OPERATING INSTRUCTIONS
This radio incorporates the new Hudson Automatic Touch Tuning. The purpose and position of each control is shown in (Fig. 1).
To Turn Radio On
Press push button on right side below ON-OFF indicator window and allow receiver to reach operating temperature.
(Approximately 20 seconds.)
Manual Tuning
1. Press the automatic tuning push button on the left side beneath automatic indicator window several times or until the letter "M"
appears in the automatic indicator window.
2. Pull manual tuning (right hand) control knob outward and turn to tune in desired stations. Tune to exact frequency for the best
tone quality.
Volume
Adjust left hand control knob for desired volume.
Tone Control
The tone control is located directly behind the volume control knob (Fig. 1). Rotating this control to the right or left will change
the tone of the receiver. The treble position is useful in overcoming wind, noise, etc. when driving, while the bass position brings
out the full mellow tones of musical programs. With the tone control set midway, the full tonal range is obtained. Turning to the
right will emphasize the high notes, while turning to left will emphasize the bass notes.

Automatic Tuning
There are five automatic tuning positions which may be adjusted to five desired stations. If
these positions have not been previously adjusted proceed as follows:
1. Press the automatic tuning push button (on the left side) until Number 1 appears in the
automatic indicator window.
2. Pull the manual tuning knob OUTWARD to engage the automatic mechanism.
3. Select the station desired and tune to its frequency by turning the tuning knob. Tune very
carefully for clearest reception.

cally return to the "IN" position when the automatic tuning push button or the foot switch is
operated.
4. Press the automatic tuning push button, pull manual tuning knob outward, and tune in
station desired for No. 2 position. Use the same procedure for positions No. 3, 4 and 5.

without taking the hands off the steering wheel or the eyes from the road. Its function is
identical to that of the automatic tuning push button. The foot control requires no set up or
other adjustment. Press the foot control button all the way down to change stations. Press
