TRANS-OCEANIC

PORTABLE

There Is aWorld of Entertainment and Pleasure

In Your New Zenith Portable

Your Zenith Super Trans-Oceanic portable will operate on battery or

110 Volt AC-DC current. It uses aselenium rectifier and is a5tube

superheterodyne radio, covering the standard broadcast, foreign domes-

tic shortwave bands, and has continuous short-wave coverage from 2to

8megacycles (38 to 150 meters) .It has seven tuned circuits, and a3sec-

tion tuning condenser with atuned radio frequency stage insuring maxi-

mum sensitivity and selectivity. Freedom from blasting on powerful

stations is assured by anew automatic volume control circuit which

controls 3tubes on the broadcast band, ADeluxe Alnico 5, rubber

mounted, permanent magnet, speaker in conjunction with an improved

audio system provides finer tone than ever before.

The four button "RADIORGAN'' tone control permits selection

of 16 different tone combinations. The built in removable WAVE-

MAGNET provides reception in trains, planes, automobiles, boats,

and steel constructed buildings. This standard Wavemagnet is located

on the inside of the front cover and aspecial extension cable is provided

for its use on windows of automobiles, planes, trains, etc. To bring

in shortwave stations with greatly added volume turning the knob on

the top right hand corner of the cabinet allows aWAVEROD Antenna

to snap up, which, when fully extended, provides increased pick up for

shortwave reception.

Two terminals have been provided at the left rear of the chassis

marked "A" and for external antenna and ground connections.

These are for use in areas of extremely low signal strength. By merely

connecting an external antenna and ground to these terminals, signals

previously impossible to obtain are in many cases received with the

volume and clarity of local broadcasts. This external antenna and ground

is ay(omatically connected to the proper standard or shortwave circuit

when the operator presses the band selector buttons.

The band selector buttons on the front panel provide an easy

means of selecting the standard broadcast (BC) or the shortwave band

most suitable to the time of day. Each shortwave band is electrically

SPREAD, which means that stations are separated from each other to a

degree permitting great ease of tuning. Acalibrated second scale has

been incorporated in the top edge of the dial face. It permits short-

wave stations to be accurately logged and easily relocated.

All parts are fully treated against moisture, temperature, and

other climatic conditions. Variations in the performance of the receiver

because of seasonal or geographic changes are held to a minimum,

and the receiver will operate at its maximum efficiency throughout

the world Power consumption on the electric light line is 10 watts.

When the receiver is to be used in areas outside of continental

U. S. A. where 110 volts AC/DC is usually not available, ballast adaptor

No. S-15715 must be used. This ballast adaptor reduces 220 volts AC or

220 volts DC to 110 volts AC or 110 volts DC necessary for proper

operation of the receiver.

When not in use, always make certain that power is off by turning

the left control knob fully counter clockwise, until aclick is heard.

C. Proceed as instructed under paragraphs 10, 11, 12, and 13.

D. If used an average of 3to 4hours aday—30 hours aweek, the

battery will give approximately 150 hours of service.

3. LIGHT SOCKET OPERATION

(110-1 25 Volts DC or AC —25 to 60 cycle operation.)

A. Remove the line cord plug from CHANGE OVER socket. Removal

of this plug automatically trips the Battery Saver Switch and pre-

vents battery drain while operating off light socket operation.

B. Plug the line cord into any convenient light socket. After the

receiver is in operation try reversing the plug for minimum hum

or noise when operating on alternating current.

C. On direct current reverse the plug if the set does not operate

after having been turned ON. On DIRECT CURRENT the set

will operate ONLY with the plug in one position.

Supply Voltage Switch

This receiver is equipped with asupply voltage switch, which is at

the right rear corner of the chassis.

if)

Figure 3.

This supply voltage switch is preset by the factory at 117 volts.

If you are in an area where the supply voltage is lower than 110

volts; loosen the holding screw and slide the switch to expose the

105 volt stamping, refasten holding screw.

WARNING —Do not move line voltage switch from 117

volt position unless you are certain the supply voltage is below

110 volts. Operating the receiver under high supply voltage condi-

tions with the switch in 105 volt position can burn out the tubes

or materially shorten their life.

It is possible that the supply voltage can change throughout

the day since more electricity is usually being used during the

early evening hours when the demand is greatest. If the supply

voltage switch has been set in 105 volt position for the evening

hours of low voltage, the supply voltage may exceed 110 volts dur-

ing the hours of small demand. If this situation occurs, the supply

voltage switch must then be moved to 117 volt position.

