OPERATION
After you have madeconnections asnoted earlier,
operation isvery simple.
PressPOWER to turn the Tuner on. The dial scale
and meters will light up.
To Listen to FM
Set the Selector switch to FM AUTO or FM
MONO and adjust Tuning for the desired station.
Tune for a maximum reading on the TUNING
meter.
To listen to Stereo FM, the Selector switch must
be in FM AUTO position. Now, asyou tune, when
you come to astation which is broadcasting in
Stereo, thered FM STEREO LED will light up.
If you are listening to a weak stereo FM signal, the
stereo separation may be very poor, or the signal
may be noisy. In this case, the signal is just too
weak for good stereo; press the HI-BLEND
FILTER in or turn the Selector switch to FM
MONO-the signal will no longer be stereo, but it
should be lessnoisy.
If you wantmonaural reception from astereo FM
signal or for monaural FM stations, useFM MONO
position.
For automatic, locked-in fine tuning, pressAUTO-
M TUNING button in. Now, when you touch
Tuning knob, the green AUTO-M Indicator LED
will go out. Tune in astation and releaseTuning;
the Auto-Magic circuit will electronically fine-
tune the station and lock it in (no chance of drift-
ing off-station). Notice that asyou releasetuning,
the AUTO-M LED will light up.
If you want normal FM tuning, press AUTO-M
again to releasethe Auto-Magic circuitry.
Tuning Manually
If you are trying to listen to a weak station located
between two very strong stations, it may be
necessaryto tu ne manually.
With AUTO-M button out, adjust Tuning until
you find the station you want. Now fine-tune for
the highest reading of the TUNING meter.
NARROW Band/WIDTH
If you are listening to a weak FM station located
near astrong-signalstation (for example, adjacent
channels on the FM band), you maywish to push
in the NARROW Band/WIDTH button. This will
increase the Tuner's selectivity and reduce inter-
ference from the adjacent channel. For normal
signal conditions where adjacent channel inter-
ference is not a problem, leave button out:
high-frequency responseisbetter in this position.
FM 25,uS
For normal FM listening, leaveFM
25j 1S
DE-EMP
button out. If you want to record asignal being
broadcast by an FMstation usingDolby NR, press
this button in. Then, when you play backthe tape,
you must use a Dolby Decoder (that is, record
with a Dolby-type tape recorder, but with Dolby
"off") then play back with the Tape Deck's Dolby
circu itry "on". If you pressthe FM 25
j1S
DE-EMP
button inwhen listening to a Dolby FMsignal, its
sound will beexcessively "bright" (too much high-
frequency emphasis). If you have a Dolby NR
Decoder, you can connect it to your Amplifier/
Receiver's TAPE IN/TAPE OUT jacks and set
Tape Monitor switch to TAPE. Then when an FM
station is broadcasting a Dolby ·FM signal, you
will enjoy the following advantages:
Improvedsignal-to-noise ratio
Full program dynamic range, even at high fre-
quencies
Improved reception in weak-signalareas
