Introduction
■ Caution concerning interference with 2.4Ghz wireless LAN
When communicating with a 2.4GHz LAN, be careful about the following.
Microwave ovens and other industrial, scientific, and medical equipment, as well as indoor wireless stations (wireless stations
requiring permits) and special low-power wireless stations (wireless stations not requiring permits) used for identifying mobile
units used in plant manufacturing line etc., as well as amateur wireless stations (wireless stations requiring permits) operate in
the frequency band used by this product.
Before using this product, double check that no indoor wireless stations, special low-power wireless stations for mobile unit
identification, or amateur wireless stations are in operation in the vicinity.
If this product should cause harmful electromagnetic interference in an indoor wireless station for identifying a mobile unit,
quickly change the frequency used or stop emitting the electromagnetic signal, then notify the store of purchase and
consult with them about measures for avoiding interference (for example, installing a partition wall).
Besides that, if this product should cause harmful electromagnetic interference in a special low-power wireless station used
for identifying a mobile unit, or in an amateur wireless station, or some other problem occurs, please inquire at the store
from which you made your purchase.

Because the 2.4GHz band frequency used in this product overlaps with medical equipment, microwave ovens and other
industrial and scientific equipment, as well as indoor wireless stations and special low-power wireless stations for identifying
mobile units used in plant manufacturing line etc., electromagnetic interference is possible. Before starting to use this product,
double check that no indoor wireless stations or special low-power wireless stations are operating within the interference range
of this product.
