The frequency band used by the terminals Bluetooth/wireless LAN
function is written as follows:
2.4: This radio equipment uses the 2400 MHz band.
FH/DS/OF: Modulation scheme is the FH-SS, other system, DS-
SS, or OFDM system.
1: The expected interference distance is 10 m or shorter.
4: The expected interference distance is 40 m or shorter.
: All bandwidths between 2400 MHz and 2483.5
MHz are used, and the bandwidth used by mobile object
identification devices cannot be avoided.
Use of Bluetooth function is limited in some countries. Check the
regulations of the country/region before using it.

Cautions on using Bluetooth devices
The operating frequency band of the terminal is used by industrial,
scientific, consumer and medical equipment including microwave
ovens, premises radio stations for identifying mobile units used in
the manufacturing lines of plants (radio stations requiring a license),
specified low power radio stations (radio stations requiring no
license) and amateur radio stations (hereinafter referred to as
"another station").
- Before using this equipment, confirm that "another station" is not
being operated nearby.
- In the event of the terminal causing harmful radio wave
interference with "another station", promptly change the location
of use or stop radio wave emission by turning off the power, etc.
- If you have further questions, contact "General Inquiries" on the
last page.
Wireless LAN (WLAN) precautions
・
Wireless LAN (WLAN) exchanges information using radio
waves, and allows you to freely establish LAN connection if
you are within an area where radio waves reach. On the other
side, if you communicate without appropriate security
settings, communications may be intercepted or hacked by
malicious parties. It is recommended to configure necessary
security settings on your own judgment and responsibility.
・
Wireless LAN
Do not use wireless LAN near magnetic devices such as electrical
appliances or AV/OA devices, or in radio waves.
- Magnetism or radio waves may increase noises or disable
communications (especially when using a microwave oven).
- When used near TV, radio, etc., reception interference may occur,
or channels on the TV screen may be disturbed.
