2. Fiosrachadh Sàbhailteachd
Sàbhailteachd laser: This device emits a Class II laser. Do not stare directly into the laser beam or direct it at other people. Avoid pointing the laser at reflective surfaces. Always operate the device in a safe manner to prevent eye injury.
Sàbhailteachd bataraidh:
- Use only AAA alkaline batteries as specified.
- Na bi a’ measgachadh bataraidhean sean is ùr, no diofar sheòrsaichean bataraidhean.
- Dèan cinnteach gu bheil bataraidhean air an cur a-steach leis a’ phòlaireachd cheart.
- Thoir air falbh bataraidhean mura tèid an inneal a chleachdadh airson ùine mhòr gus casg a chur air aodion.
- Cuir às do bataraidhean cleachdte a rèir riaghailtean ionadail.
Sàbhailteachd Coitcheann:
- Cùm an inneal air falbh bho chlann.
- Na feuch ri an inneal atharrachadh no a thoirt às a chèile. Cha bu chòir càradh a dhèanamh ach le luchd-obrach ùghdarraichte.
- Seachain an inneal a nochdadh gu fìor theodhachd, taiseachd, no solas dìreach.
