PREPARATION

SUPPLYING POWER

Using Internal Battery Power

When you use batteries, your radio requires four AA batteries for operation. It also uses two AAA batteries for clock and memory station backup. We recommend alkaline batteries, such as RadioShack Cat. No. 23-552(for AA) and23-555(for the AAA size).

Caution: Always use fresh batteries of the required size and recommended type.

Follow these steps to install batteries.

 

1. Slide the battery compartment

 

cover in the direction of the arrow

illustration

and remove the cover.

2. Put the two AAA batteries into the

 

battery compartment on top of the

 

attached ribbon, as indicated by

illustration

the polarity symbols (+ and –)

 

inside the compartment.

 

3.Put the four AA batteries into the battery compartment as indicated

by the polarity symbols (+ and –)

illustration

marked outside and above the

 

compartment.

 

4. Replace the cover.

 

If the radio operates erratically or does not receive strong FM stations, replace the AA batteries. Replace the AAA batteries about every six months.

Caution: Dispose of old batteries promptly and properly. Do not burn or bury them.

Using AC Power

To power the radio with AC power, you need an AC adapter such as RadioShack Cat. No. 273-1663(not supplied).

Cautions:

You must use an AC adapter that supplies at least 6 volts and delivers at least 300 milliamps. Its center tip must be set to negative and its plug must fit the radio’s DC 6V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the radio or the adapter.

Always plug the adapter into the radio before you plug it into the AC outlet. Always unplug the AC adapter from the AC outlet before you unplug it from the radio.

1.Set the adapter’s voltage switch to 6 volts.

illustration

2.Attach the adapter’s 5.5 mm outer diameter/2.1 mm inner diameter adaptaplug to the adapter, with TIP set to –.

3.Insert the adaptaplug into the radio’s DC 6V jack.

4.Plug the adapter into a standard AC outlet.

Using Vehicle Battery Power

To power the radio from your vehicle’s cigarette-lightersocket, you need a DC adapter such as RadioShack Cat. No.273-1802(not supplied).

Cautions:

You must use a DC adapter that supplies at least 6 volts and delivers at least 300 milliamps. Its center tip must be set to negative and its plug must fit the radio’s DC 6V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the radio or the adapter.

5

Always plug the adapter into the radio before you plug it into the ciga- rette-lightersocket. Always unplug the DC adapter from the cigarettelighter socket before you unplug it from the radio.

1. Set the adapter’s voltage switch to

6V.

illustration

2.Insert the adapter’s barrel plug into the radio’s DC 6V jack.

3.Insert the adapter’s cigarettelighter plug into the vehicle’s ciga- rette-lightersocket.

Note: If the radio does not operate when you turn it on, remove the DC adapter from your vehicle’scigarette-lightersocket and check the socket for debris. Also check the fuse in your adapter and your vehicle’s fuse block.

SETTING THE CLOCK

You can use Time 1 and Time 2 to keep track of the time in two different time zones.

The alarm works only from the Time 1 setting.

Follow these steps to set the clock.

1. Turn off the radio, then press TIME 1/2 to

select Time 1 or Time 2. 1 or2 appears.

illustration

2.Press MEM/TIME. The display flashes.

3.Within 5 seconds, repeatedly press (or hold down) HOUR to set the hour.

4.Repeatedly press (or hold down) MIN to set the minute.

Notes:

PM appears when the clock displays a PM hour.AM appears when the clock displays an AM hour.

When you change the minute setting for one time zone, it automatically changes for both.

USING EARPHONES OR HEADPHONES

You can use the built-inspeaker to listen to the radio. Or, you can use stereo earphones or headphones (not supplied) with1/8-inchplug to listen privately.

Insert the earphones’ plug into the radio’s jack.

illustration

Note: Thebuilt-inspeaker disconnects when you connect earphones or headphones.

Listening Safely

To protect your hearing, following these guidelines when you use earphones or headphones.

Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.

Do not listen at extremely high volume levels. Extended high volume listening can lead to permanent hearing loss.

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 wear earphones/headphones while operating a motor vehicle or riding a bicycle. This can create a traffic hazard and could be illegal in some areas.

Even though some earphones/headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

7

USING THE STAND

You can use the radio’s stand to set the radio at an angle so you can easily see the display. Simply lift the stand away from the back of the radio and set the radio on a flat surface.
