2. Fiosrachadh Sàbhailteachd

Please read and understand all safety instructions before operating the device. Failure to comply with these instructions may result in electric shock, fire, or damage to the product.

• Ceangail an solar cumhachd ri socaid le talamh an-còmhnaidh.
• Na bi ag obair ann am fliuch no damp cumhachan.
• Dèan cinnteach gu bheil fionnarachadh ceart ann gus casg a chur air cus teasachadh. Na cuir bacadh air na bealaichean-adhair.
• Na fosgail an casing; chan eil pàirtean sam bith a dh’ fhaodas an neach-cleachdaidh a chàradh a-staigh. Thoir sùil air luchd-obrach teisteanasach airson an t-seirbheis.
• Dearbhaich cuir a-steach voltage settings (110V/220V) match your local power supply before connecting.
• Use only the specified power cord and accessories.
• Dì-cheangail an cumhachd mus dèan thu ceanglaichean no dì-cheanglaichean sam bith ris na cinn-uidhe toraidh.
