ZENITH RADIO CORPORATION CHICAGO, ILLINOIS 60639



NOTE: UHF information in this book applies to models equipped for VHF-UHF reception.

General Notes

1. Place receiver where no bright light will fall on the screen or in the eyes of the viewers.

2. Viewers should not be seated closer than a distance of 5 ft. from the screen for maximum comfort.

3. Place where unimpeded cabinet ventilation is allowed. If receiver is to be placed along a wall allow several inches between wall and cabinet back. This is important for proper ventilation.

WARNING, HIGH VOLTAGE

It is recommended that only your authorized Zenith television technician make repairs or adjustments inside the receiver. A severe shock can result from tampering.

POWER SUPPLY

Do not attempt to operate on DC or line supplies of other voltages or frequency ratings than those stated on the cabinet back.

CABINET STAINS

To preserve the finish on your Zenith Television cabinet, instruments or ornaments with rubber feet should not be placed on it. The chemicals in the rubber feet have a tendency to leave a stain.

PICTURE GLASS

Your Zenith is equipped with the new sealed picture glass and tube. Simply clean it from the front of the set when necessary.

Use lukewarm water and a mild soap solution. Carefully wipe dry with a clean, damp chamois cloth.



Controls

PULL-PUSH ON-OFF SWITCH—VOLUME CONTROL

To turn receiver ON, pull knob outward. To turn receiver OFF, push knob inward. Clockwise rotation of the knob increases the volume, counterclockwise rotation diminishes the volume.

Allow the receiver to warm up for about 1 minute before you wish to use it.

CHANNEL SELECTOR (VHF)

Turn knob to channel desired.

PERMA-SET TUNING CONTROL (VHF) NOTE: Your Zenith has the new Perma-set tuning control.

Each channel has been correctly set at the factory for best picture and sound.



However, should the settings become mis-adjusted, it is a simple matter to adjust them as follows:

1. Turn the VHF channel selector knob to the channel number desired.

2. Turn VHF perma-set tuning knob until there is no picture.

3. Then turn perma-set tuning knob back slowly for best picture and sound.

4. Repeat for each channel to be set.

TONE CONTROL

Your Zenith is equipped with a tone control which enables you to personally select tonal values of unmatched richness and fidelity. The high tonal register and the "bass" or low frequencies are emphasized by turning the tone control knob. Set knob to the position most pleasing to your ear.

UHF TUNING

First, turn VHF CHANNEL SELECTOR to "UHF" Position. Turn UHF Channel Tuning Control for desired UHF Channel. Then carefully turn UHF Fine Tuning knob for best picture and sound.

Disregard channel numbers 12 and 13 if they appear in the UHF indicator dial of your unit. These are VHF channels to be tuned in with the VHF selector.

PEAK PICTURE (SOME MODELS)

Set this control for best picture crispness in your location. The strength of the signal being received and your personal preference for picture detail will determine the optimum setting.

SERVICE

Your new Zenith television receiver is engineered for dependable long life service but like any mechanical or electrical instrument, it will occasionally require maintenance. For service consult your Zenith dealer or refer to the organization that installed your instrument. (See warranty.)



Picture Adjustments

BRIGHTNESS

Rotate clockwise to increase the brightness; counterclockwise reduces the brightness. It is to be used in conjunction with the contrast control since its movement will also have an effect on picture contrast.



NOTE: The brightness control setting for the picture shown in Figure 2 is set too high. Set the control below this level.

CONTRAST

Adjust the picture for best distinction between the black and white shading. Your own vision is the best judge in setting this control properly.



NOTE: The contrast control setting for the picture shown in Figure 3 is set too high. Set the control below this level.

HORIZONTAL HOLD CONTROL

If the picture appears to have a tendency to move across the screen, or if it assumes a broken streaked appearance, as indicated in Figure 4, it should be readjusted to a point where the pictures remain locked in properly on all channels.



VERTICAL HOLD CONTROL

This control is used in correcting for vertical movement, or rolling up or down. Set control to lock picture. (Fig. 5)



Interference

The most effective means of reducing interference to a minimum has been built into your Zenith Television receiver. Occasionally however, the picture may be affected by electrical interference or reflections.

