NOTICE

This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interf erence in whic h case th e user will be re quired to co rrect the interfere nce at
his own expense.

This equipment complies with FCC radiation exposure limits set forth for at
uncontrolled equipment. This equipment should be installed and operated with
minimum distance at least 20cm between the radiator and persons
body(excluding extremities: hands, wrists, feet and legs) and must not be co­located or operated with any other antenna or transmitter.

We, Nagano Japan Radio Co., Ltd., hereby declare that Wireless LAN, model NJT­475 is in compliance with the essential requirements and other relevant
provisions of Directive 1999/5/EC.

1.About this Equipment

1.1 Function

This wireless LAN, NJT-475 is intended to use for replacing an Ethernet cable
connection(i.e. wired networks) with wireless networks. A signal, so called as
packet data, which runs in the Ethernet cable is send by wireless as it is, so
that a change to wireless LAN can be realized without any relation with type o f
OS or model of the terminal equipment.

By changing into a wireless communication, following advantages are realized
compared with a wired communication.

1). Low cost of network construction

2). Available while moving.

3). Changing an office layout with an arrangement of OA equipment is easy.

4). LAN in a historical or tenant building where the cable laying is restr icted is

available.

5). LAN connection between buildings across a thoroughfare is possible.

1.2 Features

• Plug and Play

Wireless LAN is easily available to everybody by only connecting an
Ethernet cable to your terminal equipment, such as a personal computer
or workstation, and switch on. Also a troublesome software installation is
not needed.

• Ethernet compatib le in t erface

Connecting to an international standard LAN of IEEE802.3(Ethernet) is
possible without any additional work or items. For customers who have
used a wired LAN, wireless LAN can be realized by simply co nnecting the
wireless LAN adapter to your existing equipment.

• Data reliability

Since the packet data in an Ethernet is sent as it is, the data is reliable
and does not affect on higher layers. Therefore it make possible to change
into wireless communication without any modification of an existing
applicat ion sof t wa re .

• Applicab le t o multi-vendor

This wireless LAN adapter can be connected to any kind of terminal
equipment(P.C. , work station) without any relation to the manufacturer or
model of the terminal equipment. Also a troublesome working of the
software installation is not to be required when connecting the network.
Even if the OS of the terminal equipment is changed, it can be used as it
is.

• High-speed data transmitting

With adopting the radio communication system, pursuant to international
standard of IEEE802.11b, it makes possible to high-speed data
transmitting with a maximum speed of 11 Mbps, which equals to the
wired LAN in transmitting speed.

• Bridge function
