How to install BTI PRM25-LAMP

• Power off the projector, unplug it from the power source, and allow the device to cool completely before handling any internal components.
• Remove the projector’s lamp cover and locate the existing lamp module. Carefully unscrew and lift the old lamp out of its housing, avoiding contact with the glass envelope to prevent damage or contamination.
• Handle the new PRM25-LAMP by its housing only. Align the connector pins with the socket and insert the lamp into the housing until it seats securely. Reinstall the mounting screws with steady, even pressure—do not overtighten.
• Replace the lamp cover and plug the projector back in. Power on and allow the lamp to complete its initial startup sequence; give it a moment to reach full brightness before making image adjustments.
• Reset the projector’s lamp timer to reflect the installation of a new bulb. Run a standard test pattern or a typical presentation slide to check brightness, contrast, and color consistency across the screen.
• Dispose of the old lamp in accordance with local regulations and packaging guidelines, and store any unused components in a safe, dry place to prevent damage or contamination.
