WIRELESS LAN USAGE PRECAUTIONS
Personal Information (Security-related)
Usage Precautions
●
There is a possibility of interception if you use wireless LAN equipment
due to the use of radio waves regardless of whether you use encryption or
not.
●
Wireless LAN uses radio waves to exchange information between this
product and the wireless router. This means it has the advantage of freely
being able to make a LAN connection if within reach of radio waves. On
the other hand, if the radio waves are within a certain range, they will
reach all locations beyond obstacles (e.g. walls). Therefore, it is possible
your communications may be intercepted and read or illegally intruded
upon.
●
Do not connect to equipment and networks which you are not authorized
to use when setting up your wireless connection.
●
Initialize the settings of this product when disposing it, or transferring it to
a third party.
Others
●
Use this product as regular wireless LAN equipment.
• Do not use this product in hospitals or in/near locations with medical
equipment.
• Do not use this product within aircraft.
• Do not use this product near electronic equipment that handles high-precision
control or weak signals.
Examples of electronic equipment to be careful of:
Hearing aids, pacemakers, re alarms, automatic doors and other
automatic control equipment.
To CONTENTS
En-09
WIRELESS LAN USAGE PRECAUTIONS
●
This is not a guarantee of wireless connection and performance with all
wireless routers and in all residential environments. Radio waves may not
reach or may be interrupted in the following situations.

• Interference with wireless communication equipment using the same
frequency.
• Places where there are magnetic elds from equipment such as microwave
ovens, or static electricity or radio wave interference occurs.
