impact the lamp life due to the thermal expansion effect. Lamp Spa Mode allows the
projector to refresh the lamp automatically and continuously after shutdown, which
will maintain the electrode to keep it in good condition and extend the lamp life.
To set Lamp Spa Mode, go into the SYSTEM SETUP: Advanced > Lamp
Settings > Lamp Spa Mode menu and press

shutdown. If you want to cancel the Lamp Spa Mode, press
