3. Press and hold the momentary
push-button for approximately 4
seconds, until VAR is displayed,
then release it. (Pressing the
momentary push-button for 8
seconds de-calibrates the
compass—see Compass
Calibration Mode).
4. Press the button to increment the
VAR number to the desired VAR
number. Wait 5 seconds without
button activity and the compass will return to the heading mode.
Note: If there is no button activity for 5 seconds, the compass writes the
displayed zone VAR number to memory and exits Zone Variation Mode
Compass calibration mode
1. Press the momentary push button
and hold it for more than 8 seconds.
After 8 seconds, CAL is displayed,
then release it.
Note: After button release CAL will
be displayed with a heading. The
compass is now de-calibrated and
enters the Initial AutoCal Mode.
2. Drive the vehicle in a tight circle
in a magnetically clean area such as
an open parking lot. Drive at a rate not faster than 15 seconds per circle
(5 MPH).
Note: Look for a parking lot away from buildings, light posts, manhole
covers, sewer and drainage grates and other metallic objects. Some
magnetic objects may be hidden underground. Look for signs of
underground utilities, water mains or other industrial structures. The
parking lot should be level and have a smooth surface. Blacktop is
preferred over cement as a cement surface often contains iron
reinforcing bars or metallic mesh that could interfere with the calibration
process.
• The CAL indication will turn off when the calibration process is
complete, leaving the compass heading on the display.
Note: This process normally takes about 1
1
⁄
2
circles but may take longer
if magnetic noise is present or if the circles are driven too fast.
