Problem Cause Solution
The Preset Tuning function
(page 22) does not work. The preset (memory) may have been
erased. Preset radio stations again.
The preset station settings
have been cleared. The power to this unit may be lost
more than a week. Make sure the power cable is plugged
into outlet firmly, then preset the
stations again.
Problem Cause Solution
Too much noise is
generated during stereo
broadcast. The FM antenna may be connected
improperly. Make sure the FM antenna is connected
properly.
The radio station you selected may
be far away from your area or radio
wave reception is weak in your area. Try Manual Tuning to increase the
signal quality or use a
multi-channel outdoor antenna.
Even with an outdoor
antenna, radio wave
reception is weak (audio is
distorted). Multipath reflection or other radio
interferences may occur. Change the antenna’s height, direction,
or placement.
The Auto Tuning function
(page 27) does not work. The radio station you selected may
be far away from your area or radio
wave reception is weak in your area. Try Manual Tuning to increase the
signal quality or use a multi-channel
outdoor antenna.
Problem Cause Solution
Too much noise is
generated. The noises may be generated from
atmospheric electricity, lightening,
fluorescent lights, motors, or
thermostat electric devices. Connect an outdoor antenna and
establish better grounding to decrease
noises. However, it is difficult to
eliminate these types of noises.
If too much noise is generated
especially in the evening, this unit
may be placed close to a TV. Place this unit further away from a TV.
The Auto Tuning function
(page 27) does not work. The AM loop antenna may be
connected improperly. Make sure the AM loop antenna is
connected properly.
The radio station you selected may
be far away from your area or radio
wave reception is weak in your area. Try Manual Tuning to increase the
signal quality.
Problem Cause Solution
Cannot tune in to any DAB
stations. There is no DAB coverage in your area
The service reception is
weak. The positioning of the indoor DAB
antenna and/or the unit isn’t optimal for
DAB reception. Use “Manual tune” (page 29) to locate the
best DAB antenna and unit positioning for
optimal DAB reception.
