Batteribyte

Hur man sä tter i och byter ut batterier – När batterierna blir svaga fungerar displayen, men inte skrivaren. Detta visar att det är dags att byta ut batterierna.

1.Sätt strömställaren på “OFF” (av).

2.Ta bort batterilocket genom att föra det i pilens riktning.

3.Sätt tillbaka batterierna. Se till att “+” och “–” märkena på batteriet motsvarar “+” och “–” märkena i batterifacket. Sätt alltid tillbaka de 4 batterierna på samma gång.

4.Sätt tillbaka batterilocket.

Batteri: Manganbatteri AA(eller R6) × 4

Anm.: Det kan hända att räknaren fungerar felaktigt strax efter batteribyte. Ta i så fall ur batterierna, vänta i minst två minuter

och sätt sedan i dem på nytt.

Det kan även hända att utskriften blir felaktig eller att beräkningen förloras om räknaren utsätts för en kraftig stöt eller andra störningar under pågående beräkning. I så fall måste beräkningen utföras på nytt.

NÄ TSTRÖ MSADAPTERNS ANSLUTNING (EXTRA TILLBEHÖ R)

Denna apparat kan också användas med nätström med hjälp av en nätströmsadapter. När du ansluter näströmsadaptern till kalkylatorn växlas strömkällan automatiskt över från batteri till nätström.

Nä tströ msadapter: Modell EA-28A1

Anm.:

Kontrollera alltid att räknaren är avslagen när nättillsatsen ska anslutas eller kopplas ur.

Utför steg 1och 2för att ansluta nättillsatsen.

Utför proceduren i omvänd ordning för att koppla ur nättillsatsen.
