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.

Built-in 2.4GHz band (IEEE802.11b / IEEE802.11g) wireless LAN functions
Usage frequency band: Wireless equipment using the 2.4GHz band
Transmission method:
DSSS OFDM
Modulation:
DQPSK DBPSK CCK BPSK QPSK 16-QAM 64-QAM
Assumed interference distance: 40m max.
Frequency modulation advantages: The entire bandwidth can be used to avoid the
frequency bands of indoor wireless stations and special low-power wireless stations used for
identifying mobile units, as well as amateur wireless stations.
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, please double check that no indoor wireless stations or special low-power wireless
stations are operating within the interference range of this product.
