Notes on using Bluetooth function
z
The handset supports the security function that meets the
Bluetooth specification for security during communication
using Bluetooth functions. However, the security may not
be sufficient depending on the configuration etc. Take care
of the security while making communication using
Bluetooth function.

①
2.4: This radio equipment uses the 2,400 MHz band.
②
FH: The modulation system is the FH-SS system.

Cautions on using Bluetooth devices
Bluetooth operates at radio frequencies assigned to the in-house
radio stations for a mobile object identifier that have to be
licensed and are used in production lines of a factory, specific
unlicensed low power radio stations, and amateur radio stations
(hereafter, referred to as “another radio station”) in addition to
industrial, scientific and medical devices or home electric
appliances such as microwave ovens.
1. Before using the handset, make sure that “another radio
station” is not operating nearby.
2. If radio interference between the handset and “another
radio station” occurs, avoid interference by moving
immediately to another place or “turning off the power”.
3. Contact the number listed in “General Inquiries” on the
last page for further details.
Notes about wireless LAN (WLAN)
z
Wireless LAN (WLAN) uses radio waves to communicate
information. Therefore, it has an advantage of freely
connecting to the LAN within the service area. On the other
hand, if security setting is not set, it is possible for a
malicious third party to intercept the communication
contents or hack. It is recommended to set security setting
at your own risk and judgement.
z
Wireless LAN
Do not use wireless LAN near magnetic devices such as electric
appliances or AV/OA devices or in radio waves.
y
Magnetism or radio waves may increase noises or disable
communications (especially when using a microwave oven).
