Notes on Using Wireless Connection
Wireless connection function of the projector uses radio waves in the 2.4 GHz band.
A radio station license is not required, but be sure to read and fully understand the following items before use.
Do not use near other wireless equipment.
The following equipment may use radio waves in the same band as the projector.
When the projector is used near these devices, radio wave interference may make communication impossible,
or the communication speed may become slower.
Microwave ovens, etc.
•
Industrial, chemical and medical equipment, etc.
•
In-plant radio stations for identifying moving objects such as those used in factory manufacturing lines, etc.
•
Designated low-power radio stations
•
If at all possible, avoid the use of cellular phones, TV sets or radios near the projector.
Cellular phones, TV sets, radios and similar devices use different radio bands from the projector, so there
is no effect on wireless communication or the transmission and reception of these devices. However, radio
waves from the projector may produce audio or video noise.
Wireless communication radio waves cannot penetrate steel reinforcements, metal,
concrete, etc.
Communication is possible through walls and floors made from materials such as wood and glass (except
glass containing wire mesh), but not through walls and floors made from steel reinforcements, metal,
concrete, etc.
Avoid using the projector in locations prone to static electricity.
If the projector is used in a location prone to static electricity, such as on a carpet, the wireless LAN
or wired
LAN connection may be lost.

If this happens, eliminate the source of static electricity or electromagnetic noise and reconnect to the
wireless LAN or wired LAN.
In rare cases static electricity or electromagnetic noise may make it impossible to establish a connection to
the LAN.
If this happens, press the power button on the remote control or on the projector to power off the projector
temporarily.
After the cooling fan stops operating (after <ON(G)/STANDBY(R)> indicator on the projector changes from
blinking in orange to lighting in red), power on the projector and reconnect to the LAN.
Using the projector outside the country
It is forbidden to take the projector outside the country or region where you purchased it, so use it only in
the said country or region. Also, note that depending on countries or regions there are restrictions on the
channels and frequencies at which you can use the wireless LAN.
