Tuning on FM
Select FM reception by depressing the FM button.
The red light over the button will light telling you that
the receiver is in the FM mode.
Use the large knob on the right side of the scale to
tune in the required station.
NOTE!
Make sure that the PREAMP REC
button is released.
Correct tuning is important, particularly for stereo, if
distortion is to be avoided. This receiver is there-fore
equipped with two tuning meters, one indicating signal
strength (SIGNAL) and the other indicating midscale
for exact tuning (TUNING). First adjust the tuning
knob for maximum deflection on the SIGNAL meter
and then make a final fine adjustment to obtain
midscale deflection on the TUNING meter.
The frequency calibration of the scale is accurate to
within ± 200 kHz. So do not be confused if a station
transmitting on, for instance, 103.9 MHz tunes in at
104.1 MHz on the scale. This is still within the
tolerance. The scale is simply a guide and what really
matters is that you use the two tuning meters correctly.
Muting
The high amplification necessary to obtain good
sensitivity and limiting in high class tuners, makes
tuning noisy. To avoid this, a muting circuit blocks the
receiver automatically when no signal is received or if
the signal is to weak to give satisfactory noise
suppression. To receive a station that is not strong
enough to cancel the blocking effect of the muting
circuit, the circuit can be switched off.
The muting function is activated by depressing the FM
muting knob on the extreme right side of the front
panel. Another push on the button will release it and
cancel the muting.
