TUNING
This control changes the dial setting and tunes
in the desired station.
STEREO INDICATOR LAMP
This indicator will light with a steady glow
when
an FM station that is broadcasting a
stereo sigial is tuned in, if the SOURCE switch
is in the (§) FM, @ FM, @ AUX, or @ AUX
positions. Note that in some cases it may flicker
on and off due to the noise between stations.
It may also light for short periods of time on
stations that use a "Commercial Killer" signal.
This signal eliminates the commercials from
the music that these stations sell to business
establishments.
PHASE CONTROL AND SWITCH
This control and switch is only used when tuned
to a station that is broadcasting an FM stereo
~nal. The SOURCE switch must be set at the
® FM position. When you tune to different
stations, the Phase control will produce maxi-
mum stereo separation by correcting any trans-
mitted phase errors.
To set the PHASE control, pull the knob out to
activate the switch, and adjust the control in
either direction for the loudest output signal.
Then push the knob back in without disturbing
the control setting.
HOW TO GET THE MOST OUT OF YOUR
RECEIVER
Use the following procedure to get the greatest
possible enjoyment out of this high quality Stereo
Receiver. The Receiver should be connected to
good quality speakers. The speakers should be
placed far enough apart to provide good stereo
separation; approximately 4 to 8 feet.
Set the SOURCE switch to the @ FM position,
Tune in a station that is broadcasting stereo,
as indicated by a steady glow of the stereo
indicator lamp.
Pull out the PHASE control knob and adjust this
control in either direction for the loudest output,
Then push the knob back in without disturbing
the setting of this control.
NOTE: The Phase control adjusts the phase of
the 38 kc reinserted carrier. It may be neces-
sary to readjust this control when tuning to
another station, to correct transmitted phase
errors and obtain maximum stereo separation,
Set the SOURCE switch to the @ FM position,
Adjust the volume controls to produce an equal
sound level from each speaker at the desired
listening level.
To receive monophonic FM programs, always
set the SOURCE switch to the @ FM posi-
tion. This will produce the best signal-to.
noise ratio.
