WARNING
NOTES ON THE BATTERY
● Do not remove the battery from the stopwatch.
● 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 it 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 (5 bar)
Your stopwatch is designed and manufactured to withstand up to 5
bar, such as accidental contact with splashes of water or rain. Do not
operate the buttons when the stopwatch is wet or in water.
● 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 -10ºC
(+14ºF) 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).

repeatedly one after the other.
• Each Timer 1 and Timer 2 can be set for any desired amount of time from 10 seconds up to 99 hours,
59 minutes and 59 seconds in one-second increments.
