Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from the
transmitter. Reception in such fringe areas
is characterized by sound breakup.
Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are extremely
strong, so the result is noise and sound
breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of 2
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.
Station 1
88.1 MHz
5-88
Station 2
88.3 MHz
▼ Operating Tips for MP3
MP3 stands for MPEG Audio Layer 3,
which is standardized voice compression
established by the ISO
(MPEG).
Use of MP3 allows for audio data to be
compressed to approximately a tenth of
the source data size.
This unit plays files with the extension
(.mp3) as MP3 files.

CAUTION
Do not use an audio file extension on files
other than audio files. In addition, do not
change the audio file extension. Otherwise,
the unit will not recognize the file correctly
resulting in noise or a malfunction.
