INTRODUCTION > WARNINGS AND CAUTIONS
Warning
Failure to avoid the following potentially hazardous situations could
result in an accident or collision resulting in death or serious injury.
When navigating, carefully compare information displayed on the
GPSMAP 198C Sounder to all available navigation sources, including
information from visual sightings, and maps. For safety, always resolve any
discrepancies or questions before continuing navigation.
Use the electronic chart in the GPSMAP 198C Sounder only to facilitate,
not to replace, the use of authorized government charts. Official
government charts and notices to mariners contain all information needed
to navigate safely.
WARNING: This product, its packaging, and its components contain chemicals known to the State of California to cause cancer, birth defects, or reproductive
harm. This Notice is being provided in accordance with California’s Proposition 65. If you have any questions or would like additional information, please refer
to our Web site at http://www.garmin.com/prop65.
Caution
Failure to avoid the following potentially hazardous situations may
result in injury or property damage.
Use the GPSMAP 198C Sounder only as a navigational aid. Do not
attempt to use the GPSMAP 198C Sounder for any purpose requiring
precise measurement of direction, distance, location, or topography.
The Global Positioning System (GPS) is operated by the United States
government, which is solely responsible for its accuracy and maintenance.
The government’s system is subject to changes which could affect the
accuracy and performance of all GPS equipment, including the GPSMAP
198C Sounder. Although the GPSMAP 198C Sounder is a precision
navigation device, any navigation device can be misused or misinterpreted
and, therefore, become unsafe.
Map Data Information: One of the goals of Garmin is to provide customers with the most complete and accurate cartography that is available to us at a
reasonable cost. We use a combination of governmental and private data sources, which we identify in product literature and copyright messages displayed to the
consumer. Virtually all data sources contain inaccurate or incomplete data to some extent. This is particularly true outside the United States, where complete and
accurate digital data is either not available or prohibitively expensive.

BASIC OPERATION
Initializing the Receiver
The first time you turn on the GPSMAP 198C Sounder, the receiver
must be given an opportunity to collect satellite data and establish
its present location. To ensure proper initialization, the GPSMAP
198C Sounder is shipped from the factory in AutoLocate Mode.
Before you initialize, make sure the GPSMAP 198C Sounder unit
and antenna are correctly installed on your vessel according to the
instructions in the “Appendix.” Install the antenna in a location
with a clear and unobstructed view of the sky.
A full-screen GPS Information Page is shown after you press
ENTER to acknowledge the Warning Page. The page goes away
after the unit gets a position fix or you press either ENTER or
QUIT. The page can be disabled and enabled on the
Main Menu—Pages tab (see page 63).
BASIC OPERATION > INITIALIZING THE RECEIVER
To turn on the GPSMAP 198C Sounder:
1. Press and hold the POWER key until the power tone
sounds, then release the POWER key. The Warning Page
appears while the unit conducts a self-test.
2. When the self-test is complete, press ENTER to agree and
acknowledge the warning.
The GPS Information Page appears as the receiver begins acquiring
satellites.
To turn off the GPSMAP 198C Sounder:
1. Press and hold the POWER key for about two seconds,
until the screen is blank.
2. When the screen is blank, release the POWER key.

BASIC OPERATION > INITIALIZING THE RECEIVER
To graphically initialize the GPSMAP 198C Sounder:
1. Press MENU twice for the Main Menu. Press up or down
on the ROCKER until the GPS tab is highlighted, and then
press MENU once.
2. Using the ROCKER, highlight Initialize Position, and press
ENTER. The Initialize Position Page appears, prompting
you to select your approximate location with the map
pointer.
3. Use the ROCKER to move the map pointer to your
approximate location within 200 miles. If you have difficulty
identifying your location, press and release the IN key to
see the next lower map range.
4. After you have determined your approximate location on the
map, press ENTER.
NOTE: This does not calibrate the unit in any way, but
rather helps to speed up the initial satellite acquisition. If the
unit shows “Ready 2D or 3D” during this process, it is not
necessary to initialize the unit.
The unit now begins searching for the appropriate satellites for
your region and should acquire a fix within a few minutes. When
viewing the GPS tab on the Main Menu, a signal strength bar for
each satellite in view appears on the bottom of the page, with the
appropriate satellite number under each bar.
• No signal strength bars—the receiver is looking for the
satellites indicated.
• Hollow signal strength bars—the receiver has found the
indicated satellite(s) and is collecting data.
• Solid signal strength bars—the receiver is ready to use.
When the receiver has collected information from at least three
satellites, the top of the screen shows either “Ready 2D or 3D”, and
the GPSMAP 198C Sounder is ready for use.
