below.
2.4FH/XX1
Frequency band is 2.4 GHz. FH-SS or other-method modulation,
with a maximum interference range of about 10 m.

When Using Bluetooth
®
・Handset Bluetooth
®
function is certified as conforming
with Japanese domestic standards, FCC standards, and EC
directives. Use of handset Bluetooth
®
function is restricted
in some countries/regions. Be sure to check laws and other
conditions of the country/region.
・2.4 GHz band used by Bluetooth
®
devices is shared by many
other different devices. As a result, Bluetooth
®
devices
use technology to minimize interference from devices using
the same frequency band, however, communication speed
and distance may be reduced or communication may be
interrupted in some instances.
・Communication speed and distance depends on distance
between devices, obstacles, and the Bluetooth
®
devices.
Usage Precautions
Handset Bluetooth
®
function uses 2.4 GHz frequency band.
This is the same frequency band used by household appliances
such as microwave ovens and industrial, scientific, and
medical equipment, other same-type radio stations, (licensed)
premises radio stations used to identify mobile units used in
manufacturing lines, (unlicensed) specified low-power radio
stations, and (licensed) amateur radio stations (below, "other
radio stations").
1. Before using handset, check that other radio stations are
not in use nearby.
2. If interference should occur with other radio stations,
change handset location, or stop operation of the device (stop
emission of radio waves).
