2. Fiosrachadh Sàbhailteachd
Cùm na ceumannan sàbhailteachd a leanas an-còmhnaidh rè stàladh is obrachadh:
- Dì-cheangail an solar cumhachd bhon t-socaid balla mus cuir thu a-steach no mus toir thu air falbh co-phàirtean sam bith.
- Cuir ort strap dùirn an-aghaidh statach gus casg a chur air milleadh sgaoilidh electrostatach (ESD) air co-phàirtean mothachail.
- Handle tempered glass panels with care. Avoid impacts or dropping them, as they can shatter.
- Cùm pàirtean beaga agus sgriothan air falbh bho chloinn.
- Dèan cinnteach gu bheil deagh fhionnarachadh timcheall a’ chùis gus casg a chur air cus teasachadh.
