 Check the network connection
(page 22) and the network settings

the possible communication distance
may be shortened. Move the system

band, such as a microwave,
BLUETOOTH, or digital cordless
device, may interrupt
communication. Move the unit away
from such devices, or turn off such
devices.
 The wireless LAN connection may be
unstable depending on the usage
environment, especially while using
the BLUETOOTH function of the
