Notes on Using Wireless Connection
Wireless connection function of the projector uses radio waves in the 2.4 GHz / 5.0 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. r
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. f
Industrial, chemical and medical equipment, etc. f
In-plant radio stations for identifying moving objects such as those used in factory manufacturing lines, etc. f
Designated low-power radio stations f
If at all possible, avoid the use of cellular phones, TV sets or radios near the projector. r
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, r
concrete, etc.
Communication is possible through walls and oors made from materials such as wood and glass (except
glass containing
wire mesh), but not through walls and oors made from steel reinforcements, metal, concrete, etc.
Avoid using the projector in locations prone to static electricity. r
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. “Glossary” (

pages 136 – 137)
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 <ON(G)/STANDBY(R)> indicator on the projector changes from lighting in orange to lighting/blinking in red/green,
power on the projector and reconnect to the LAN.
Using the projector outside the country r
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.
Available wireless LAN channels r
The channels (frequency range) that can be used differ according to the country or region. Refer to the table below.
Country or region Standard Channels used Frequency band (Center frequency)
Global
IEEE802.11a/n Passive scanning 5.180 GHz - 5.850 GHz
IEEE802.11b/g/n Passive scanning 2.412 GHz - 2.472 GHz
The frequency and channel differ depending on the country.
The passive scanning is performed by changing radio to the channel being scanned in each country.
Please use the wireless LAN feature in compliance with the laws of each country.
For France only
The wireless LAN feature of this projector shall exclusively be used inside buildings.
