Mazda 2: Reference [Radio]
1. Multipath Noise
- Signals from an FM transmitter are a high frequency and similar to beams
of light
because they do not bend around corners, but they do reflect. Since FM
signals can be
reflected by obstructions, it is possible to receive both the direct signal
and the
reflected signal at the same time. This causes a slight delay in reception
and may be
heard as a broken sound or a distortion.

2. Flutter/Skip Noise

3. Stereo and Monaural Receptions
- As signals become weak, noise may appear more in stereo reception.
Compared to
stereo reception, noise in monaural reception is relatively less striking.
Measures in Audio System
Separation control
- Utilizing the characteristic of monaural reception that noise is
relatively less striking
than stereo reception, the audio system automatically changes the reception
from
stereo to monaural and lessens annoying noise when signals become weak or a
multipath phenomenon occurs.
High tone control
- When signals become weak or a multipath phenomenon occurs, the audio
system
restrains volume level in high frequency band and lessens annoying noise.

Remarks
- Signals tend to reach longer distances at night. It is conspicuous in AM
signals, several
audio functions may stop due to foreign broadcasting station or noise.
Though the
audio system restrains sensitivity of SEEK and SCAN functions at night, the
audio
system may select other than desired broadcasting station when signals are
considerably strong. This function is linked to the parking light. When the
parking light
or the headlight is turned on, SEEK and SCAN may not function for weak
signals.

NOTE:
- Normal operation of the security light is as follows. The light starts
flashing every 2 s when
the ignition is switched from ON to ACC and the immobilizer system is armed.
The light
stops flashing when the ignition is switched to ON with the correct ignition
key. At this time,
the immobilizer system is disarmed and the security light illuminates for
about 3 s and then
goes out.
