（3）Cautionswhenmeasuringdirection
Directioncannotbecorrectlymeasurednearobjectsgeneratingstrongmagnetism.
Keepthiswatchawayfromthefollowingobjects.
Example:Permanentmagnetssuchasamagneticnecklace,metallicdoor,high-voltage
line,elevatedtransitline,electricproductssuchasatelevisionandrefrigerator
Thiswatchcannot correctlymeasuredirectioninmachines suchasatrain, airplane
andautomobile.
Thiswatchcannot correctlymeasure directioninaroom,particularlyina reinforced
concretebuilding.
Measurementerrormaybelargeratplacesnearthenorthpoleorsouthpole.
