FEATURES

Your Radio Shack DX-392 PLL All-

Band Portable Receiver with Cassette

Recorder brings the voices of the world

to you. In the 13 international short-

wave (SW) bands, you can hear news

broadcasts and other programs from

sources such as the British Broadcast-

ing Company, Radio Cairo, and Radio

Moscow.

You can get emergency information

firsthand by listening to amateur radio

broadcasts, which include single side-

band (SSB) voice transmissions and

continuous wave (CW) Morse code

transmissions.

In the longwave (LW) band, you

sometimes hear hurricane reports,

ship-to-shore calls, and other marine

and aeronautical services. You can

tune to local broadcasts in the FM and

medium-wave (MW) bands. (In the

United States, we commonly call the

MW band the AM band.) In addition,

you can use the built-in cassette re-

corder to record your favorite pro-

grams live or at a preset time.

PREPARATION

SETTING THE MW (AM)

TUNING INCREMENT

In the United States, the Federal Com-

munications Commission (FCC) as-

signs frequencies for stations in the

MW band in 10-kilohertz increments.

(In the United States, we commonly

call the MW band the AM band.) In Eu-

rope and some other parts of the

world, MW frequencies are assigned in

9-kilohertz increments.

The MW STEP switch is located in-

side the battery compartment. Before

you install the back-up batteries, set

the switch to 9k or 10k using the fol-

lowing guidelines:

• If you are in the United States,

Canada, or another North or

South American country, be sure

the switch is set to 10k.

• If you are in a country where

the AM frequency increments

are 9 kHz, set the switch to 9k.

INSTALLING BACK-UP

BATTERIES

Back-up batteries power the receiver’s

clock and the display and save the sta-

tions stored in memory if the receiver’s

primary power source is interrupted.

The receiver uses three AA batteries

for back-up power. For the best perfor-

mance, we recommend alkaline bat-

teries, such as Radio Shack Cat. No.

23-552.

Note: You cannot operate the receiver

using only the back-up batteries. If you

press POWER when the back-up bat-

teries are the only available power

source,

Eflashes on the display.

Follow these steps to install the back-

up batteries.

1. Remove the battery compart-

ment’s cover by pushing the cover

in the direction of the arrow.

2. Install three AA batteries, according

to the polarity symbols (+ and –)

marked next to the compartment.

For easy removal, place the bat-

teries on top of the lift-out ribbon.

20-219.fm Page 6 Wednesday, August 4, 1999 9:23 AM

3. Replace the cover, or install addi-

tional batteries for primary power

as described in “Internal Battery

Power.”

To check the back-up batteries’ power

level, disconnect the receiver from the

primary-power source. Then look at

the receiver’s display. If it is dim, re-

place the back-up batteries.

CONNECTING TO

PRIMARY POWER

You can power the receiver from inter-

nal batteries, standard AC power, or

your vehicle’s battery.

Internal Battery Power

Your receiver uses four D batteries.

For the best performance, we recom-

mend alkaline batteries, such as Radio

Shack Cat. No. 23-550.

Follow these steps to install batteries

for use as the primary power source.

1. Remove the battery compart-

ment’s cover by pushing the cover

in the direction of the arrow.

2. Slide four D batteries into the

compartment, according to the

polarity symbols (+ and –) marked

next to the compartment. For easy

removal, place the batteries on

top of the lift-out ribbon.

3. Replace the cover.

To check the primary-power batteries,

turn off the receiver. The battery pow-

er indicator appears on the display for

several seconds. Fresh batteries

show a power level of 7. If the indica-

tor shows a power level of 2 or below,

replace the primary-power batteries.

Note: If you press RADIO POWER to

turn on the receiver when the primary-

power batteries are dead, Eflashes on

the display if back-up batteries are in-

stalled.

AC Power

With an optional AC adapter, such as

Radio Shack Cat. No. 273-1664, you

can power the receiver from standard

AC power.

