The compass ring is an electronic compass that
functions like a magnetic compass when you are
stationary. When you are moving and reach a pre-set
speed, it uses data from the GPS receiver to maintain
your heading. When you stop (after a pre-set time), it
again operates like a magnetic compass. The compass
ring is especially helpful when using a paper map or
chart with your Vista Cx for navigation. When the
electronic compass is on, a compass icon appears
in the status bar.
Using the Electronic Compass
When you press and hold the Quit key the electronic
compass turns off, it stays off until you press and hold
the Quit key to turn it on again. However, sometimes
when you turn the electronic compass on, the Vista
Cx overrides the compass and uses the GPS receiver
to track your heading. It also uses the GPS receiver
when you are moving, but only when you are moving.
When stationary or moving slowly you must use the
electronic compass for headings. You can customize
the criteria for switching between the electronic
compass and the GPS as explained on page 50.
To turn the electronic compass on or off:
1. Press and hold the Quit key to turn the
electronic compass on or off. The Compass
Icon appears in the status bar when the
electronic compass is on. When you are not
using the electronic compass, turn it off to
conserve batteries. When it is turned off, the
unit uses the GPS receiver for navigation.
2. Hold the Vista Cx level to get an accurate
electronic compass reading. A “Hold Level”
message appears if you are not holding
the electronic compass correctly, or if it is
not calibrated. (See the following page for
calibration instructions.)
Setting the speed and time for Compass
Auto On and Off:
1. Press the Menu key twice to open the Main
Menu.
2. Highlight Setup, and press Enter to open the
Setup Menu.
3. Highlight the Heading icon, and press Enter to
open the Heading Setup Page.
4. Highlight the Switch to compass heading
when below field, and press Enter.
