Radio operation
Reception
FM reception offers the advantages of low
noise interference, minimal distortion,
wide dynamic range, extended frequency
response, and is usually broadcast in
stereo. FM frequency waves are however
relatively short and travel in a straight
line and can therefore be impeded by
obstructions, which may adversely affect
reception in certain parts of the country.
This is a condition known as Multipath
Interference.
Whilst FM reception generally provides
better quality sound, AM reception may
prove superior in remote areas not
covered by the shorter range
FM transmitters.
When experiencing poor FM reception,
background noise can be reduced by
pressing the MODE button, selecting
TREBLE and reducing the treble setting.
On/Off and volume control
Press the control knob to switch the radio
on, press again to switch off. Turn the
control knob clockwise to increase or
counter-clockwise to decrease volume.
Any volume setting made whilst in audio,
phone, or voice activation mode, will be
memorised for that system.
Automatic volume control (AVC)
This maintains radio volume at a level
sufficient to overcome road noise as
vehicle speed increases or decreases.
To activate AVC, press and hold the
volume control knob until AVC is
displayed. To de-activate AVC,
momentarily press the volume control
knob again. The level of AVC control can
be adjusted by turning the volume
control knob whilst in AVC ON mode.
When AVC is ON, manual adjustment of
volume will override the AVC setting.
MODE button
The MODE button functions at two levels
and is primarily used to adjust sound
quality to personal preference.
In addition, it is used to adjust Voice
Activation volume, select Voice
Activation Training and to set the audio
display clock.
