Do not use the watch in scuba diving or saturation diving.
The various tightened inspections under simulated harsh
environment, which are usually required for watches designed for
scuba diving or saturation diving, have not been conducted on
this watch. For diving, use special watches for diving.
The radio waves emitted from this product may have a
negative impact and cause an accident due to a malfunction.
・ Do not use this product near medical equipment.
The radio waves may affect pacemakers and electric medical
equipment . Do not use it in crowded places such as packed
trains, and inside of medical institutions.
・ D o not use this product near automatic control devices such as
automatic doors and fi re alarm systems.
Set this product to the in-fl ight mode in places such as
inside of airplanes in which emission of radio waves is
limited in order to not use the communication function.
The radio waves emitted from this product may have a negative
impact on other equipment.

When water runs directly from a faucet onto the
watch, very high water pressure is applied. The
measurement accuracy of the sensor to measure
pressure temporarily degrades, and the values of
altitude and atmospheric pressure may fluctuate. If
very high water pressure is applied to the body of
the watch, wait for about 10 minutes or more until
the measurement accuracy of the pressure sensor
recovers and then measure again.
Do not pour running water directly from faucet onto
the watch.
The water pressure of tap water from a faucet is high enough to
degrade the water resistant performance of a water resistant
watch for everyday life.

CAUTIONS
CAUTIONS
This product can be used only in Japan.
Since some other countries have limitation on use of radio waves,
the person who uses this product may face penalties for usage.
Note that if this product is used near devices that
emit strong magnetism or in places with a strong
magnetic field, an error may occur in measurement
of the direction, etc., or it may become impossible to
measure with this device.
In addition, a correct measurement is impossible
in environments with metal, etc., in buildings that
block the earth s magnetism. Take measurements
in environments where there are no metal shields
around.
