WARNING: To avoid burns, allow the projector to cool for at least 60 minutes before you replace the lamp. Never extract the lamp housing while the projec- tor is operating.

WARNING: Be extremely careful when removing the lamp housing. In the unlikely event that the bulb ruptures, small glass fragments may be generated. The lamp mod- ule is designed to contain these fragments, but use caution when removing the lamp module.