AUTO IGNITION AND APPLIANCES

Automobile ignition, electrical appliances, etc., cause a speckled streaked appearing picture as shown. This condition is most noticeable in weak signal areas. (Fig. 6.)



DIATHERMY

Diathermy produces a distinctive herringbone pattern and one or two horizontal bands across the face of the picture. (Fig. 7). It can sometimes be reduced or eliminated by the insertion of a filter trap at the antenna terminals.



R.F. INTERFERENCE

Radio signals by a neighboring commercial, amateur or police station may cause interference in the form of moving ripples or diagonal streaks. Television or FM receivers operating near your receiver, can also be the reason for this reaction. (Fig. 8.)



The insertion of a filter trap at the antenna terminals of the TV receiver will sometimes eliminate or reduce this type of interference.



Antenna Connections



An outdoor type antenna is recommended for best reception. If such installation is impossible, different type indoor antenna may be used. Quality of reception also depends upon local signal conditions.

Some models are equipped with a di-pole or mono-pole antenna mounted at the cabinet back. To use this antenna, raise and extend rods. Vary the length and position of the rods or rod for best picture and sound.

Under favorable receiving conditions, satisfactory reception may be obtained with a 10 ft. length of antenna wire. (Supplied with some models). Stretch out wire for best reception.

When using a regular outside antenna, disconnect the inside antenna leads from the antenna terminal screws. Connect the antenna transmission line to both of these terminal screws.

THE PROOF OF ZENITH ANTENNA SUPERIORITY IS IN THE PICTURE.

Zenith TV antennas are designed and constructed to provide you maximum service and superior performance. Contact your Zenith dealer for the one that will provide you with the best picture quality.

DIPLEXER

(SEE PAGE 8)

When using a combination VHF-UHF antenna system with a single transmission line it is necessary to have an additional diplexer at the receiver.

Make the transmission line lengths from the diplexer to the VHF and UHF antenna post terminals on the receiver as short as possible. See your Zenith dealer for additional information.

OSCILLATOR ADJUSTMENTS (VHF)

NOTE: The VHF perma-set tuning control on the tuner is also the VHF channel oscillator adjustment. No additional oscillator adjustments are incorporated. Therefore, should re-tuning of a VHF TV channel be required, select the channel and then manually turn the tuning knob for best picture and sound. Each individual VHF channel is tuned in this manner.



Phonevision

A three-year commercial trial of Zenith's Phonevision[A] systems of over-the-air subscription television has been in progress for the Hartford, Connecticut area since June 29, 1962.

Authorized by the Federal Communications Commission, the trial has made it possible, for the first time, for about 5000 American TV homes to enjoy the convenience and economy of viewing top flight box-office entertainment and other features broadcast to their home receivers. Features at prices for the entire family no greater than a single admission at the theatre, stadium or concert hall. The Hartford test has already furnished factual information, rather than speculation, concerning this brand new television service. On the basis of this factual information, the F.C.C. has been requested to authorize nationwide operation. If the F.C.C. is persuaded by the results of the trial that subscription television is in the public interest and should be authorized nationally, then every home could have its own "television theatre" with the world's greatest and most costly entertainment offered for an admission well below the cost of witnessing these same events outside the home. With such premium-type programs added to entertainment now available from sponsored television, the home viewer would be able to obtain the ultimate of everything he wants to see on his own TV screen.

FUSE REPLACEMENT

Remove cabinet back for access to main chassis fuse if it ever becomes necessary to replace it.



INSTALLATION INSTRUCTIONS FOR S-23427 ZENITH DIPLEXER

The diplexer is designed for use with a combined VHF-UHF antenna system incorporating a single transmission line. Figures A, B, C, and D show diplexer installed on various chassis models. UHF reception should be tried with and without the inductance wire to obtain the best overall results. Disconnect leads from previous antenna system. Install diplexer assembly in manner most suitable to TV chassis model.

NOTE: Always connect the diplexer assembly with coil terminal to VHF antenna terminal.
