5.3 CALIBRATING THE COMPASS
A compass calibration should be done whenever the Observer is exposed to a strong magnetic
source, extreme cold weather, the battery is replaced, or you suspect that other environmental
conditions have affected the compass readings. If you notice that the compass is not showing

ring on the outer circumference light (Fig. 5.6).
4. Hold the Observer level and slowly rotate the device in a full clockwise or counter-clock-

calibration process. This is simple to accomplish. For example, place the Observer on an
over-turned drinking glass on a table.
5. Within a minute of completing a full circle, the Observer will inform you whether the cali-
