BATTERIES REQUIRED:
1 " A " Battery, 412 Volt, Eveready No. 746 or equivalent.
1 " B " Battery, 67 % Volt, Eveready No. 467 or equivalent.

1. INSTALLATION OF "A" BATTERY
To replace or install battery, open rear cover, remove old battery and pull out connector and insert same into new battery; then very carefully push battery into space provided for it, making certain that battery is pushed forward to front of cabinet,

2. INSTALLATION OF "B" BATTERY
Swing down the battery holding clip, remove old battery and pull out connector and insert same into new battery; then slip into space provided for it and swing holding clip upward to press against battery.

3. TO OPERATE ON BATTERIES: Open rear cover, turn changeover switch knob to battery position. The left hand knob in front operates the volume control and turns set on and off. Adjust to desired volume. The right hand knob is calibrated in kilocycles (KC) with the final zero omitted.

4. SW OPERATION: Open rear cover, turn band switch to SW position. It will be necessary to connect an antenna wire of about 30 to 50 feet to the single wire coming through the rear of chassis. The short-wave portion of the dial is calibrated in megacycles (MC) and in meters (M).

5. TO OPERATE ON ELECTRIC: Open rear cover, turn changeover switch knob to electric position, Remove line cord and plug into nearest wall outlet; then proceed to operate receiver as outlined in previous paragraph A slot is provided in the lower part of the cover so that it may be closed.

6. NOTE: If receiver does not operate on DC after being turned or for a few minutes, reverse the line cord in the wall outlet, If the receiver is to be operated for a long period of time on AC or DC or it is to be placed in storage, we recommend that the batteries be removed and stored in a cool place. This will insure maximum battery life

7. CAUTION: Be sure to turn the volume control knob " OFF (extreme counter clock-wise position) when receiver is not in use to avoid discharge of batteries. Do not leave exhausted batteries in receiver.

8. REAR COVER WILL NOT STAY CLOSED: This is generally due to batteries not being properly installed. Refer to previous paragraph on battery installation.

9. ELECTRICAL SPECIFICATIONS: This receiver employs a 4 - tube superheterodyne circuit of 8 tuned stages. The frequency range is from 1650 to 540 KC and 18.3 to 5.8 MC. The tube compliment is as follows: 1-1R5, 1-174, 1-155 and 1-354. See diagram for location of batteries and tubes.

10. IF SET DOES NOT OPERATE ON ELECTRIC OR BATTERY: Check and be sure tubes are firmly in position in their sockets. If Tubes have a milky white formation they should be removed and tested or replaced.

11. SET DEVELOPS MICROPHONIC HOWL: Check 155 Tube. Replace with new tube if necessary.
