TO PRESERVE THE QUALITY OF YOUR STOPWATCH
WATER RESISTANCE (10 bar)
Your stopwatch is designed and manufactured to
withstand up to 10 bar, and is suitable for taking baths
and shallow diving, but not for scuba diving.
Do not operate the buttons when the stopwatch is wet or
in water. If used in sea water, rinse the stopwatch in
fresh water and dry it completely.
When bathing with your stopwatch, be sure to observe
the following:
* Do not operate the buttons when the stopwatch is wet
with soapy water or shampoo.
* If the stopwatch is left in warm water, a slight time loss
or gain may be caused. This condition, however, will
be corrected when the stopwatch returns to normal
temperature.
TEMPERATURES
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
temperature. Do not leave your stopwatch in very low
temperatures below –10 C (+14 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.
CHEMICALS
Be careful not to expose the stopwatch to solvents,
mercury, cosmetic spray, detergents, adhesives or paints.
Otherwise, the case, etc. may become discolored,
deteriorated or damaged.
PERIODIC CHECK
It is recommended that the stopwatch be checked once
every 2 to 3 years. Have 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 it.
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 7 years. After that it may decrease in
contrast, becoming difficult to read. Please contact your
AUTHORIZED SEIKO DEALER or SERVICE CENTER if you
wish to have a new panel fitted (guaranteed one year).
