GETTING STARTED
Initialization
The select initialization window will appear, with the ‘select from map’
option highlighted.
1. Press T to initialize the receiver from the built-in worldwide map.
The map page will appear, prompting you to select your approximate
present position with the map cursor.
1. Use the R keypad to move the map cursor to a location close to your present
position. If you have difficulty identifying your exact position, use the bottom
arrow of the
Z
key to zoom in to a lower map scale.
2. Press T to confirm your selection.
The GPSMAP 175 will now begin searching for the appropriate satellites
for your present position and should acquire a fix within a minute or so.
While the receiver searches for satellites, a flashing satellite icon will appear at
the left-hand side of the status bar. A signal strength bar will also appear for
each satellite in view, with the appropriate satellite 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) is ready for use.
Once the receiver has collected information from at least three satellites, the
flashing satellite icon on the status bar will glow steadily, and the GPSMAP
175 is ready for use.