220-240 Volts DC or AC —25 to 60 cycle operation.

E. If the receiver is to be used in locations where acurrent supply of

220-240 Volts AC or DC is available, ballast adaptor S15715

should be used. This ballast adaptor assembly can be obtained from

your local Zenith distributor and need only be plugged into the

ballast tube socket. (See Figure 4.)

Figure 4.—Ballast Adaptor Inserted in Socket.

1. Loosen the screw holding the switch positioning plate.

2. Move the switch on the ballast tube to either 110 volts AC-DC,

220 volts DC or 220 volts AC position to conform to the type

current on which the set is to be operated. (See Figure 5.)

Figure 5.—Ballast Tube Switch Positions.

(See Figure 6.) Study the dial carefully. The broadcast band is cali-

brated in kilocycles with the zeros deleted for convenience. This is

the white bottom scale indicated by the lower half of the pointer. The

shortwave bands are spread and calibrated in megacycles, four are

located on the upper half of the dial scale and two in the lower half.

Read with the upper half or lower half of the pointer whichever the

case may be.

THE SEVEN BAND RANGES ARE:

555M to 188M STANDARD BROADCAST 540Kc to 1600Kc

75M to 38M WEATHER BAND 4Mc to 8Mc

150Mto 75M WEATHER BAND 2Mc to 4Mc

16M SHORTWAVE 17.5Mc to 18.lMc

19M SHORTWAVE l4.9Mc to 15.5Mc

25M SHORTWAVE 11.6Mc to 12.0Mc

31M SHORTWAVE 9-4Mc to 9.8Mc

(M indicates Meters; Kc indicates Kilocycles; Mc indicates Megacycles.)

5. CONTINUOUS COVERAGE BANDS

This portable has continuous coverage from 2to 4megacycles (150 to

75 meters) and 4to 8megacycles (75 to 38 meters).

The continuous coverage band can be used by sportsmen, yachts-

men and others operating boats in the Great Lakes, Pacific Coast,

Atlantic Coast, Gulf of Mexico and Caribbean Sea areas. By tuning

to the proper frequency at the scheduled time as listed in the Weather

Broadcast Schedule (Weather Broadcast Schedules are in the back por-

tion of this book) they will be able to obtain exact up-to-the-minute as

well as predicted weather reports for the areas in which they are operat-

ing. These weather reports are vitally important in continuing or plan-

ning acruise in either the inland or off-shore waters of continental

U.S.A.

The 4to 8megacycle continuous coverage band also includes the

49 meter, 6,0 Mc to 6.2 Mc International Short Wave Band.

6. SPLIT-SECOND SCALE

This feature is provided in the upper outer edge of the dial face to

assure ease and accuracy in logging and relocating the foreign stations.

Example; Astation heard at 9.55 megacycles would be logged at 9.5

on the tuning band plus the number of seconds occurring on the split-

second scale, which in this case would be 24 seconds (i. e,: 9.5 +24).

7. RADIORG AN

The tonal characteristics of the receiver may be regulated to the listeners

preference by means of the four tone buttons below the dial The combi-

nation of these four buttons in either of their two positions offers 16

possible tonal combinations. The portion of the tonal range is shown

above each button,

8. HEADPHONES

In trains, dormitories, hospitals or schools, etc., it may be necessary

to operate the receiver without disturbing nearby persons. The use of

headphones is especially helpful for airplane travel. Special low imped-

ance Zenith Headphone Kit, part number S-18631, available through

your Zenith dealer, is easily adaptable to the chassis of the receiver. To

connect these headphones place the earphone plug into the socket pro-

vided. (See Figure 7.) Plugging the headphones into the earphone

jack automatically disconnects the speaker.

STANDARD BROADCAST

(Normal Conditions)

Use the receiver with the antenna in position as shipped from the

factory. It is not necessary to remove the Wavemagnet under nor-

mal conditions. Aloop antenna is, naturally, directional. If recep-

tion of astation is not satisfactory, rotate the entire receiver for the

position of greater signal and least interference. The directional

property is also helpful in eliminating noises caused by local elec-

trical devices.

Press The Band Selector Button Marked Broadcast.

Turn the set "On" with the left knob. Turn this control to awell

advanced position and reset to the desired volume, after astation

has been tuned in.

Tune with the right hand knob and read the standard broadcast

scale on the dial.

E. Adjust RADIORGAN for desired tone.
