O HELP YOU 
ENJOY YOUR NEW 


RADIO PHONOGRAPH 


Operating The Phonograph 


This Zenith radio-phonograph gives you a new conception in record 
playing enjoyment. It will play fourteen 10-inch or twelve 12-inch or 
twelve 10- and 12-inch records intermixed, at one loading. It features the 
revolutionary Zenith Cobra Tone Arm which has been proved so superior in 
record reproducing quality that hundreds of them have been purchased by 
radio stations for reproducing records. It has an automatic shut-off feature 
which operates after the last record has been played. The changer has a mini- 
mum of moving parts. Electric controls operate the record changing mech- 
anism lightning fast, with a change cycle of less than 344 seconds. The 
Cobra Tone Arm has a “floating filament” which rests in the record grooves 
with so little pressure that records sound like new as much as ten times 
longer. The Cobra reproduces records with rich, true-fidelity tone quality, 
and it is not affected by humidity or temperature changes.

UNPACKING @ 


The record changer has been securely packed to avoid damage in ship- 
ment. It is important that all packing material be removed before the 
changer is operated. Ordinarily, the dealer from whom you purchased the 
set will unpack and install it. If, however, it is necessary for some other 
person to make the installation, he should first read the tags attached. to the 
unit, and carefully remove the strips, bolts, and other packing material. 
After this has been done, the changer must be “floated” for proper opera- 
tion. To do this, use a wide-blade screw driver, and turn the four mounting 
bolts (see Fig. 1) clockwise until the heads of the bolts are flush with 
the mounting plate. 


IMPORTAN-T 


The phono pre-amplifier is spring mounted in the rear of the cabinet. 
This must also be “floated” by removal of the cardboard packing strip. 


HOW TO OPERATE 


Tone and Volume Control: Use of the Radiorgan will give you added 
listening pleasure from your records. With it you can change the bass and 
treble response for the tone effect you prefer. Be sure to read the section on 
the Radiorgan contained in the instruction book covering the operation of 
the radio. The volume of record reproduction is regulated by the Volume 
Control exactly the same as for radio reception.

DLE to the LOAD position.

However, should you desire to stop it before all of the records have been © 
played, proceed as follows: )

or filament in contact with the record.

~ Fig. 2. Removing Record Stack 


Manual Operation: Old or odd sized records are not intended for auto- 
matic use and must be played manually, that is, singly, as on a non-automatic 
record player. For manual operation, set the MANUAL AUTOMATIC 
SWITCH to the MANUAL position (see Fig. 1). With the switch in this 
position the tone arm is free and may be picked up and placed on the start- 
ing groove of the record. 


CHANGING THE NEEDLE CARTRIDGE 


The cartridge of the Cobra Tone Arm will usually play many thousands 
of times. Should it become necessary to change the cartridge because of 
wear or mishandling, this can be done very easily without tools of any kind. 
A replacement cartridge may be purchased from your Zenith dealer at 
moderate cost. 


~ 


If it becomes necessary to change the Needle Cartridge, proceed as 
follows: | 

1. Set the RECORD CHANGER ON/OFF SWITCH to OFF. 

2. Raise the TONE ARM as far as it will go without forcing. 


3. Grasp the RED NEEDLE CARTRIDGE with the fingertips, and gently 
pull it straight out.

4. Insert a NEW NEEDLE CARTRIDGE, and push it in place gently 
and carefully with the thumb. The cartridge is so designed that it cannot 
be put in backwards . . . it will fit in only one way. Be careful to place 
it in the socket at the right angle so as to eliminate the possibility of damage 
to the cartridge or the socket. (Study Fig. 3). 


RECORDS—IMPORTANT 


1. Excessive scratch and poor tone quality are usually caused by worn or 
warped records. The amount of surface and background noise on new rec- 
ords will vary, depending on the quality of manufacture, the type of music 
recorded, and the care given the records. Should you hear squeaking caused 
by friction between the spindle and the records, this can be eliminated by a 
thin coat of wax or paraffin on the spindle. - 

2. Never allow.records to remain on the spindle when the Record Changer 
is not in use. To do so may result in warping of records and failure of the 


changer to play such records. 
3. Thin substandard records may drop double into playing position. 
4. Thick substandard records may not slide down in playing position. 


5. Occasional soft records may chip and wear out quickly at the center pole. 


6. Warped or dished records, or records with bulging center holes will slip 
on the turntable stack and not properly drive records above. This causes 
““wows” and uneven speeds. | 


CARE OF RECORDS 


A small effort on your part will insure long life for your records. Do 
not expose them to heat from the sun, radiators or stoves. Store your records 
in albums in a cool, dry place, resting vertically or horizontally. Remove 
dust and dirt with a soft cloth, using a light circular motion. Even a fine 
film of dust often contains abrasive particles which, when ground against 
the record surface by the needle, may cause very rapid wear. 


SER VICE 


Your Zenith radio-phonograph has been carefully constructed. Its op- 
eration is simple and reliable. However, as is the case with all mechanical 
and electrical devices, minor adjustments may occasionally be necessary. 
Should this professional service be required, call your authorized Zenith 


dealer.
