PREPARATION  
INSTALLING BATTERIES  
Your SCR-100 requires two AA batteries (not sup-  
plied) for power. For the best performance and long-  
est life, we recommend RadioShack alkaline  
batteries.  
Cautions:  
• Use only fresh batteries of the required size and  
recommended 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. Slide the battery compartment cover in the direc-  
tion of the arrow to open it.  
5
 
14-1252.fm Page 6 Thursday, October 28, 1999 3:27 PM  
2. Place the batteries in the compartment as indi-  
cated by the polarity symbols (+ and –) marked  
inside  
3. Replace the cover.  
When RECORD/BATT does not light steadily during  
play, replace the batteries.  
Warning:  
Dispose of old batteries promptly and  
properly. Do not bury or burn them.  
Caution:  
If you do not plan to use the SCR-100 with  
batteries for two weeks or more, remove the batter-  
ies. Batteries can leak chemicals that can destroy  
electronic parts.  
USING AC POWER  
You can power the SCR-100 using a 3V, 300-mA AC  
adapter and a size H Adaptaplug® (neither supplied).  
Both are available at your local RadioShack store.  
6
 
14-1252.fm Page 7 Thursday, October 28, 1999 3:27 PM  
Cautions:  
You must use a Class 2 power source  
that supplies 3V AC and delivers at  
least 300 mA. Its center tip must be set  
!
to positive and its plug must fit the SCR-100's  
DC 3V  
jack. Using an adapter that does not  
meet these specifications could damage the  
SCR-100 or the adapter.  
• Always connect the AC adapter to the SCR-100  
before you connect it to AC power. When you  
finish, disconnect the adapter from AC power  
before you disconnect it from the SCR-100.  
Follow these steps to power the SCR-100 from stan-  
dard AC power.  
1. Set the adapter’s voltage switch to 3V.  
7
 
14-1252.fm Page 8 Thursday, October 28, 1999 3:27 PM  
2. Insert the Adaptaplug into the cord so it reads  
TIP +.  
3. Insert the adapter’s barrel plug into the SCR-  
DC 3V  
100’s  
jack.  
4. Plug the adapter into a standard AC outlet.  
USING DC POWER  
You can power the SCR-100 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 sup-  
plies 3V DC and delivers at least 300  
mA. Its center tip must be set to posi-  
!
DC 3V  
tive and its plug must fit the SCR-100's  
jack. Using an adapter that does not meet these

14-1252.fm Page 9 Thursday, October 28, 1999 3:27 PM  
specifications could damage the SCR-100 or the  
adapter.  
• Always connect the DC adapter to the SCR-100  
before you connect it to the power source. When  
you finish, disconnect the adapter from the pow-  
er source before you disconnect it from the  
SCR-100.  
Follow these steps to power the SCR-100 from DC  
power.  
1. Set the adapter’s voltage switch to 3V.  
2. Insert the Adaptaplug into the cord so it reads  
TIP +.  
3. Insert the adapter’s barrel plug into the SCR-  
DC 3V  
100’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 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.

14-1252.fm Page 12 Thursday, October 28, 1999 3:27 PM  
Traffic Safety  
Do not wear headphones while operating a motor ve-  
hicle or riding a bicycle. This can create a traffic haz-  
ard and could be illegal in some areas.  
Even though some headphones let you hear some  
outside sounds when listening at normal volume lev-  
els, they still can present a traffic hazard.

OPERATION  
LOADING A CASSETTE TAPE  
Follow these steps to load a cassette to record or  
play.  
1. Take up any slack in the  
cassette tape by turning  
the hub with a pencil to  
prevent the tape from  
becoming tangled in the  
tape mechanism. Do not  
touch the tape.  
2. Open the cassette compartment door by lifting it  
at the notch.  
3. Insert a cassette tape  
into the door guides so  
the cassette’s open  
edge faces out, the  
side you want to use  
faces up, and the full  
reel is to the left.

Using External Stereo Microphones  
You can record in stereo using two mono micro-  
phones. This lets you place each microphone for the  
best response and stereo separation. Your local Ra-  
dioShack store carries a wide selection of suitable  
microphones.  
1. Place two mono microphones equidistant apart  
and equidistant from the sound source.

PLAYING A TAPE  
1. For mono playback, simply listen to the built-in  
speaker. The SCR-100 combines the left and  
right channels. For stereo playback, connect the  
SCR-100 to a pair of stereo headphones or an  
amplified speaker system (see “Connecting  
Headphones/Speakers” on Page 10).  
Note:  
Connecting headphones or an amplified  
speaker system disconnects the built-in speak-  
ers.  
2. Take up any slack in the tape by turning the cas-  
sette’s hub with a pencil. Do not touch the  
exposed tape.  
3. Lift the cassette compartment door and insert  
the cassette tape into the cassette guides with  
its open edge facing up. Be sure the full reel is to  
the right and the side you want to listen to faces  
the door.  
TAPE SPEED  
4. Set  
to the same speed you used  
when you recorded the tape.

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 com-  
pletely rewind it. Then loosen the tape reels by gently  
tapping each side of the cassette’s outer shell on a  
flat surface.  
19  
 
14-1252.fm Page 20 Thursday, October 28, 1999 3:27 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.  
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 SCR-100’s perfor-  
mance.  
After every 20 hours of tape player operation, follow  
these steps to clean the tape-handling parts or use a  
cassette deck cleaning kit available from your local  
RadioShack store.  
1. Remove the batteries and disconnect any other  
power source.  
2. Open the cassette compartment door and press  
PLAY  
to expose the tape-handling parts.  
20  
 
14-1252.fm Page 21 Thursday, October 28, 1999 3:27 PM  
3. Use a cotton swab dipped in denatured alcohol  
or tape head cleaning solution to clean the tape  
guides, record head, play head, pinch roller, and  
capstan.  
Capstan

CARE