Caution: You must use an AC adapter

that supplies 6 volts with the center tip

set to negative. It must deliver at least

400 milliamps, and its plug must prop-

erly fit the receiver’s DC IN 6V jack. Us-

ing an adapter that does not meet

these specifications could damage the

20-219.fm Page 7 Wednesday, August 4, 1999 9:23 AM

receiver or the adapter.

Follow these steps to use AC power.

1. Set the adapter’s voltage switch to

6V.

2. Line up the 5.5 mm outer diam-

eter/2.1 mm inner diameter

barrel plug with the adapter’s

socket so it reads –TIP, and insert

the plug.

3. Insert the barrel plug into the re-

ceiver’s DC IN 6V jack.

4. Plug the adapter into a standard

AC outlet.

Note: Using an adapter disconnects

the primary power batteries.

DC Power

With an optional DC adapter, such as

Radio Shack Cat. No. 270-1562, you

can power the receiver from your vehi-

cle’s battery.

Cautions:

• You must use a DC adapter that

supplies 6 volts with the center tip

set to negative. It must deliver at

least 400 milliamps, and its plug

must properly fit the receiver’s DC

IN 6V jack. Using an adapter that

does not meet these specifica-

tions could damage the receiver

or the adapter.

• To protect your vehicle’s electrical

system, be sure the adapter is

connected to the cigarette-lighter

socket only when it is also con-

nected to the receiver.

• Follow these steps to use DC

power.

1. Set the adapter’s voltage switch to

6V.

2. Line up the 5.5 mm outer diam-

eter/2.1 mm inner diameter

barrel plug with the adapter’s

socket so it reads –TIP, and insert

the plug.

3. Insert the adapter’s barrel plug

into the receiver’s DC IN 6V jack.

4. Insert the adapter’s plug into the

vehicle’s cigarette-lighter socket.

Note: Using an adapter disconnects

the primary-power batteries.

20-219.fm Page 8 Wednesday, August 4, 1999 9:23 AM

USING THE FOLDING

STAND AND MEMO PAD

You can position the receiver more se-

curely and possibly improve the sound

by resting the receiver on its stand.

Lift the latch on the back of the receiver

to open the stand. You can use the

memo pad under the receiver’s stand

to record helpful information, such as

the memory location numbers of your

favorite stations.

USING THE RECEIVER

TURNING THE

RECEIVER ON/OFF

Press RADIO POWER to turn on the re-

ceiver, then adjust the volume.

The display shows the band, frequen-

cy, and signal strength. (A reading of 7

indicates the strongest signal.)

Press RADIO POWER again to turn off

the receiver.

TUNING

Selecting the Band

Press FM, MW, LW, or SW to select the

band. (Press MW for AM.) To select a

smaller band within the SW band,

press

METER, then enter the desired

band by pressing its labeled button on

the keypad.

Direct-Access Tuning

Follow these steps to directly tune to a

station.

1. Press FREQ. The frequency dis-

play disappears.

20-219.fm Page 9 Wednesday, August 4, 1999 9:23 AM

2. Press the number buttons (and

decimal button where appropriate)

to enter the frequency.

If you make a mistake, press C

(cancel) to erase the last digit.

If you wait more than 15 seconds

to press a button, the previous fre-

quency returns to the display and

you must begin again at Step 1.

3. Press ENTER. The selected fre-

quency appears.

Using the Rotary Dial

You can select a higher or lower fre-

quency by turning the ROTARY TUNING

knob up or down.

Set FAST/FINE/LOCK to selectthe rota-

ry tuning increments or to lock the RO-

TARY TUNING dial. If you select FAST,

the rotary tuning increments are the

same as when you use the MANUAL/

AUTO or keys. If you select

FINE, the tuning increments are small-

er so you can fine tune the frequency,

as shown in the following table.

You can also set FAST/FINE/LOCK to

lock the ROTARY TUNING dial. This

prevents you from accidentally chang-

ing the frequency.

Note: This locks only the ROTARY

TUNING dial. For information about

locking the front-panel buttons, see

“Locking the Controls” on Page 22.
