By sequentially pressing the AM FM button, two FM bands (FM1 & FM2) and one AM band
can be selected. The chosen band and the frequencies stored in the Memory Presets will
be confirmed on the display.

Manual Tuning

Pressing the JOYSTICK up will increase the tuning frequency and pressing down will
decrease the tuning frequency.
The radio will tune in steps of 9 KHz for AM and 0.1 MHz for FM.
If the button is kept depressed, the frequency will increase or decrease at a fast rate until
the button is released.

Seek Tuning

This function seeks radio stations automatically.
Pressing the right hand side of the JOYSTICK will automatically select the next higher
frequency radio station, and pressing the left hand side of the JOYSTICK will automatically
select the next lower frequency radio station.
As the radio can seek weak and noisy distant radio stations, it is recommended to switch
the multi function button 8 below "LOC" to the Local On position. This limits the seek tuning
to stronger local radio stations only. "LOC" will be indicated on the display. For more
information on LOCAL refer to "Local / Distance Selector" section of handbook.

Radio Memory Presets

Briefly pressing one of the multi function buttons 1 to 6 (presets), will recall the radio station
frequency which has been stored into that particular preset. The corresponding button
number will be highlighted on the display.
18 radio station frequencies (6 for AM, 6 for FM1 and 6 for FM2) can be stored into the 6
preset buttons.
PLEASE NOTE: IF the ASM function is initiated, the previously stored frequencies will be
replaced. Refer to "Automatic Radio Station Memory" section of this manual

How to store radio stations into presets

Select the desired waveband, AM, FM1 or FM2 using the AM FM Waveband selector button.
Tune in the desired radio station using the JOYSTICK.
Press and hold any one of the multi function buttons 1 - 6. After 2 seconds the audio will
briefly mute, indicating that the chosen radio station is stored into the preset.
The number of the corresponding button and the selected frequency will be shown on the
display.
Repeat the same procedure for the other five preset buttons. Each of the six presets allows
the storage of a radio station in AM, FM1 & FM2.
To override a previously stored radio station, repeat the above procedure.

Automatic Station Memory

This feature, when activated, will search for the strongest radio stations. It is of great
benefit when away from the home location, as the local radio stations can be stored without
knowing their frequency.

To activate the ASM system

Select the desired waveband, "FM1, FM2 or AM" using the AM FM button.
Briefly press the ASM button, "ASM" will be shown on the display, indicating that it is in the
process of finding and storing radio stations.
When storing is complete, the six strongest radio stations will automatically be stored in
frequency order and the radio station which is memorised in preset No. 6 will play.
To listen to the stored radio stations, press the multi function button corresponding to the
displayed frequency.

PLEASE NOTE:

Any radio station which is weaker than the ASM threshold level, will not be stored.
If less than six radio stations of sufficient signal strength are received in the selected band,
the ASM system will search twice and then store the received stations in frequency order.
To override an ASM stored frequency, follow "How to store radio stations into presets"
section of handbook.

Local / Distance Selector

The LOCAL switch adjusts the radio's seek sensitivity in both wavebands. This will cause
the seek tuning to stop only on local and strong radio stations with good reception and
clear sound quality.
To activate this function, press the multi function button 8 (below "LOC" on display). "LOC"
will be shown on the display when active, "DX" will be shown when Local is turned off.
To be able to seek weak and distant radio stations, switch LOCAL off.
The LOCAL setting has no effect during the "ASM" Auto Storing Process.

FM "STEREO" Indicator

"STEREO" will illuminate if a stereo radio station with sufficient strength is received in the
FM band.
If the stereo signal becomes weak, the radio will automatically and gradually switch to
mono, but "STEREO" may still be shown on the display.

Antenna information

For best radio reception it is recommended to have the antenna fully extended, however,
when in areas with low obstacles, tree branches etc., lowering the antenna will reduce the
chance of the antenna mast being bent or damaged.
The antenna should be periodically cleaned with a soft cloth, water and a mild detergent.
This not only helps the antenna to retract but also aids radio reception.
If the antenna becomes bent or is broken, it is suggested to have a replacement mast fitted
by your Local Dealer.

Due to varying reception locations, car radios have performance limitations that may on
occasions create the impression that your radio is malfunctioning. To assist you in
understanding what can be expected from your new radio, we have set out below how
reception may vary from time to time and under certain conditions.

AM and FM

There are two main types of radio broadcasts. AM or Amplitude Modulation in which the
amplitude of the signal is varied to produce the sound and FM or Frequency Modulation in
which the frequency is varied to produce the sound.

RANGE

AM broadcasts tend to follow the earth's curvature and also reflect from the upper
atmosphere, which enables long range reception, especially after sunset.
FM transmissions are basically line-of-sight (similar to TV signals) and are reflected by
buildings, mountains etc., but not by the upper atmosphere.

INTERFERENCE

Interference is caused by either natural or man made electrical disturbances. This can
affect the amplitude of the signal being received. AM signals are more prone to this type
of interference than FM signals. This type of interference has little or no effect on the
frequency of the received signal, thus AM is susceptible to interference from power lines,
fluorescent lighting, neon signs, traffic light control circuits, overhead tram wires and
electrical storms. With FM reception, these amplitude variations are filtered out, leaving a
relatively clear signal, (refer to "Peculiarities of FM Mobile Reception") making this one of
the major advantages of FM broadcasts.

PECULIARITIES of FM MOBILE RECEPTION

A mobile FM receiver cannot be expected to continuously provide the quality of FM
reception you may experience on your home receiver. Contrary to popular opinion, FM
broadcasts are not static free, and although your new radio has a built-in electronic
interference absorption circuit, some static will be evident from time to time, especially in
areas without a direct line of sight to the transmitter.

There are two phenomena peculiar to VHF mobile reception.

FLUTTER As VHF signals reflect off solid objects, it is possible to pass through areas
of "Shadow" caused by tall buildings and/or hilly terrain, which effectively block out the
signal. As the vehicle passes in and out of shadow areas, the level of signal will vary at a
rapid rate, creating a flutter type of interference to the signal.

DISTORTION (MULTIPATH) Distortion may occur when the direct signal from the
transmitter and a reflected signal reach the antenna at the same time and either cancel or
aid each other, like ghosting on a TV. This results in intermittent distortion of the signal
whilst moving or constant distortion when stationary, such as at a traffic light or when
parked. Should this distortion occur while stationary, moving the vehicle approximately one
or two meters would on most occasions correct the problem.Circuitry has also been
included in this radio to reduce this type of distortion.
