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 technicianmake repairs or adjustments inside the receiver. A severe shock canresult from tampering. POWER SUPPLY Do not attempt to operate on DC or line supplies of other voltages orfrequency ratings than those stated on the cabinet back. CABINET STAINS To preserve the finish on your Zenith Television cabinet, instruments orornaments with rubber feet should not be placed on it.

Thestrength of the signal being received and your personal preference forpicture detail will determine the optimum setting. SERVICE Your new Zenith television receiver is engineered for dependable longlife service but like any mechanical or electrical instrument, it willoccasionally require maintenance. For service consult your Zenith dealeror refer to the organization that installed your instrument. (Seewarranty. ) Picture Adjustments BRIGHTNESS Rotate clockwise to increase the brightness; counterclockwise reducesthe brightness. It is to be used in conjunction with the contrastcontrol since its movement will also have an effect on picture contrast. [Illustration: FIG. 2] =NOTE:= The brightness control setting for the picture shown in Figure 2is set too high. Set the control below this level. CONTRAST Adjust the picture for best distinction between the black and whiteshading. Your own vision is the best judge in setting this controlproperly. [Illustration: FIG. 3] =NOTE:= The contrast control setting for the picture shown in Figure 3 isset too high. Set the control below this level. HORIZONTAL HOLD CONTROL If the picture appears to have a tendency to move across the screen, orif it assumes a broken streaked appearance, as indicated in Figure 4, itshould be readjusted to a point where the pictures remain locked inproperly on all channels. [Illustration: FIG. 4] VERTICAL HOLD CONTROL This control is used in correcting for vertical movement, or rolling upor down. Set control to lock picture. (Fig. 5) [Illustration: FIG. 5] Interference The most effective means of reducing interference to a minimum has beenbuilt into your Zenith Television receiver. Occasionally however, thepicture may be affected by electrical interference or reflections. AUTO IGNITION AND APPLIANCES Automobile ignition, electrical appliances, etc. , cause a speckledstreaked appearing picture as shown. This condition is most noticeablein weak signal areas. (Fig. 6. ) [Illustration: FIG. 6] DIATHERMY Diathermy produces a distinctive herringbone pattern and one or twohorizontal bands across the face of the picture. (Fig. 7). It cansometimes be reduced or eliminated by the insertion of a filter trap atthe antenna terminals. [Illustration: FIG. 7] R. F. INTERFERENCE Radio signals by a neighboring commercial, amateur or police station maycause interference in the form of moving ripples or diagonal streaks. Television or FM receivers operating near your receiver, can also be thereason for this reaction. (Fig. 8. ) [Illustration: FIG. 8] The insertion of a filter trap at the antenna terminals of the TVreceiver will sometimes eliminate or reduce this type of interference. Antenna Connections [Illustration: FIG. 9--ANTENNA CONNECTIONS AT CABINET BACK FIGURE 9. NOTES: 1. FOR POSSIBLE BETTER PERFORMANCECONNECT ADDITIONAL WIRE TO REMAININGANTENNA TERMINAL 2. TACK OR TWIST END OF WIRE TO CONVENIENTPOINT UP AND AWAY FROMTV CHASSIS (VARY POSITION FOR BESTRECEPTION. ) ADDITIONAL 10 FT LENGTH WIREAPPROX. TV RECEIVER] An outdoor type antenna is recommended for best reception. If suchinstallation 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 atthe cabinet back. To use this antenna, raise and extend rods. Vary thelength and position of the rods or rod for best picture and sound. Under favorable receiving conditions, satisfactory reception may beobtained with a 10 ft. Length of antenna wire. (Supplied with somemodels). Stretch out wire for best reception. When using a regular outside antenna, disconnect the inside antennaleads from the antenna terminal screws. Connect the antenna transmissionline 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 maximumservice and superior performance. Contact your Zenith dealer for the onethat will provide you with the best picture quality. DIPLEXER (SEE PAGE 8) When using a combination VHF-UHF antenna system with a singletransmission line it is necessary to have an additional diplexer at thereceiver. Make the transmission line lengths from the diplexer to the VHF and UHFantenna post terminals on the receiver as short as possible. See yourZenith dealer for additional information. OSCILLATOR ADJUSTMENTS (VHF) =NOTE:= _The VHF perma-set tuning control on the tuner is also the VHFchannel oscillator adjustment. _ No additional oscillator adjustments areincorporated. Therefore, should re-tuning of a VHF TV channel berequired, select the channel and then manually turn the tuning knob forbest picture and sound. Each individual VHF channel is tuned in thismanner. Phonevision A three-year commercial trial of Zenith's Phonevision[A] systems ofover-the-air subscription television has been in progress for theHartford, Connecticut area since June 29, 1962. Authorized by the Federal Communications Commission, the trial has madeit possible, for the first time, for about 5000 American TV homes toenjoy the convenience and economy of viewing top flight box-officeentertainment and other features broadcast to their home receivers. Features at prices for the entire family no greater than a singleadmission at the theatre, stadium or concert hall. The Hartford test hasalready furnished factual information, rather than speculation, concerning this brand new television service. On the basis of thisfactual information, the F. C. C. Has been requested to authorizenationwide operation. If the F. C. C. Is persuaded by the results of thetrial that subscription television is in the public interest and shouldbe authorized nationally, then every home could have its own "televisiontheatre" with the world's greatest and most costly entertainment offeredfor an admission well below the cost of witnessing these same eventsoutside the home. With such premium-type programs added to entertainmentnow available from sponsored television, the home viewer would be ableto obtain the ultimate of everything he wants to see on his own TVscreen.
