7.The lamp becomes extremely hot during operation. Allow the projector to cool for approximately 45 minutes prior to removing the lamp assembly for replacement.

9.Never replace the lamp assembly or any electronic components unless the projector is unplugged.

10.Do not place this product on an unstable cart, stand, or table. The product may fall, sustaining serious damage.

11.Do not attempt to disassemble this projector. There are dangerous high voltages inside which may cause death if you should come into contact with live parts.
