Precautions
Notes on Handling and Storage
• Do not store in locations with high temperatures or high humidity. It
may in particular be damaged or deformed if left in a vehicle with the
windows shut, or placed it locations with unusually high temperatures
for extended periods such as in direct sunlight.
• Do not get it wet. This may cause malfunctions to occur.
• Do not use near microwave ovens. Wireless communication may be
interrupted by electromagnetic interference generated by microwave
ovens.
• Do not drop it, subject it to shocks, or place heavy objects on it.
Frequency Precautions
The frequency band for this unit is 2.4 GHz/5 GHz. This frequency range
is the same frequency bandwidth as industrial, scientific, and medical
devices such as microwave ovens and mobile unit identification (RF-ID)
systems (licensed premises radio stations and unlicensed specified low-
power radio stations) used in factory production lines. Before using this
unit, check that there are no radio stations for mobile unit identification or
specified low-power radio station premises nearby. In the event that this
unit should interfere electromagnetically with the premises of a radio
station used for mobile unit recognition, cease use immediately and stop
generating the electromagnetic field. Contact your local dealer or the
nearest address provided in the Support and Service Guide supplied with
the projector if this unit interferes electromagnetically with a special low-
power radio station used for mobile unit identification or causes similar
problems.
Wireless Telegraphy Act Regulations
The following acts are prohibited by the Wireless Telegraphy Act.
• Modifying and disassembling (including the antenna)
• Removing the label of conformance
• IEEE 802.11a (5 GHz band) external use
International Travel Precautions
Wireless devices are designed to conform to the channel and frequency
limits of the country they are intended to be used in. This unit is based on
the specifications of the country of sale. If this unit is used outside the
country of sale, check with a local dealer for more information.

Notes on Security when Using Wireless LAN
(Important information on customer rights (maintaining privacy))
The advantage of using a wireless LAN over a LAN cable is that, because
information is exchanged using radio signals, you can easily connect to
the network if you are within range of the radio signals. A disadvantage of
this is that within a certain range, the electromagnetic signals can pass
through barriers such as walls, so that if security countermeasures are not
implemented in some way, problems such as the following may occur.
• Communicated data can be intercepted
A third party may be able to receive wireless transmissions without
authorization, and they could obtain personal information from these
transmissions such as IDs, passwords, or credit card numbers, or they
could intercept the contents of personal e-mail messages.
• Unauthorized access to the network
A third party could access an individual or intra-company network
without permission and carry out any of the following activities.
- Retrieve personal data or other secret information (information
leakage)
- Pose as another user and send inappropriate data (impersonation)
- Overwrite the contents of intercepted data and resend it (falsification)
- Introduce a computer virus which could cause data loss or system
crashes (damage)
Initially, the possibility that such problems could occur through settings
concerning the security of the wireless LAN product and by using the
product are decreased, because the wireless LAN card and the access
point have security measures to deal with these problems. We recommend
that you use this product after making security settings using your own
judgment and assuming full responsibility, and with your full
understanding of problems that may occur if you do not make any security
settings.
See the documentation supplied with the projector for information on
security settings.

Steps for Connecting in "Quick Connection Mode"
When this unit is installed in the projector, you can project computer
images by wirelessly connecting the projector with a computer over a
network.
Type of Network Connection
You can use the following two methods to connect a computer and the
projector over a network by using EMP NS Connection found on the
EPSON Projector Software for Meeting & Presentation CD-ROM
supplied with the projector.
f"Advanced Connection Mode"
"Advanced Connection Mode" is an infrastructure connection, and
connects to an existing network system via a network cable.
When this unit is installed in the projector, you can connect to a network
via a wireless LAN access point. If the wireless LAN access point is
WPS (Wi-Fi Protected Setup) compatible, you can easily connect the
projector to the access point and make security settings. See the
documentation supplied with the projector for more details.
When connecting in "Advanced Connection Mode" you can use the
network in the following ways.
• From a conference room, you can open and project a file stored on a
computer or file server in another room.
• You can use the Internet.
• You can monitor and control projectors on a network from the
computer.
f"Quick Connection Mode"
"Quick Connection Mode" is a mode for executing wireless LAN only.
"Quick Connection Mode" temporarily assigns the projector's SSID to a
computer creating an ad hoc connection, and after disconnecting
restores the computer's network settings.
"Quick Connection Mode" has the following advantages.
• You can easily connect a computer to the projector and project images
from the computer without making network settings.
• This lets you connect easily without a connector cable, and you can
connect even if the projector and the computer are at remote locations.
This guide explains how to connect to a computer in "Quick Connection
Mode" and project computer images.
