PREPARATION
CONNECTING POWER
The SCP-101 operates from any of these power sources:
• internal batteries (not supplied)
• standard AC power (using an optional AC adapter)
• vehicle battery power (using an optional DC adapter)
Using Internal Batteries
Your SCP-101 requires two AA batteries (not supplied for
power. For the best performance and longest life, we rec-
ommend RadioShack alkaline batteries.
Cautions:
• Use only fresh batteries of the required size and rec-
ommended 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 batteries.
1. Press and slide the battery compartment cover in the
direction of the arrow until it stops.
2. Lift the curved edge of the cover.
Caution: The battery compartment cover is hinged
and cannot be removed.
3. Place the batteries in the compartment and on top of
the attached ribbon, as indicated by the polarity sym-
bols (+ and –) marked on outside the compartment.
4. Close the cover.
When the sound gets distorted or weak, or the SCP-101
stops operating properly, replace the batteries.
Warning: Dispose of old batteries promptly and properly.
Do not burn or bury them.
Caution: If you do not plan to use the SCP-101 with bat-
teries for a week or more, or if you plan to use only stan-

dard AC or vehicle power, remove the batteries. Batteries
can leak chemicals that can destroy electronic parts.
USING AC POWER
You can power the SCP-101 using a 3V, 300-mA AC
adapter and a size H Adaptaplug®(neither supplied).
Both are available at your local RadioShack store.
Cautions:
You must use a Class 2 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 SCP-101's DC 3V jack. Using an
adapter that does not meet these specifications could
damage the SCP-101 or the adapter.
• Always connect the AC adapter to the SCP-101 be-
fore you connect it to AC power. When you finish,
disconnect the adapter from AC power before you
disconnect it from the SCP-101.

Follow these steps to power the SCP-101 from standard
AC power.
1. If the adapter has a voltage switch, set the switch to
3V.
2. Insert the Adaptaplug into the adapter’s cord so it
reads TIP +.
3. Insert the Adaptaplug into the SCP-101’s DC 3V jack.
4. Plug the adapter into a standard AC outlet.
Note: Connecting an adapter to the SCP-101's DC 3V
jack disconnects the internal batteries.
USING VEHICLE BATTERY POWER
You can power the SCP-101 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 sup-
plied). Both are available at your local RadioShack store.

age the SCP-101 or the adapter.
• Always connect the DC adapter to the SCP-101 be-

finish, disconnect the adapter from the power source
before you disconnect it from the SCP-101.
Follow these steps to power the SCP-101 from DC power.

3. Insert the Adaptaplug into the SCP-101's DC 3V jack.
Note: Connecting an adapter to the SCP-101's DC
3V jack disconnects the internal batteries.
4. Plug the other end of the DC adapter into the vehi-
cle's cigarette-lighter socket.
CONNECTING HEADPHONES/
SPEAKERS
To listen to the SCP-101, connect stereo headphones or
amplified speakers (neither supplied) equipped with a 1/8-
inch (3.5-mm) stereo plug to PHONES. Your local
RadioShack store sells a wide variety of stereo head-
phones and amplified speakers.

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.
• Do not listen at extremely high volume levels.
Extended high-volume listening can lead to perma-
nent 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 dam-
age your hearing.
Traffic Safety
• Do not wear headphones while operating a motor
vehicle or riding a bicycle. This can cause a traffic
hazard and could be illegal in some areas.
• Even though some headphones are designed to let
you hear outside sounds when you listen at normal
volume levels, they still can present a traffic hazard.

USING THE BELT CLIP
For hands-free carrying, install the supplied belt clip.
To install the belt clip, place it below and between the two
guides on the back of the player. Then slide the clip in the
opposite direction of the arrow until it snaps into place.
To remove the belt clip, lift the tab at the point marked
LIFT, then slide the clip in the direction of the arrow.

RADIO OPERATION
Follow these steps to set up, tune and play the radio.
1. Connect either headphones or amplified speakers to
PHONES.
2. Set TAPE/RADIO to RADIO.
3. Set FM ST/FM/AM to the desired band.
4. Adjust VOL to the desired listening level.
5. Turn TUNING to select the station.
Notes:
• If you set the radio to FMST, FM ST (FM Stereo)
lights when you receive a stereo FM broadcast.
• To improve the reception of a weak FM station, set
FM ST/FM/AM to FM. The signal changes from ste-
reo to monaural, and reception generally improves.
•Set
E-BASS to ON for an enhanced bass effect. Set
it to OFF for normal bass sound.
6. To turn off the radio, set TAPE/RADIO to TAPE.

TAPE TIPS
STORING CASSETTE TAPES
Do not expose cassette tapes to high temperatures, high
humidity, dust or dirt, or motors, transformers, or other
sources of strong magnetic fields.
RESTORING TAPE TENSION AND
SOUND QUALITY
After you play a cassette tape 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 re-
wind 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
tapping it. Do not touch the exposed tape or allow any
sharp objects near the cassette.

CARE AND MAINTENANCE
Your Optimus SCP-101 AM-FM Stereo Cassette Player
is an example of superior design and craftsmanship. The
following suggestions will help you care for the SCP-101
so you can enjoy it for years.
• Keep the SCP-101 dry. If it gets wet, wipe it dry
immediately.
• Use and store the SCP-101 only in normal tempera-
ture environments.
• Handle the SCP-101 gently and carefully. Don’t drop
it.
• Keep the SCP-101 away from dust and dirt.
• Wipe the SCP-101 with a damp cloth occasionally to
keep it looking new.
Modifying or tampering with the SCP-101’s internal com-
ponents can cause a malfunction and might invalidate its
warranty. If your SCP-101 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 accumu-
late on the tape head and other parts that the tape touch-
es. This can greatly reduce the SCP-101’s performance.

After every 20 hours of tape player operation, follow
these steps to clean the tape-handling parts or use a Ra-
dioShack cassette deck cleaning kit.
1. Remove the batteries and disconnect any other
power source.
2. Open the cassette compartment door, remove any
cassette tape inside and set TAPE/ RADIO to TAPE.
3. Press to expose the tape head.
4. Use a cotton swab dipped in tape head-cleaning
solution or denatured alcohol to gently clean the cap-
stans, tape guides, pinch rollers, and tape head.

FCC INFORMATION
The SCP-101 complies with the limits for a Class B digital
device as specified in Part 15 of
FCC Rules . These limits
provide reasonable protection against radio and TV inter-
ference in a residential area. However, your SCP-101
might cause TV or radio interference even when it is op-
erating properly. To see if your SCP-101 is causing the
interference, turn it off. If the interference goes away,
your SCP-101 is causing it. To eliminate interference, try
the following:
• Increase the distance between the SCP-101 and the
radio or TV.
• Use outlets on different electrical circuits for the SCP-
101 and the radio or TV.
Consult your local RadioShack store if the problem still
exists.
