Precautions for using the wireless LAN function (Continue)

■

Wireless LAN Router

●

Connection to all wireless LAN routers and wireless LANs in residential environments cannot be 

guaranteed.

●

Radio reception may be lost or interrupted in buildings made of concrete, steel, or metal, near 

obstacles, or near devices that use the same frequency band (2.4GHz band) (such as Bluetooth

®

devices and computer peripherals).

●

The communication standard must be one of the IEEE802.11b/g/n (2.4GHz band only).

5 GHz band communication standards are not supported.

●

Connect this product to the internet via a router.

This product cannot be directly connected to the communication lines (including public wireless 

LAN) of telecommunication carriers (mobile communication companies, 

fi

xed-line communication 

companies, Internet providers, etc.).

Radio waves and Radio Interference

Speci

fi

cation of the communication method

Wireless LAN IEEE802.11b/g/n is supported.

Frequency bands used.

 The speci

fi

cations for the radio frequency bands used by this product are as follows (These are shown 

on the nameplate)

The frequency band used (2.4GHz)
Modulation methods (DSSS and OFDM)
Radio interference distance (less than 40m)

Availability of frequency change

(All bandwidths can be used, and the bandwidth of the

mobile identi

fi

cation device can be avoided)

In the frequency band in which this product is used, industrial, scienti

fi

c, and medical equipment as well 

as premises radio stations for mobile identi

fi

cation (licensed radio stations) and speci

fi

ed low-power radio 

stations (unlicensed radio stations) used in factory production lines, etc., and amateur radio stations 

(licensed radio stations) are in operation.

1

Before using this product, make sure that there are no radio stations for mobile identi

fi

cation, 

speci

fi

ed low power radio stations, or amateur radio stations operating nearby.

2

In the unlikely event that this product causes harmful interference to a mobile identi

fi

cation radio 

station, immediately change the frequency of use, or stop emitting radio waves. Consult with 

the consultation service counter for advice on connecting to a smartphone or network to avoid 

interference, such as the installation of partitions.

3

If any other problems arise involving harmful radio interference from this product to speci

fi

ed 

low-power radio stations for mobile identi

fi

cation or amateur radio stations, please contact the 

consultation service counter for advice on connecting to a smartphone or network

.

Use of this product in the following locations may result in unstable communication:

●

Dismantling areas where magnetic 

fi

elds, static electricity, or radio waves are generated (including 

microwave ovens.)

●

Around devices that use the same frequency band (2.4GHz band) as this product (Bluetooth

®

devices, PC peripherals, etc.)

●

Places covered with metal objects that can easily re

fl

ect radio waves.

■

Security

●

When using a wireless LAN device, regardless of the encryption settings, there is a possibility that the 

device will be intercepted due to its use of radio waves.

●

Please use a wireless LAN router con

fi

gured to use WPA2 or WPA (TKIP or AES) encryption.

●

The wireless LAN function uses radio waves to exchange information between this product and a 

wireless LAN router. It has the advantage of allowing free LAN connections within the range of radio 

waves. Unauthorized persons may intercept the communication contents since the radio waves can 

reach anywhere within the range of the product, including obstacles (such as walls).

●

Do not connect to devices or networks that you are not authorized to use when setting up the wireless 

LAN function.

●

When disposing of the product or transferring it to a third party, please erase all registered information 

as described in the instruction manual included with the product.

●

If the product is transferred from a third party, please erase all registered information in the instruction 

manual supplied with the product to prevent unauthorized access by a third party.
