is inserted atthe factory, its actuallifeonce in your possession maybe less than
the specified period.
The seal pasted onthe watch case backshows the date that the battery wasin-
serted atthe factory, and thus helps to determinewhen the batteryshould be
replaced. Be sure to replace the battery as soon as possible to prevent any possible

TO PRESERVE THE QUALITY OF YOURWATCH AND
KEYBOARD
• NON-WATERRESISTANT
Yourwatch and keyboard arenot waterresistant, and care should be taken notto
expose them to water ora large quantity of perspiration.
•If theybecome wet with water or perspiration,wipethemcompletely dry with
a highlyabsorbent cloth.
•Donot operate anyofthe buttonswhen the watch and keyboard are wet.
•A little amount of moisture exists inthe watch, andthe crystal may become
blurred ifthe outside temperature is lower than that inside the watch. Such a
temporary blur will not cause any malfunction, but if it does not disappear,
consult an AUTHORIZEDSEIKODEALER.
•TEMPERATURES
YourDATA-2000 is preadjusted to function with stable accuracy whenworn
onthe wrist ata normaltemperature range (5°C ~ 35°C).
• Extremelyhigh temperatures
Care should be taken notto exposeyourDATA-2000 toa hightemperature
over 60°C. Keep it awayfromdirectsunlight ora hot place. Ifitis left in such
a place:
"The digitaldisplay may becomeblack, but this condition will disappear with-
outany aftereffectwhen the temperaturereturns to normal.
*Itmay cause an electrolyte leakage or shorten the battery life.
• Extremely low temperatures
Donot leave yourDATA-2000 ina coldplace fora long time. Ifitis left in
such a place fora long time:
*A smallamount of time loss/gain may occur.
*The change ofthe digits may becomeslow.
The normalperformance ofthe watch,however, will returnwhen the tem-
perature returns to normal.
The product works down to -10°C.
•SHOCKS
Light sportsactivities will not damageyourproduct.However, be careful notto
drop the watch andthe keyboard orhit themagainst any hard surfaces.
• MAGNETISM
Yourwatch by itself will notbe affected by magnetism.However, itmaybe
adversely affected by magnetismwhendata is transmittedfrom the keyboard.
• CHEMICALS
Be careful notto expose your DATA-2000 to chemicals,solvents such as alcohol
and gasoline, or mercury(i.e. from a brokenthermometer) since they may damage
the product.
• CARE OF CASE AND BRACELET
Dust and moisture onthe case and bracelet may cause rust. Wipe them off with
a soft, highly absorbent cloth.
14

•TO KEEP THE KEYBOARD IN GOOD CONDITION
Keep dustaway from the keyboard. If dustaccumulates,wipe itoff with a soft,
dry cloth.
• PERIODICCHECK
Itis recommended that the watch be checked atthe time ofthe battery replace-
ment or,at most, onceevery 2 to3 years.Have your watchchecked byanAU-
THORIZEDSEIKODEALER or SERVICECENTER to ensure that the case,
buttons,gasket, and crystal seal remain intact.
