If it is necessary to take out the battery, keep it out of the reach of
children. If a child swallows it, consult a doctor immediately.
Never short-circuit, heat or otherwise tamper with the battery, and
never expose it to fire. The battery may burst, become very hot or
catch fire.
The battery is not rechargeable. Never attempt to recharge it, as this
may cause battery leakage or damage to the battery.

NOTES ON THE STRAP

The stopwatch has a strap for wearing the stopwatch around your
neck. Take good care lest it should be caught by something near you
or wind around your neck.
Please also note that the strap may damage your clothes, or injure
your hands, neck or other parts of your body.

TO PRESERVE THE QUALITY OF YOUR STOPWATCH

WATER RESISTANCE (3 bar)
Your stopwatch is designed and manufactured to withstand up to 3 bar, such as
accidental contact with splashes of water or rain, but it is not designed for swimming
or diving. Do not operate the buttons when the stopwatch is wet or in water.
TEMPERATURES
+50°C
If the stopwatch is left in direct sunlight for a long time, the display may become
black, but this condition will be corrected when the stopwatch returns to normal
– 5°C
temperature.
Do not leave your stopwatch in very low temperatures below –5°C (+23°F) for a
long time since the cold may cause:
a. a slight time loss or gain.
b. the change of digits to become slow.
c. the display light to dim.
However, the above conditions will be corrected when the stopwatch returns to
normal temperature.
SHOCKS
Do not subject it to violent shocks.
MAGNETISM
Your stopwatch will not be affected by magnetism.

detergents, adhesives or paints. Otherwise, the case, etc. may become discolored,

It is recommended that the stopwatch be checked once every 2 to 3 years. Have
2 - 3
Years
your stopwatch checked by an AUTHORIZED SEIKO DEALER or SERVICE
CENTER to ensure that the case, buttons, gasket and crystal seal remain intact.
PRECAUTION REGARDING CASE BACK PROTECTIVE FILM
If your stopwatch has a protective film and/or a sticker on the case back, be sure
to peel them off before using your stopwatch.
STATIC ELECTRICITY
The IC (Integrated Circuit) used in your stopwatch will be affected by static
electricity which may disturb the display. Keep your stopwatch away from close
contact with objects such as TV screens which emit strong static electricity.
LIQUID CRYSTAL PANEL
The normal life expectancy for a liquid crystal panel is approximately 5 years.
