WARNING: There is a danger of battery explosion if a lithium battery is
incorrectly replaced. To prevent damage to your computer, be sure the +
side faces up when installing a new battery. Also, be sure you replace the
battery with either a DIGITAL (P/N 12-41474-05), Toshiba (P/N CR2032), or
equivalent 3 V dc lithium battery.
Depending on your locality, your computer’s battery might be considered
hazardous waste. Make sure you follow any state or local statute to properly
dispose of the old battery.

ADVARSEL: Der er fare for, at et lithiumbatteri eksploderer, hvis det
udskiftes ukorrekt. Undgå, at beskadige din computer - HUSK, at + siden
skal vende opad, når du installerer et nyt batteri. Du skal udskifte batteriet
med enten et DIGITAL (delnummer 12-41474-05), Toshiba (delnummer
CR2032), eller tilsvarende 3 V jævnstrøms lithiumbatteri.
Afhængig af dit lokalområde, er det muligt, at din computers batteri betragtes
som farligt affald. Husk, at følge evt. miljølove og lokale bestemmelser, når
du kasserer det gamle batteri.
VAROITUS: Litiumpatterit voivat räjähtää, jos ne asennetaan väärin.
Estääksesi tietokoneesi vaurioitumisen varmista, että patteria asentaessasi
sen positiivinen (+) puoli on ylöspäin. Tarkista myös, että käyttämäsi uusi
patteri on joko DIGITAL (osa no. 12-41474-05), Toshiba (osa no. CR2032)
tai vastaavanlainen 3 voltin tasavirtalitiumpatteri.
Asuinpaikastasi riippuen tietokoneesi patteria voidaan pitää
ongelmajätteenä. Pidä huoli, että hävität vanhan patterin voimassa olevien
lakien ja asetusten mukaisesti.
VARNING! Det kan förekomma en batteriexplosion om ett litium-jonbatteri
byts ut på felaktigt sätt. Förhindra att datorn skadas genom att se till att
plussidan (+) är uppåtvänd när du sätter i ett nytt batteri. Det gamla batteriet
får endast bytas ut mot ett DIGITAL-batteri (artikelnummer 12-41454-05), ett
Toshiba-batteri (artikelnummer CR2032) eller ett motsvarande litiumbatteri
på 3 volt likström.
Datorbatterier anses vara miljöfarligt avfall i många länder. Du måste följa
alla lokala bestämmelser när du avyttrar ett gammalt batteri.
