2 GPSMAP 182/182C Owner’s Manual
BASIC OPERATION > INITIALIZING THE RECEIVER
To graphically initialize the GPSMAP 182/182C:
1. Press MENU twice for the Main Menu. Press up or down
on the ROCKER until the GPS tab is highlighted, and press
MENU one time.
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 determine 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
displays “Ready 2D or 3D” during this process, it is not
necessary to initialize the unit.
The GPSMAP 182/182C 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 has collected the
necessary data and the satellite(s) are ready for use.
When the receiver has collected information from at least three
satellites, the top of the screen displays either “Ready 2D or 3D”,
and the GPSMAP 182/182C is ready for use.
