Auto Tuning
If signals are strong and there is no interference, quick
automatic search tuning is possible.
1.
Select the tuner source with the INPUT SELECTOR.
2.
Select the reception band with FM/AM button.
3.
Press the TUNII\JG MODE button so that the AUTO
TUNING indicator lights up.
4.
Select the IF mode with the IF MODE button.
5.
Use the TUNING button to tune.
The tuning will start automatically and stop at
broadcast station frequency with a sufficient signal
strength.
6.
If the station where tuning stops is not the one you
want, press the TUNING button once again.
7.
Adjust the VOLUME control, TONE controls, etc.
•
When an FM stereo broadcast with a sufficient
signal strength is received, the STEREO indicator
lights.
•
When the received station is locked with the
computer servo lock system, the CSL indicator
lights.
Technical notes o:n the Computer Servo Lock
(CSL) system
The new YAMAHA Computer Servo Lock Tuning
system eliminates many conventional tuning problems
by effectively providing two different tuning modes,
each optimized for different types of reception
conditions, and both controlled by a sophisticated
microprocessor. The microprocessor discriminates
between different reception conditions and selects the
appropriate tuning mode according to the quality of
the received signal. If the station has a strong, high
quality signal, an infinite resolution FM stereo tuning
circuit is used for maximum audio quality. With a
weak, poor quality signal, the PLL tuning mode locks
on to the broadcast frequency to ensure the best
possible reception.
Manual Tuning
Auto tuning may be impossible if the station signal is
weak. If so, use manual tuning.
1.
Select the tuner source with the INPUT SELECTOR.
2.
Select the reception band with FM/AM button.
3.
Press the TUNING MODE button so that the AUTO
TUNING indicator goes off.
4
Select the IF mode with the IF MODE button.
5.
Use the TUNING button to tune.
The frequency will change rapidly if the TUNING
button is kept pressed. Release if slightly before
reaching the desired frequency, and then press it
intermittently until the desired frequency is reached.
Use the FINE TUNING button to tune in the station
precisely.
•
Fine Tuning
Rapid tuning is usually possible with the Auto. or
Manual Tuning method, but more stabilized reception
is possible with Fine tuning in the follows situations.
*
To receive a weak or very badly fading broadcast
signal from among many signals
*
To receive a weak or medium-strength signal which
is near a strong signal
*
If beat noise is received
In these instances, Manual Tuning and then Fine
Tuning can be used to reduce noise and distortion.
Set the TUNING MODE button to MAN'L MONO, and
then press the FINE TUNING button, so that the FINE
TUNING indicator lights.
The best reception can be easily obtained by using
the SIGNAL QUALITY indicators during fine tuning.
Preset Tuning
The preset station button can be used to select, at a
single touch, any desired station which has been
preset.
1.
Tune to the desired station using auto or manual
tuning mode.
2.
Select the range of the preset station button with
the P1-P8/P9-P16 button.
3.
Press the MEMORY button and then while the
MEMORY indicator is flickering, press the desired
preset station button.
Note
If tuning is done in the manual mode and then
MEMORY button is pressed, the preset tuning will
be in Mono. Therefore prior to pressing MEMORY
button, the tuning should be set to AUTO.
4.
To receive the preset station, select the range of
the preset station with the P1-P8/P9-P16 button and
press the desired preset station button.
•
Follow the same procedure for other preset station
buttons.
e
The new setting will be programmed in place of the
former one.
e
The settings of the IF MODE button, TUNING
MODE button and FINE TUNING button are also
preset.
Memory back-up
The memory back-up circuit will prevent the
programmed information from being lost even though
the power is switched OFF for timer use or other
temporary power failure. If, however, the unit is not
used for a long time, the memory may be erased. If
so, it can be re-programmed by simply following the
original procedure.
