Zone Variation Change Procedure
The difference between magnetic north and geographical north is known as variance. In some areas, this difference can sometimes be great enough to cause false compass reading.
Follow these instructions to set the variance for the particular location if this happens:
- Push "COMP" switch for more than 3 seconds. The current zone number will appear in the display.
- Find the current location and variance one number on the zone variation chart.
- Push "COMP" switch until the new zone number appears in the display. After stopping pushing the switch in, the display will show a compass direction within a few seconds.
