PREPARATION  
CONNECTING POWER  
Using Batteries  
To power the SCP-100 with batteries, you need two  
AA batteries (not supplied). We recommend alkaline  
batteries, such as RadioShack Cat. No. 23-557.  
Follow these steps to install batteries.  
1. Pull up the black cassette compartment latch  
and pull open the cassette compartment door.  
Illust.

14-1248.fm Page 6 Friday, July 2, 1999 12:46 PM  
2. Press the battery compartment cover’s tab in the  
direction of the arrow and lift off the cover.  
Illust.  
3. Install the batteries as indicated by the polarity  
symbols (+ and –) marked inside the compart-  
ment, with both batteries over the ribbon.  
Cautions:  
Use only fresh batteries of the required size  
and type.  
Do not mix old and new batteries, different  
types of batteries (standard, alkaline, or  
rechargeable), or rechargeable batteries of  
different capacities.  
4. Replace the battery compartment cover, then  
close the cassette compartment door and latch.  
6
 
14-1248.fm Page 7 Friday, July 2, 1999 12:46 PM  
If the SCP-100 does not operate properly or if the  
sound becomes weak or distorted, replace the batter-  
ies.  
Cautions:  
• Always dispose of old batteries promptly and  
properly.  
• Never leave dead, old, or weak batteries in the  
SCP-100. They can leak chemicals and corrode  
or damage electronic circuits.  
• If you do not plan to power the SCP-100 with  
batteries for several days, or if you plan to power  
it using only an AC or DC adapter, remove the  
batteries to protect the SCP-100 from possible  
battery leakage.  
Using AC Power  
To power the SCP-100 with standard AC power, you  
need an optional AC adapter, such as RadioShack  
Cat. No. 273-1654.  
7
 
14-1248.fm Page 8 Friday, July 2, 1999 12:46 PM  
Cautions:  
• The recommended AC adapter supplies 3 volts  
and delivers at least 250 milliamps. Its center tip  
is set to negative, and its barrel plug correctly fits  
the SCP-100’s DC 3V jack. Using an adapter that  
does not meet these specifications could dam-  
age the SCP-100 or the adapter.  
• Always connect the adapter to the SCP-100’s DC  
3V jack before you connect it to the AC outlet.  
Then disconnect the adapter from the AC outlet  
before disconnecting it from the SCP-100.  
Follow these steps to power the SCP-100 from a  
standard AC outlet.  
1. Set the adapter’s voltage switch to 3V.  
2. Insert the adapter’s 3.4 mm outer diameter/1.3  
mm inner diameter barrel plug into the adapter’s  
cord so it reads –TIP.  
3. Pull out the attached rubber plug from the SCP-  
100’s DC 3V jack.

14-1248.fm Page 9 Friday, July 2, 1999 12:46 PM  
4. Insert the adapter’s barrel plug into the SCP-  
100’s DC 3V jack.  
Illust.  
5. Plug the adapter into a standard AC outlet.  
Illust.  
Notes:  
• Internal batteries (if installed) automatically dis-  
connect when you plug the AC adapter into the  
SCP-100.  
9
 
14-1248.fm Page 10 Friday, July 2, 1999 12:46 PM  
• Disconnect the adapter and reinsert the jack’s  
rubber plug when you are not using the SCP-  
100.  
Using Vehicle Battery Power  
To power the SCP-100 from your vehicle’s cigarette-  
lighter socket, you need an optional DC adapter,  
such as RadioShack Cat. No. 270-1560.  
Cautions:  
• The recommended DC adapter supplies 3 volts  
and delivers at least 250 milliamps. Its center tip  
is set to negative, and its barrel plug correctly fits  
the SCP-100’s DC 3V jack. Using an adapter that  
does not meet these specifications could dam-  
age the SCP-100 or the adapter.  
• Always connect the adapter to the SCP-100’s DC  
3V jack before you connect it to the cigarette-  
lighter socket. Then disconnect the adapter from  
the cigarette-lighter socket before disconnecting  
it from the SCP-100.  
10  
 
14-1248.fm Page 11 Friday, July 2, 1999 12:46 PM  
Follow these steps to power the SCP-100 from your  
vehicle’s cigarette-lighter socket.  
Illust.  
1. Set the adapter’s voltage switch to 3V.  
2. Insert the adapter’s 3.4 mm outer diameter/1.3  
mm inner diameter barrel plug into the adapter’s  
cord with the tip set to negative (–).  
3. Pull out the attached rubber plug from the SCP-  
100’s DC 3V jack.  
4. Insert the adapter’s barrel plug into the SCP-  
100’s DC 3V jack.  
5. Plug the adapter into the vehicle’s cigarette-  
lighter socket.  
11  
 
14-1248.fm Page 12 Friday, July 2, 1999 12:46 PM  
Notes:  
• If the SCP-100 does not operate properly when  
you use DC power, be sure the cigarette-lighter  
socket is clean and that the adapter’s plug is  
pushed all the way into the socket.  
• Disconnect the adapter and reinsert the jack’s  
rubber plug when you are not using the SCP-  
100.  
• Internal batteries (if installed) automatically dis-  
connect when you plug the adapter into the DC  
3V jack.

