About declination correction

Earth is a large magnet that has the north pole as the S pole, and the south pole as the N pole, and the magnetism that the Earth has is called “geomagnetism”. Due to the effects of “geomagnetism”, a discrepancy in angle occurs between the north that the magnetic compass points to (magnetic north) and the correct north (true north).

This discrepancy in angle is called “declination angle”.

The compass that is built-in to this unit corrects the “declination angle” based on the latitude/longitude obtained by GPS positioning, so that it points to “true north”. ••Since moving may change the degree of declination depending on the place,

we recommend that you set [GPS Setting] to [ON], and frequently update your current latitude/longitude.

●●If measurements are taken with this unit upside down, it may be unable to take measurements correctly.

●●In places with weak geomagnetism, the position measurement may be affected. ●●If objects such as the following are nearby, this unit may be unable to take

measurements correctly.

••Permanent magnets (metals like magnetic necklaces)/metals (metal desks, lockers)/ high-voltage lines or wirings/electrical home appliances (such as TVs, PCs, cell phones, speakers)

●●In places such as the following, this unit may be unable to take measurements correctly.

••Automobiles/trains/ships/airplanes/indoors (if the steel frames are magnetized)
