Getting Started
Initializing the Receiver
To graphically initialize the GPSMAP 182/182C/232:
1. Press the MENU key twice for the Main Menu. Press Up or Down on the ARROW KEYPAD until
the ‘GPS’ tab is highlighted, then press the MENU key once.
2. Using the ARROW KEYPAD, highlight ‘Initialize Position’ and press ENTER/MARK to initialize
the receiver from the map. The Initialize Position Page will appear, prompting you to select your
approximate location with the map cursor.
3. Use the ARROW KEYPAD to move the map cursor and point to your approximate location within
200 miles. If you have diffi culty identifying your position, press and release the IN key to see the
next lower map scale.
4. Once you have determined your approximate location on the map, press the ENTER/MARK key.
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/232 will now begin searching for the appropriate satellites for your region
and should acquire a fi x within a few minutes. When viewing the ‘GPS’ tab on the Main Menu, a signal
strength bar for each satellite in view will appear on the bottom of the page, with the appropriate satel-
lite number under each bar. The progress of satellite acquisition is shown in three stages:
• 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.
Once the receiver has collected information from at least three satellites, the top of the screen will
display either “Ready (2D or 3D)”, and the GPSMAP 182/182C/232 is ready for use.
Point to your approxi-
mate location and press
ENTER/MARK.
A satellite’s strength bars
will turn black when it’s
ready for use.
