The GARMIN GPSMAP 175 is a powerful electronic
charting/navigating system that provides detailed chart coverage and
convenient control of many advanced features right from the map 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 reference section for
instructions on performing specific 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 configuration.
To turn the GPSMAP 175 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.
2. Once the self test is complete, press the T key to acknowledge the
mariner’s warning.
The satellite status page will appear, and the receiver will begin to acquire
satellites. From the status page, you may also quickly adjust the screen
contrast and backlighting.
To adjust the screen contrast:
1. Increase the screen contrast by pressing the right arrow of the R keypad.
2. Decrease the screen contrast by pressing the left arrow of the R keypad.
3. Press the T key to finish.
The GPSMAP 175’s three-level screen backlighting is controlled with the
P key, and may be adjusted at any time from any page.
To turn on and adjust the backlighting:
1. Press the P key repeatedly until backlighting is at the desired level
(off, 1, 2, or 3).
