NOTES
After entering the compass measurement mode, the measure-
ment will stop after 30 seconds. In the last 30 seconds, it will
lock up and exit this mode, and then return back to time mode.
After entering air pressure, temperature and weather forecast-
ing measurement mode, it will measure once every second.
And it will return back to time mode if without keystroke
operation for 1 minute.
Entering height and temperature measurement mode, it will
measure data once every 5 seconds within rst 3 minutes, and
measure once every 2 minutes after the rst 3 minutes. It will
not exit this mode.
In correction mode, press B key to exit. If displaying “ER-
ROR”, which means correction error. If displaying “DONE”,
which means that the correction is correct.
In setting mode, the set item will blink every 1HZ. It will exit
the setting mode if no keystroke operation within 1 minute.
When above the measurement range, HI will display. When
under the measurement range, Lo will display.
Weather forecast measurement method: estimate the weather
every hour (estimate the weather according to the air pressure
diversication within the former 4 hours). If air pressure value
goes up gradually,it indicates that the weather will turn better. If
the air pressure value goes down gradually, it indicates that the
weather will turn bad. There are 4 kinds of weather status (from
good to bad): Fine, Cloudy, Overcast Sky, Rain.
Notice for Digital compass
This watch has a magnetic direction sensor, which can detect
geomagnetism. That means that 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 those kind
of maps with this watch, proper adjustment is needed.
Location measurement
When measure direction near a strong magnetic eld, 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, personal 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 cannot be measured cor-
rectly. This is because the metal structure within the building