14-1248.fm Page 13 Friday, July 2, 1999 12:46 PM  
CONNECTING THE EARBUDS  
OR SPEAKERS  
To listen to your SCP-100, you need to connect the  
supplied sports earbuds or a pair of amplified speak-  
ers (not supplied) with a 1/8-inch mini plug.  
Pull out the attached rubber plug from the SCP-100’s  
PHONES jack, then plug in the earbuds’ or speakers’  
1/8-inch plug.  
Illust.  
When you are not using your SCP-100 and earbuds  
or speakers are disconnected, insert the rubber plug  
back into the PHONES jack to protect against mois-  
ture and dust.  
13  
 
14-1248.fm Page 14 Friday, July 2, 1999 12:46 PM  
Listening Safely  
To protect your hearing, follow these guidelines when  
you use the earbuds.  
• 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 per-  
manent 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 the earbuds while operating a motor ve-  
hicle or riding a bicycle. This can cause a traffic haz-  
ard and can be illegal in some areas.  
14  
 
14-1248.fm Page 15 Friday, July 2, 1999 12:46 PM  
Even though some earbuds are designed to let you  
hear some outside sounds when listening at normal  
volume levels, they still can present a traffic hazard.  
USING THE BELT CLIP  
For hands-free carrying, slide the belt clip over your  
belt.  
To remove the belt clip, use a Phillips screwdriver to  
loosen the screw holding the clip. Then lift off the clip.  
Illust.  
To replace the belt clip, position it as shown, put the  
tip of the screw back into the screw hole, and tighten  
the screw with a screwdriver.

TAPE TIPS  
Tape Quality  
For the best performance, use only regular length  
(60- or 90-minute) cassette tapes. We do not recom-  
mend long-playing cassette tapes, such as C-120s,  
because they are extremely thin and can easily tan-  
gle in the playback mechanism.  
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 turn it  
over and completely fast-forward the other side.  
Then loosen the tape reels by gently tapping each  
side of the cassette’s outer shell on a flat surface.  
21  
 
14-1248.fm Page 22 Friday, July 2, 1999 12:46 PM  
Caution: Be careful not to damage the cassette  
when tapping it. Do not touch the exposed tape or al-  
low any sharp objects near the cassette.

PERSONAL SAFETY LIGHT  
The personal safety light is a bonus packed together  
the SCP-100. If you are a walker, runner, or a cyclist,  
carry it so you can be seen thousands of feet away  
(in clear weather). Clip it on your belt, wear it with the  
supplied armband, or secure it on your bicycle with  
the supplied mounting bracket.  
To power the personal safety light, you need two  
AAA batteries. For the best performance, we recom-  
mend alkaline batteries, such as RadioShack Cat.  
No. 23-555.  
Use a flat-blade screwdriver to carefully pry open the  
compartment cover. Insert the batteries into the com-  
partment, as indicated by the polarity symbols  
marked inside. Close the cover.

MAINTENANCE  
Your Optimus SCP-100 AM/FM Stereo Cassette  
Player is an example of superior design and crafts-  
manship. The following suggestions will help you  
care for the SCP-100 so you can enjoy it for years.  
• Keep the SCP-100 dry. If it gets wet, wipe it dry  
immediately.  
• Use and store the SCP-100 only in normal tem-  
perature environments.  
• Handle the SCP-100 gently and carefully. Don’t  
drop it.  
• Keep the SCP-100 away from dust and dirt.  
• Occasionally wipe the SCP-100 with a damp  
cloth to keep it looking new.  
Modifying or tampering with the SCP-100’s internal  
components can cause a malfunction and might in-  
validate its warranty and void your FCC authorization  
to operate it. If your SCP-100 is not performing as it  
should, take it to your local RadioShack store for as-  
sistance.

14-1248.fm Page 27 Friday, July 2, 1999 12:46 PM  
CLEANING THE TAPE-HANDLING  
PARTS  
Dirt, dust, or particles of the tape’s coating can accu-  
mulate on the tape head and other parts that the tape  
touches. This can reduce the SCP-100’s perfor-  
mance.  
Follow these steps to clean the tape-handling parts  
after about every 20 hours of tape player operation.  
1. Open the cassette compartment latch and door.  
2. Remove the batteries and disconnect any other  
power source.  
3. Press PLAY to expose the tape-handling parts.

FCC INFORMATION  
Your SCP-100 might cause TV or radio interference  
even when it is operating properly. To determine  
whether your SCP-100 is causing the interference,  
turn off your SCP-100. If the interference goes away,  
your SCP-100 is causing it. Try to eliminate the inter-  
ference by:  
• Moving your SCP-100 away from the receiver  
• Connecting your SCP-100 to an outlet that is on  
a different electrical circuit from the receiver  
• Contacting your local RadioShack store for help
