◎ Wireless LAN (Wi-Fi
) has the advantage that it can be freely
connected anywhere within the radio wave range, as it uses radio
waves for exchanging information. At the same time, there is a risk
that a malicious third party may obtain unauthorized access if
security settings have not been configured. You are recommended
to configure security settings before using wireless LAN at your
direction and responsibility.

)
outside is prohibited by the Radio Law.
The channels used on the product are as follows.
• W52 (5.2 GHz band/36, 40, 44, 48 ch)
• W53 (5.3 GHz band/52, 56, 60, 64 ch)

Cautions on using FM transmitter
• Use the FM transmitter function in Japan. Use overseas
may be subject to punishment by law.
• FM transmitter function uses a weak radio wave that does
not require licensing of radio stations in Japan. Therefore
depending on the receiving device or other conditions,
noise, interruption of voice sound, or distortion may occur.
• Use FM transmitter with the FM transmitter antenna
(1Seg antenna) extended.
• If obstacles exist between the FJL21 and the receiving
device or metal objects are got close to the FJL21, noise,
interruption of voice sound, or distortion may occur.
• If noise, interruption of voice sound, or distortion occurs,
try to get the FJL21 to the receiving device or to change
the direction of the antenna of the FJL21 etc.
