• The electronic compass uses the Earth’s magnetic field to 

determine direction. The direction readings produced by the 

electronic compass can be different from actual compass readings 

due to environment and temperature.

• Direction readings taken in any of the following locations may result 

in very inaccurate readings.

 

- Near buildings (especially ferro-concrete structures), large metal 

objects (trains, motor vehicles, etc.), high-voltage power lines, or 

overhead wires

 

- Near metal objects (desks, lockers, etc.), household appliances 

(TVs, computers, speakers, etc.), or permanent magnets 

(magnetic necklaces, etc.)

If you suspect a reading error, move away from the above locations 

and try again.
