FEATURES

Your RadioShack DX-397 AM/FM/SW 12-Band Portable Receiver

brings you the voices of the world. Simple to operate, the receiver

tunes mediumwave (MW or AM), FM, and shortwave stations. In

the 10 international shortwave bands, you can hear news broad-

casts and other programs from sources around the world, such as

Radio Japan, Israel Radio, the British Broadcasting Corporation,

and Radio Australia.

Your receiver’s features include:

Light and Compact Design — lets you carry the receiver with you

wherever you go.

Two Built-In Antennas — provide good reception of received sig-

nals.

Earphone Jack — lets you connect earphones or headphones for

private listening.

Three Power Options — let you power the receiver from batteries,

standard AC power (with an optional AC adapter), or your vehicle’s

battery (with an optional DC cigarette lighter adapter).

Shortwave Band Coverage List — this Owner’s Manual lists the

most popular U.S. and international shortwave stations, so you can

quickly tune to these stations.

PREPARATION

CONNECTING TO POWER

You can power the receiver from internal batteries, standard AC

power, or your vehicle’s battery.

Installing Batteries

You can use three AA batteries (not supplied) to power the receiv-

er. For the best results and longest life, we recommend alkaline

batteries such as RadioShack Cat. No. 23-552.

Cautions:

• Always use fresh batteries of the required size and recom-

mended type.

• Do not mix old and new batteries, different types of batteries

(standard, alkaline, or rechargeable), or rechargeable batteries

of different capacities.

Follow these steps to install the batteries.

1. Open the battery compartment cover by

pressing on the dotted portion and slid-

ing it in the direction of the arrow below.

2. Slide three AA batteries into

the compartment according to

the polarity symbols (+ and –)

marked inside.

3. Close the cover.

Cautions:

• If you will not be using battery power or if you will only use an

adapter for several months, remove the batteries.

• Dispose of old batteries promptly and properly.

Using Standard AC Power

To power the receiver from standard AC power, you need an op-

tional AC adapter, such as Cat. No. 273-1662.

Note: Connecting an AC adapter disconnects internal batteries.

Cautions:

• The AC adapter must be capable of delivering 4.5 volts, its

center tip must be set to negative, it must deliver at least 200

milliamps, and its barrel plug must properly fit the receiver’s DC

IN 4.5V jack. The recommended adapter meets these specifica-

tions. Using an adapter that does not meet these specifications

could damage the receiver or the adapter.

• When you finish using the AC adapter, unplug it from the AC

outlet first, then disconnect it from the receiver.

Follow these steps to use AC power.

(Illus)

20-227.fm Page 5 Wednesday, August 4, 1999 10:13 AM

1. Set the adapter’s voltage switch to 4.5V.

2. Line up the 5.5 mm outer diameter/2.1 mm inner diameter bar-

rel plug with the adapter’s socket so it reads –TIP, and insert

the plug into the socket.

3. Insert the barrel plug into the receiver’s DC IN 4.5V jack.

4. Plug the adapter into a standard AC outlet.

Using Vehicle Battery Power

To power the receiver from your vehicle’s battery, you need an op-

tional DC cigarette lighter adapter, such as Cat. No. 270-1560.

Cautions:

• The DC cigarette lighter adapter must be capable of delivering

4.5 volts, its center tip must be set to negative, it must deliver

at least 200 milliamps, and its barrel plug must properly fit the

receiver’s DC IN 4.5V jack. The recommended adapter meets

these specifications. Using an adapter that does not meet

these specifications could damage the receiver or the adapter.

• Always plug the DC cigarette lighter adapter into the receiver

before you plug it into your vehicle's cigarette-lighter socket.

Always unplug the adapter from the vehicle's cigarette-lighter

socket before you unplug it from the receiver.

Follow these steps to power the receiver from your vehicle’s battery.

20-227.fm Page 6 Wednesday, August 4, 1999 10:13 AM

1. Set the DC cigarette lighter adapter’s voltage switch to 4.5V.

2. Line up the 5.5 mm outer diameter/2.1 mm inner diameter bar-

rel plug with the adapter’s socket so it reads –TIP, and insert

the plug into the socket.

3. Insert the adapter’s barrel plug into the receiver’s DC IN 4.5 V

jack.

4. Insert the adapter’s plug into the vehicle’s cigarette-lighter

socket.

ADJUSTING THE ANTENNAS

FM/SW — For the best FM and short-

wave reception, pull up the telescoping

antenna’s base, then fully extend the an-

tenna and position it for the best recep-

tion.

MW (AM) — For the best MW reception,

rotate the receiver. The receiver uses a

built-in antenna for this band.

CONNECTING AN EARPHONE/

HEADPHONES

For private listening, you can plug optional mono headphones or an

earphone with a 1/8-inch (3.5 mm) plug (both available at your local

RadioShack store) into the jack on the left side of the receiver.

This automatically disconnects the internal speaker.

Listening Safely

To protect your hearing, follow these guidelines when you use an

earphone or headphones.

• Do not listen at extremely high volume levels. Extended high-

volume listening can lead to permanent hearing loss.

• Set the volume to the lowest setting before you begin listening.

After you begin listening, adjust the volume to a comfortable

level.

• Once you set the volume, do not increase it. Over time, your

ears adapt to the volume level, so a volume level that does not

cause discomfort might still damage your hearing.

Traffic Safety

Do not use an earphone or headphones with your receiver when

operating a motor vehicle or riding a bicycle in or near traffic. Doing

so can create a traffic hazard and could be illegal in some areas.

If you use an earphone or headphones with your receiver, be very

careful. Do not listen to a continuous broadcast. Even though some

earphones or headphones let you hear some outside sounds when

listening at normal volume levels, they still can present a traffic haz-

ard.

OPERATION

1. To turn on the receiver, slide POWER to ON.

2. Set SW/MW/FM to the desired band. To tune a shortwave

broadcast, set SW/MW/FM to one of the SW bands (1to 10).

See “International Frequencies” on Page 12 for information

about each SW band.

3. Adjust TUNING to tune to the

desired station then adjust

either of the radio’s antennas

if necessary (see “Adjusting

the Antennas” on Page 7).

The TUNING indicator on the

front of the receiver lights

when a station is properly

tuned.

4. Adjust

VOLUME to a comfort-

able listening level.

5. Slide POWER to OFF to turn off the receiver.
