2. Sikkerhetsinformasjon
Følg alltid følgende sikkerhetsregler under installasjon og drift:
- Disconnect the power supply from the wall outlet before installing or removing any components.
- Bruk en antistatisk håndleddsstropp for å forhindre skade på sensitive komponenter fra elektrostatisk utladning (ESD).
- Handle tempered glass panels with care. Avoid impacts or dropping them, as they can shatter.
- Hold små deler og skruer unna barn.
- Sørg for tilstrekkelig ventilasjon rundt kabinettet for å forhindre overoppheting.
- Do not attempt to modify the case structure, as this may void the warranty and pose safety risks.

5. Bruk av PC-en
Once all components are installed and cables are connected, replace the side panels. Connect your monitor, keyboard, mouse, and power cable. Press the power button on the case to start your system. Ensure all fans are spinning and components are receiving power.
6. Vedlikehold
Regelmessig vedlikehold bidrar til å sikre optimal ytelse og levetid for PC-komponentene dine.
- Støvrengjøring: Periodically clean dust filters and internal components using compressed air. The DS900 Air features mesh panels that help filter dust.
- Luftstrøm: Ensure no obstructions block the intake or exhaust vents of the case.

7. Feilsøking
Hvis du støter på problemer med PC-en din, bør du vurdere følgende vanlige feilsøkingstrinn:
- Ingen strøm: Check all power connections, including the PSU to the wall, PSU to motherboard, and front panel power switch cable to the motherboard.
