Notes regarding the wireless LAN
Radio wave in the 2.4 GHz/5 GHz band is used when the wireless LAN connection function of the projector is
used. The license of wireless station is not required, but understand the following when using.
r
Do not use close to other wireless devices.
Following devices may be using radio wave in the same bandwidth as the projector. Using the projector close to
these devices may cause the communication to be disabled or the communication speed to slow down due to
interference of radio wave.
f
Microwave oven, etc.
f
Industrial, scientific, or medical devices, etc.
f
In-plant wireless station for identifying moving vehicles used in the manufacturing lines at a plant
f
Specified low power wireless station
r
Do not use cell phone, television, or radio as much as possible close to the projector.
Cell phone, television, or radio is using radio wave with different bandwidth from the projector, so there is no effect
on the wireless LAN communication or the send/receive on these devices. However, noise may occur in the audio
or video due to the radio wave from the projector.
r
Radio wave for wireless LAN communication does not go through the reinforcing
bars, metal, or concrete.
The projector can communicate through wall or floor made of wood or glass (excluding the glass with metal mesh
embedded), but it cannot communicate through wall or floor made of reinforcing bars, metal, or concrete.
r
Do not use the projector as much as possible in a location where static electricity is
generated.
The communication via wireless LAN or wired LAN may be prone to disruption when the projector is used in a
location where static electricity or noise is generated.
There is a rare case that the LAN connection may not be established due to static electricity or noise. In such
case, turn off the power with the power button on the remote control or the power supply unit of the projector,
remove the source of problematic static electricity or noise, and turn the power of the projector back on.
r
Using the projector outside the country
The wireless LAN function is forbidden when you use the projector outside the country or region where you
purchased it. Note that depending on countries or regions, there are restrictions on the channels and frequencies
at which you can use the wireless LAN.
r
Available wireless LAN channels
The channels (frequency range) that can be used differ according to the country or region.
Please use the wireless LAN feature in compliance with the laws of each country.
