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 cl ip up until
it snaps into place.
To remove the belt clip, press
the upper part of the clip and

POWERING THE SCP-103
You can power your SCP-103 from an y of th ree pow er s our ces:
• internal batteries (not supplied)
• standard AC power (with an optional AC adapter)
• your vehicle's cigarette-lighter socket (with an optional
DC adapter)
Connecting an optional adapter disconnects internal
Note:
batteries.

14-1255.fm Page 6 Tuesday, July 27, 1999 10:47 AM
Using Batteries
You can power your SCP-103 fro m two AA ba tteries (not su pplied). 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 batter ies, dif ferent type s 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 indicated by the polarity symbols (+ and –) marked
inside.
3. Replace the cover.
If your SCP-103 locks up, remove one of the batte ries ,
Note:
then reinstall it.
6
14-1255.fm Page 7 Tuesday, July 27, 1999 10:47 AM
Replace th e batteries when the low battery icon fla shes on
the display, the sound distorts, or the volume weakens.
Warning:
Dispose of old bat ter ie s promp tly and p rop erly . 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 ha za rdou s w as te ma nagement authorities 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.

Listening Safely
To protect your hearing, follow these guidelines when you
use headphones.
• Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a
comfortable level.

11
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 illegal 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.

• Keep the cassette player dry. If it gets wet, wipe it dry
immediatel y.
• 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.

RESTORING TAPE TENSION AND
SOUND QUALITY
After you play a cassette several times, the tape might become 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:
ping it. Do not touch the exposed tape or allow any sharp objects near the cassette.
