2. Installation et configuration
Before attempting installation, ensure the projector is turned off and unplugged from the power source. Allow the old bulb to cool completely if it was recently in use.
Étapes d'installation :
- La sécurité avant tout : Disconnect the projector from the main power supply.
- Compartiment d'accès à l'ampoule : Refer to your projector's specific manual for instructions on how to open the bulb compartment. This usually involves opening a latch or removing a cover.
- Retirer l'ancienne ampoule : Carefully grasp the old bulb (use gloves or a cloth to avoid leaving fingerprints if handling directly) and gently pull it straight out from its socket. The G17Q base is a prong type, so it should slide out.
- Insérer une nouvelle ampoule : Align the prongs of the new Technical Precision bulb with the slots in the projector's socket. Gently push the bulb straight into the socket until it is firmly seated. Do not force the bulb.
- Compartiment sécurisé : Close the bulb compartment cover and secure any latches or screws.
- Test: Plug the projector back into the power source and turn it on to test the new bulb.
