Preparing for measurement
▪ Check whether you are carrying or wearing objects that could interfere with compass calibration.
– Examples: glasses with metal frames, rings, wristwatches, smartphones, belt buckles, helmets, etc.
▪ Place all objects that could interfere with magnetic waves elsewhere before compass calibration.
10.2 Performing compass calibration (Chicken Dance)
The Chicken Dance icon appears in the Measurement menu/HUD screen 1 to prompt compass calibration.
Compass calibration should be performed at the next opportunity. This process occurs in two stages:
▪ Various rotating motions will need to be performed with the VECTOR X (see Fig. 1).
▪ The VECTOR X will then need to be placed on a horizontal surface in various positions (see Fig. 2).
Procedure
1. Find a suitable location.
2. If necessary, turn the VECTOR X back on by briefly
pressing the Measurement button once.
3. Hold the VECTOR X in front of your body, horizon-
tally and in the neutral position.
4. Rotate the VECTOR X in each of the directions
shown, one after the next (see Fig. 1).
5. Perform each rotating motion continuously for
about two seconds.
6. Bring the VECTOR X back to the neutral position
before performing the next rotating motion.
7. Proceed with the second stage of compass cali-
bration after completing the rotating motions.
