Important Information

About High Altitude mode

• Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately 5500 feet/1600 me-

ters or higher.

Using the projector at altitudes approximately 5500 feet/1600 meters or higher without setting to [HIGH ALTI-

TUDE] can cause the projector to overheat and the protector could shut down. If this happens, wait a couple

minutes and turn on the projector.

• Using the projector at altitudes less than approximately 5500 feet/1600 meters and setting to [HIGH ALTITUDE]

can cause the lamp to overcool, causing the image to ﬂicker. Switch [FAN MODE] to [AUTO].

• Using the projector at altitudes approximately 5500 feet/1600 meters or higher can shorten the life of optical

components such as the lamp.

Caution

The radio waves used by the USB Wireless LAN Unit pass through the wood or glass used in normal homes (but

not through window panes with built-in metallic mesh).

The radio waves do not pass through iron reinforcing bars, metal or concrete, however, so the USB Wireless LAN

Unit cannot be used for communicating through walls or ﬂoors made with these materials.
