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.

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 signals.

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).

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 receiver. 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 recommended 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- (Illus) ing it in the direction of the arrow below.

2.Slide three AA batteries into the compartment according to

the polarity symbols (+ and –)

(Illus)

marked inside.

 

3. Close the cover.

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

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 optional 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 specifications. 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.

20-227.fm Page 6 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 barrel 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 optional 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.

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 barrel 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 shortwave reception, pull up the telescoping antenna’s base, then fully extend the an-

tenna and position it for the best recep- (Illus) 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 highvolume 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.
