁ ned, and maximum backlight levels by repeatedly pressing the POWER key.

To turn on and adjust the backlighting:

1. Press POWER and the Light window appears.

2. Press POWER again and the user-deﬁ ned level of backlighting activates. You may adjust this level

by pressing UP or DOWN on the ARROW KEYPAD. If you press POWER one more time, the back-
lighting will be at the maximum setting.

3. Press ENTER or QUIT when done.

The backlight will now cycle through off, the user-deﬁ ned, and maximum backlight levels by

repeatedly pressing the POWER key.

A full-screen GPS Information pop-up page is displayed
after you press the ENTER key to acknowledge the
Warning Page. The pop-up page will go away after the unit
gets a position ﬁ x or you press either ENTER or QUIT.
The page can be disabled and enabled on the Pages Tab
(see page 83).
