Using The Barometer And Temperature Screens - Magellan iCGRS User Manual

Appendix
Setting the Compass Orientation
As discussed in the previous section, there may come a time that you wish to turn the
compass off and use the GPS Course to determine your heading. (Remember, GPS
Course will only calculate heading when you are moving at a speed greater then 0.5 miles
per hour.)
1. From any screen press
2. Use the arrow pad to highlight "Setup" and press
3. Use the arrow pad to highlight "Compass Orient." and press
4. Use the arrow pad to select "GPS Course" and press
"Magnetic North" turns the compass back on.
5. Press ESC to exit the Setup Menu and return to the last screen you were
viewing.

Using the Barometer and Temperature Screens

In addition to the electronic compass, your SporTrak Color provides you with a "mini-
weather station" with temperature and barometer information.
Accessing the Weather Screen
1. From any screen press
2. Use the arrow pad to highlight "Weather" and press
The Weather Screen is displayed with current temperature and barometer information.
Temperature and barometric information are displayed in a familiar and easy to read
format. The bottom of the display is a graphic of the barometric readings taken over the
last 24 hours. (The SporTrak Color will take barometric readings anytime the compass is
active.)
A brief explanation of the barometer graph is in order at this time. A new bar indicating
your barometric pressure is added to the graph once every 15 minutes. If during the
course of an hour it has taken two readings, it fills in the gap between the readings. If,
however, you have turned the receiver off or do not have enough satellites to compute
altitude (four satellites are needed for altitude computations), and only one reading or less
has been taken in the course of the last hour, there will be gaps in the chart. (See Accessing
Barometer History for more information.)
Calibrating the Temperature and Barometer
This is not a requirement for using the temperature and barometer readings. It simply
makes the readings you have a little more accurate.
