Timing of replacing the lamp

When the Lamp indicator lights up red or a message appears suggesting it is time to replace the lamp, please install a new lamp or consult your dealer. An old lamp may cause a malfunction in the projector and in some instances the lamp may explode.

If the Lamp or Temp indicator still lights up after turning the power back on, please contact your dealer. See "Indicators" on page 55 for details.
