2. Faisnéis Sábháilteachta
Lean na réamhchúraimí sábháilteachta seo a leanas i gcónaí le linn suiteála agus oibríochta:
- Dícheangail an soláthar cumhachta ón asraon balla sula suiteálann tú nó sula mbaintear aon chomhpháirteanna.
- Caith strap láimhe frithstatach chun damáiste urscaoilte leictreastatach (ESD) do chomhpháirteanna íogaire a chosc.
- Handle tempered glass panels with care. Avoid impacts or dropping them, as they can shatter.
- Coinnigh páirteanna beaga agus scriúnna ar shiúl ó leanaí.
- Cinntigh aeráil cheart timpeall an cháis chun róthéamh a chosc.
- Do not attempt to modify the case structure, as this may void the warranty and pose safety risks.
