Handling Precautions (2)
注意
1. ABOUT THIS PRODUCT
Do not use the watch for 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.
・
Do not use this product near automatic control devices
such as automatic doors and fire alarm systems.
In the places where use of radio waves is restricted,
such as in airplanes, turn off wena3 to disconnect
the communication between the watch head and
wena3.
The radio waves emitted from this product may
adversely affect other devices.
Do not push the buttons when the watch is wet.
Water may get inside of the watch.
※
If the inner surface of the glass is clouded with
condensation or water droplets appear inside of the
watch for a long time, the water resistant performance
of the watch is deteriorated. Immediately consult
the retailer from whom the watch was purchased or
SEIKO CUSTOMER SERVICE CENTER.
Do not leave moisture, sweat and dirt on the watch
for a long time.
Be aware of a risk that a water resistant watch may
lessen its water resistant performance because of
deterioration of the adhesive on the glass or gasket, or
the development of rust on stainless steel.
Do not wear the watch while taking a bath or a sauna.
Steam, soap or some components of a hot spring
may accelerate the deterioration of water resistant
performance of the watch.
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.
