- Press A to confirm the corrected value, and return to normal measurement mode.
For example: If you find the direction which is measured by the watch is not correct, please use other
compass to measure out the northern direction first, then use "12 hour" of the watch to align the
northern direction, press D key to measure compass, if the arrow point direction is 30° of west, you
should input -30°according to above operation method, to measure compass after press A key to confirm,
in the meanwhile, the arrow will point at northern direction, which means correction is complete. If you
do not find any other compass to measure out northern direction, please use manual correction to
measure out northern direction automatically within +/-11°, but please notice that the value must be set
as "00" when you select in the "DEC" digital correction mode.
- The following table indicated the meaning of each acronym for each direction.
Direction Meaning Direction Meaning Direction Meaning
N North NNE North-north-east NE North-east
E East ESE East-south-east SE South-east
S South SSW South-south-west SW South-west

- Preservation
If this watch is magnetized, the definition of the direction sensor will be reduced. Thus please don't put this
watch in a place near a magnet or any object which gives off strong magnetic force. These objects include:
eternal magnet (magnetic necklace, etc.) and home electrical appliance (TV set, computer, washing machine,
refrigerator, etc.).
If you doubt that your watch may have been magnetized, please conduct digital correction and manual
correction in the "Direction sensor correction".
- The reason why the direction measured is incorrect
If the direction is incorrect, please conduct direction correction. If measure direction near strong magnetic
field, such as home electrical appliance, large iron bridge, steel pillar, overhead cable, etc. or measured the
direction in a train or ship, it will result in error. Please move away from the large metal object and measure
the direction once again. Please note that the digital compass can not be used in train or ship.
- Why different results will be produced when measure direction in a same place?
The magnetic force from high voltage cable nearby give interference to the geomagnetic detection by this
watch. Please move away from high voltage cable and do detection once again.
- Why problem occurs when measure direction indoor?
TV set, personnel computer, speaker or other objects will interfere in the geomagnetic detection by this
watch. Please keep away from interferential objects or do detection outdoor. It will be more difficult when
do direction detection within a building made of reinforced concrete. Please note that the direction
detection can not be conducted in train or plane.
- Notice for Digital compass
This watch has a magnetic direction sensor, which can detect geomagnetism. That means the north indicated
by this watch is the magnetic north pole, it is a little different from the real North Pole. The magnetic north
pole is located in the north of Canada, and the magnetic South Pole is located in the south of Australia.
Please note that, when measure using magnetic compass, the more close to the magnetic pole of the earth,
the bigger difference between the magnetic north pole and real North Pole. In addition, some maps marked
with real North Pole (not the magnetic north pole). Thus when using that kind of maps with this watch,
proper adjustment is needed.
- Location measurement
When measure direction near a strong magnetic field, a huge error will be created. Thus the following objects
shall be avoided when measuring direction: eternal magnet (magnetic necklace), metal block (iron door, metal
store ark, etc.), high voltage electrical wire, antenna, home electrical appliance (TV set, personnel computer,
washing machine, refrigerator, etc.).
When in the train, ship or plane, etc. the direction can not be measured correctly.
When in doors, especially in a building made up of many metals, the direction can not be measured correctly.
This is because the metal structure within the building will absorb the magnetic force from the electrical
appliance.
