2. Safety Information
- Streamtafier: Brûk allinnich de oantsjutte stroomadapter. Soargje derfoar dat it folumetage komt oerien mei de easken fan jo regio.
- Ventilaasje: Blokkearje gjin fentilaasje-iepeningen. Soargje foar foldwaande luchtstream om it apparaat hinne om oerferhitting te foarkommen.
- Focht: Keep the device away from water, humidity, and liquids. Do not operate with wet hands.
- Pleatsing: Plak it apparaat op in stabyl, flak oerflak. Plak it net tichtby waarmteboarnen of yn direkt sinneljocht.
- Betsjinning: Besykje it apparaat net sels útinoar te heljen of te reparearjen. Lit alle ûnderhâldswurk oer oan kwalifisearre personiel.
- Reiniging: Skeakelje de stroom út foardat jo skjinmeitsje. Brûk in sêfte, droege doek. Brûk gjin floeibere of spuitbussenreinigers.
