Jack — lets you connect headphones for private listen-
ing, or speakers to share the sound with others.
Three Power Options — let you power the SCP-103 from in-
ternal batteries, standard AC power (with an optional AC
adapter), or your vehicle's cigarette-lighter socket (with an
optional DC adapter).
Removable Belt Clip — lets you attach the SCP-103 to your
belt for hands-free carrying when you are on the go.

PREPARATION
USING THE BELT CLIP
To attach the belt clip, align the
tab on the back of the clip with
the recess on the back of the
case, then slide the clip up until
it snaps into place.
To remove the belt clip, press
the upper part of the clip and
slide it down.
POWERING THE SCP-103
You can power your SCP-103 from any of three power sourc-
es:
• internal batteries (not supplied)
• standard AC power (with an optional AC adapter)
• your vehicle's cigarette-lighter socket (with an optional
DC adapter)
Note: Connecting an optional adapter disconnects internal
batteries.

14-1255.fm Page 6 Tuesday, July 27, 1999 10:47 AM
Using Batteries
You can power your SCP-103 from two AA batteries (not sup-
plied). We recommend RadioShack alkaline batteries. You
can also use rechargeable nickel-cadmium batteries. If you
use rechargeable batteries, you also need a battery charger
(not supplied, available at your local RadioShack store).
Cautions:
• Do not mix old and new batteries, different types of bat-
teries (standard, alkaline, and nickel-cadmium), or
rechargeable batteries of different capacities in the SCP-
103.
• Use only fresh batteries of the required size and type.
Follow these steps to install batteries.
1. Press down on the battery
compartment cover and
slide it in the direction of the
arrow, then lift it up on its
hinge to open it.
2. Install the batteries as indi-
cated by the polarity sym-
bols (+ and –) marked
inside.
3. Replace the cover.
Note: If your SCP-103 locks up, remove one of the batteries,
then reinstall it.

14-1255.fm Page 7 Tuesday, July 27, 1999 10:47 AM
Replace the batteries when the low battery icon flashes on
the display, the sound distorts, or the volume weakens.
Warning: Dispose of old batteries promptly and properly. Do
not burn or bury them.
Caution: If you do not plan to use the SCP-103 for a month
or more, remove the batteries. Batteries can leak chemicals
that can destroy electronic parts.
Important: At the end of a nickel-cadmium battery’s useful
life, it must be recycled or disposed of properly. Contact your
local, county, or state hazardous waste management authori-
ties for information on recycling or disposal programs in your
area. Some options that might be available are: municipal
curbside collection, drop-off boxes at retailers such as your
local RadioShack store, recycling collection centers, and
mail-back programs.

14-1255.fm Page 8 Tuesday, July 27, 1999 10:47 AM
Using AC Power
You can power the SCP-103 using a 3V, 300 mA AC adapter
and a size H Adaptaplug® (neither supplied). Both are avail-
able at your local RadioShack store.
Cautions:
You must use a Class 2 power source that sup-
plies 3V DC and delivers at least 300 mA. Its
center tip must be set to positive and its plug
!
DC 3V
must fit the SCP-103's
jack. Using an adapter that
does not meet these specifications could damage the
SCP-103 or the adapter.
• Always connect the AC adapter to the SCP-103 before
you connect it to AC power. When you finish, disconnect
the adapter from AC power before you disconnect it from
the SCP-103.
Follow these steps to connect an AC adapter to the SCP-103.
1. Set the adapter's voltage switch to 3V.
2. Insert the Adaptaplug into the AC
adapter's socket. Line up TIP on
the plug with +POS on the socket.
3. Insert the barrel plug into the
SCP-103's
jack.

4. Plug the AC adapter into a stan-
dard AC outlet.

Using Your Vehicle's Cigarette-Lighter Socket
You can power the SCP-103 from a vehicle’s 12V power
source (such as cigarette-lighter socket) using a 3V, 300-mA
DC adapter and a size H Adaptaplug® (neither supplied).
Both are available at your local RadioShack store.
Cautions:
You must use a power source that supplies 3V
DC and delivers at least 300 mA. Its center tip
must be set to positive and its plug must fit the

or
• Always connect the DC adapter to the SCP-103 before
you connect it to the power source. When you finish, dis-
connect the adapter from the power source before you
disconnect it from the SCP-103.
Follow these steps to power the SCP-103 from your vehicle's
cigarette-lighter socket.
1. Set the adapter's voltage
switch to 3V.
2. Insert the Adaptaplug into the
DC adapter's socket. Line up
positive (+) on the plug with
TIP on the socket.

socket and check the socket for debris. Also, check the fuse
in the adapter and your vehicle's fuse block.

CONNECTING HEADPHONES OR
AMPLIFIED SPEAKERS
To listen to the SCP-103, you need a
pair of headphones or amplified
speakers with a 1/8-inch (3.5-mm)
plug. Your local RadioShack store
carries a wide selection of head-
phones and amplified speakers.
Insert the headphones' or speakers'
1/8-inch plug into the SCP-103's
jack.
Listening Safely
To protect your hearing, follow these guidelines when you
use headphones.
• Set the volume to the lowest setting before you begin lis-
tening. After you begin listening, adjust the volume to a
comfortable level.
11
Download from Www.Somanuals.com. All Manuals Search And Download.
14-1255.fm Page 12 Tuesday, July 27, 1999 10:47 AM
• 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 headphones while operating a motor vehicle or
riding a bicycle. This can create a traffic hazard and can be il-
legal in some areas.
Even though some headphones let you hear some outside
sounds when listening at normal volume levels, they still can
present a traffic hazard.

CARE
To enjoy your cassette player for a long time:
• Keep the cassette player dry. If it gets wet, wipe it dry
immediately.
• Use and store the cassette player only in normal temper-
ature environments.
• Handle the cassette player gently and carefully. Don’t
drop it.
• Keep the cassette player away from dust and dirt.
• Wipe the cassette player with a damp cloth occasionally
to keep it looking new.
Modifying or tampering with the cassette player’s internal
components can cause a malfunction and invalidate its war-
ranty. If your cassette player is not performing as it should,
take it to your local RadioShack store for assistance.

CLEANING THE TAPE-HANDLING
PARTS
Dirt, dust, or particles of the tape's coating can accumulate on
the tape heads and other parts that the tape touches. This
can greatly reduce the performance of the SCP-103. Follow
these steps after every 20 hours of operation.

RESTORING TAPE TENSION AND
SOUND QUALITY
After you play a cassette several times, the tape might be-
come tightly wound on the reels. This can cause playback
sound quality to deteriorate.
To restore the sound quality, fast-forward the tape from the
beginning to the end of one side, then completely rewind it.
Then loosen the tape reels by gently tapping each side of the
cassette's outer shell on a flat surface.
Caution: Be careful not to damage the cassette when tap-
ping it. Do not touch the exposed tape or allow any sharp ob-
jects near the cassette.

THE FCC WANTS YOU TO KNOW
This equipment complies with the limits for a Class B digital
device as specified in Part 15 of FCC Rules. These limits pro-
vide reasonable protection against radio and TV interference
in a residential area. However, your equipment might cause
TV or radio interference even when it is operating properly.
To eliminate interference, you can try one or more of the fol-
lowing corrective measures:
• Reorient or relocate the receiving antenna.
• Increase the distance between the equipment and the
radio or TV.
• Use outlets on different electrical circuits for the equip-
ment and the radio or TV.
Consult your local RadioShack store if the problem still exists.
