Frequency Band

This radio station utilizes 2.4 GHz band with 
FHSS modulation. Maximum transmission 
radius is 10 meters (32 feet). It is not possible 
for the radio station to avoid using the 
frequency band of the mobile unit 
identification apparatus.

Wireless LAN (hereafter "Wi-Fi") uses radio 
waves to enable communication between 
compatible devices, thus allowing connection 
to a local area network from anywhere within 
the range. However, there is a risk of data 
interception unless security is established. It is 
advisable for the user to configure security 
settings on their own responsibility before 
using Wi-Fi.

.

Do not use Wi-Fi near electrical appliances, 
audiovisual equipment or office automation 
equipment; may affect Wi-Fi transmission 
speed, availability, clarity, etc. (There is a 
possibility of interference especially when a 
microwave oven is in use.)

.

The target access point may not be detected 
correctly if there are multiple access points 
nearby.
