Two extra conlrols provide the Signal Seeking fealures;
• Sensitivity Selector-located just behind the manual tuning knob.
Turning this control clockwise increases the number of stations
available for automatic tuning. With the Sensitivity Selector
in the extreme clockwise position the Automatic Tuning Bar will
tune in all listenable stations, while in the extreme counterclock-
wise position only the most powerful available stations will be
tuned in.
• Automatic Tuning Bar-Push this bar (located above the radio diaO
to reject the station to which you are listening and move to the
right to the next station in the range selected by the Sensitivity
Selector. When the extreme right of the dial is reached, the
Tuning Bar will automatically return to the station at the extreme
left and begin all over again, automatically selecting the stations
offering the best reception.
HEATER
The Chevrolet Deluxe Heater provides year round comfort regardless
of the weather. The easily operated controls are located within reach
of both driver and front seat passengers.
TO HEAT
• Set HEAT Lever for desired air temperature.
Full "down" position of this lever will
provide the maximum possible air
temperature.
• Set
right
AIR Lever to INSIDE (full "up" position) if recircu-
lated air from inside car is desired, or to OUTSIDE (full
"down" position) to direct outside air through the heater. The
INSIDE position is useful when outside air is contaminated by
smoke or fumes.
• Move BLOWER switch to provide the desired blower speed.
(Often, with the right AIR lever in OUTSIDE position, the blower
switch need not be used because the forward movement
of
the car
will force a sufficient flow of air through the heater.)
TO DEFROST
• Set heater panel controls as for heating.
• Set DEFR Lever to divert desired amount of
air flow from the heater ducts to the de-
froster ducts. (If lever is set all the way down,
the entire air flow will go to the defrosters).
SUMMER VENTILATION
• Set the HEAT and DEFR Levers to fu ll
"UP" position.
• Set left VENT Lever to full "DOWN" Set
right Air Lever to AIR (center) position.
