• FM stereo waves may produce a hiss
noise when a certain level is reached.
• The position or direction of the FM
antenna is incorrect.
• The station is too weak.
• The radio wave is distorted.
• Cars are running or airplanes are flying
near the house.
• There is a tall building or a mountain
nearby.
(The waves transmitted from the
transmission center (direct waves) and
the waved reflected by buildings or
mountains (diffraction waves) interfere
with each other causing multi pass
distortion.)
• The power cord is unplugged for a long
time.
• The sound system you are trying to
record is DTS Surround.
• No batteries are inserted in the remote
controller.
• The batteries are worn out.
• The remote controller is not pointed at the
remote sensor of the DVD Changer
Receiver.
• The remote controller is too far from the
DVD Changer Receiver.
• Any wrong MODE button is pressed.
Remedies
• Switch the frequency receiving mode to
mono.
• Adjust the position, height, and direction
of the FM antenna.
• Connect an FM outdoor antenna. Try to
use an antenna with more elements.
(For installation of the outdoor antenna,
consult your nearest dealer as it requires
special skills and experience.)
