Setup of a Cooling Fan Speed
When using this projector in the place where altitude is high, we recommend you to set a cooling fan�s speed as �HIGH�. It is because the cooling efficiency of a projector falls and the temperature inside a projector rises easily in such a place, since the density of air becomes low.

Setting Method of Cooling Fan Speed
1. Select the �FAN SPEED� on the OSD using button � � by the SERVICE MENU.

The �HIGH� mode makes the fan noisy than �NORMAL� mode. The recall of factory setting sets the fan speed to �NORMAL� mode. You must set the fan speed after recall of factory setting if you need �HIGH� mode.
