Wireless LAN
If you use a wireless LAN, you can use a network without cable connections.
NOTE
CAUTION
Communication is performed through the wireless LAN antenna. Do not block the
antenna area with your hand or otherwise interfere with the passage of the radio
signals.
Wireless LAN Antenna
The communication speeds and distances differ depending on the devices that sup-
port the wireless LAN, the installation environment and other ambient conditions.
One characteristic of radio waves is that their transmission rate tends to drop as
the communication distance increases. It is recommended that the devices sup-
porting the wireless LAN be used in close vicinity to each other.
The rate may drop while a microwave oven is being used.
