device wiring that might have excessive voltage.
For the customers in the Netherlands
Voor de klanten in Nederland
Dit apparaat bevat een MnO2-Li batterij voor memory
back-up.
Raadpleeg uw leverancier indien de batterij toch
vervangen moet worden.
Hoe u de batterijen moet verwijderen, leest u in de
Onderhoudshandleiding.
Gooi de batterij niet weg maar lever deze in als klein
chemisch afval (KCA).
Lever het apparaat aan het einde van
de levensduur in voor recycling, de
batterij zal dan op correcte wijze
verwerkt worden.
Für Kunden in Deutschland
Entsorgungshinweis: Bitte werfen Sie nur entladene
Batterien in die Sammelboxen beim Handel oder den
Kommunen. Entladen sind Batterien in der Regel dann,
wenn das Gerät abschaltet und signalisiert “Batterie
leer” oder nach längerer Gebrauchsdauer der Batterien
“nicht mehr einwandfrei funktioniert”. Um
sicherzugehen, kleben Sie die Batteriepole z.B. mit
einem Klebestreifen ab oder geben Sie die Batterien
einzeln in einen Plastikbeutel.

1-9. Unleaded Solder
Boards requiring use of unleaded solder are printed with a
lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come
printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
m
.Be sure to use the unleaded solder for the printed circuit
board printed with the lead free mark.
.The unleaded solder melts at a temperature about 40 dC
higher than the ordinary solder, therefore, it is recom-
mended to use the soldering iron having a temperature
regulator.
.The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer
time. The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful.
