PREPARATION  
Important: Complete all other con-  
nections to the System 730 before  
you connect it to power.  
Note: You can use the set of termi-  
nals marked SURROUND SPEAKER  
to connect surround sound speakers  
(not supplied) to your System 730.  
Your local Radio Shack sells a wide  
selection of surround sound speak-  
ers.  
CONNECTING THE  
SPEAKERS  
1. Press open the pair of terminal  
Speaker Placement  
+
tabs marked MAIN SPEAKERS/  
R – on the back of the System  
730, then insert the right  
speaker’s red wire into the red  
(+) terminal and its black wire  
into the black (–) terminal. Then  
release the tabs.  
For the best stereo effect, place the  
speakers so the distance between  
them is the same as the distance be-  
tween the listening area and the point  
halfway between the speakers. You  
might want to experiment with sever-  
al locations to find the best one.  
Notes:  
• If the you place the speakers far  
apart, you can improve the ste-  
reo effect by angling the speak-  
ers toward you.  
To increase the bass sound,  
place the speakers in the corner  
of the room, against the wall or  
directly on the floor.  
Caution: To avoid damaging  
your system and speakers,  
never let the speaker wire’s bare  
ends touch each other.  
To decrease the bass sound,  
move the speakers slightly away  
from the corner, increase the  
distance between them, and/or  
raise them 6 to 8 inches off the  
floor. You can purchase speaker  
stands at your local Radio  
Shack store.  
2. Repeat Step 1 to connect the left  
speaker’s wires to the terminals  
+
marked MAIN SPEAKERS/ L –.

Note: Connecting headphones auto-  
matically disconnects the System  
730’s speakers.  
Notes:  
• If you will not be using the  
remote control for a month or  
more, remove the batteries.  
Listening Safely  
• You can use the remote control  
up to a distance of about 20 feet  
(6.1 meters) in front of the Sys-  
tem 730. If it does not operate  
properly within this distance,  
replace the batteries.  
To protect your hearing, follow these  
guidelines when you use head-  
phones.  
• Set the volume to the lowest set-  
ting before you begin listening.  
After you begin listening, adjust  
the volume to a comfortable  
level.  
Warning: Always dispose of old bat-  
teries promptly and properly.  
• Do not listen at extremely high  
volume levels. Extended high-  
volume listening can lead to per-  
manent hearing loss.  
CONNECTING  
HEADPHONES  
• 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.  
To listen without disturbing others,  
you can connect a pair of stereo  
1
headphones with a /8-inch plug (not  
supplied) to the System 730. Your lo-  
cal Radio Shack store sells a wide  
selection of stereo headphones.

CARE TIPS  
To erase an entire programmed se-  
quence, while play is stopped, press  
Although a CD is very durable, you  
should handle it with care. We rec-  
ommend the following precautions.  
and hold STOP  
, or CD  
on the  
remote control, for at least 2 sec-  
onds. MEMORY disappears from the  
display.  
• Keep the CD in its protective  
case or sleeve when you are not  
playing it.  
• Keep the CD clean. Your local  
Radio Shack store sells a suit-  
able CD cleaner kit.  
• Keep the CD dry. A drop of  
moisture can act as a lens and  
affect the laser beam’s focus. If  
it gets wet, wipe the CD with a  
soft, dry cloth before playing it.  
Notes:  
• If you remove a CD, the CD  
changer automatically skips that  
disc’s tracks in the sequence.  
• Do not write on either side of a  
CD, especially the non-label  
side.  
• When power is disconnected or  
interrupted for 50 hours or more,  
any programmed sequence is  
entirely erased.  
• Handle the CD by its edges to  
avoid fingerprints and surface  
scratches, which can prevent  
the laser from accurately read-  
ing the CD. If the CD gets  
scratched, use Scratch ‘n’ Fix  
(Radio Shack Cat. No. 42-127)  
to keep the CD from skipping  
during play.  
• Do not store CDs in high-tem-  
perature, high-humidity loca-  
tions.  
23  
 
13-1277.fm Page 24 Wednesday, July 14, 1999 4:11 PM  
If the System 730 is subjected to a  
sudden shock or jolt during play, the  
CD’s rotation speed might suddenly  
change, and the music might be  
briefly interrupted. This is not a mal-  
function.  
Cautions:  
To avoid damaging the CD  
changer, do not place anything  
but a CD in the CD drawer.  
• Remove any loaded CDs from  
the CD changer before moving  
the System 730 to prevent dam-  
aging the CDs.  
• Moving the CD changer sud-  
denly from a cold place to a  
warmer one can cause moisture  
to form on the pickup lens and  
disrupt operation. If this hap-  
pens, wait about 2 hours before  
playing a CD.

CASSETTE DECK OPERATION  
The System 730 has a dual cassette  
deck system which lets you automat-  
ically play two cassette tapes con-  
secutively, record from the CD  
changer, record one cassette tape  
onto another, and more.  
• Before recording, be sure the  
cassette tape’s erase-protection  
tabs are in place. See “Prevent-  
ing Accidental Erasure.”  
LOADING A TAPE  
Notes:  
1. Press STOP/EJECT on the  
desired tape deck (TAPE 1 or  
TAPE 2) to open the cassette  
compartment door.  
• The remote control does not  
operate the System 730’s cas-  
sette deck.  
• The System 730’s Automatic  
Level Control (ALC) feature  
automatically adjusts the record-  
ing level. The settings of VOL-  
UME, X-BASS, and ROCK, POP,  
or CLASSIC have no effect on  
the recording.  
Tape quality greatly affects the  
quality of the recording. We rec-  
ommend regular length (60- or  
90-minute) cassette tapes. We  
do not recommend long-play  
cassette tapes, such as C-120s,  
because they are thin and can  
easily tangle in the cassette  
Note: TAPE 1 only plays prere-  
corded cassette tapes. TAPE 2  
both plays back and records.

mechanism.  
For  
low-noise,  
wide-range recordings, use nor-  
mal-bias tape.  
• Before you load a cassette tape  
for recording, turn the cassette’s  
hub with your finger or a pencil  
to take up any slack and move  
the tape past its leader. (Avoid  
touching the tape with your fin-  
gers.)

TAPE TIPS  
Erasing a Cassette Tape  
To record over a cassette tape, sim-  
ply record over the previous record-  
ing.  
: Removing the erase-pro-  
Caution  
tection tab does not prevent a bulk  
eraser from erasing a cassette tape.  
: The tape you are recording  
Note  
over must be a normal bias-type  
tape.  
Restoring Tape Tension and  
Sound Quality  
To quickly erase a tape, you might  
prefer to use a bulk tape eraser, such  
as Radio Shack Cat. No. 44-232.  
After you play a cassette tape sever-  
al times, the tape might become  
tightly wound on the reels. This can  
cause playback sound quality to de-  
teriorate.  
Preventing Accidental  
Erasure  
To restore the sound quality, fast-for-  
ward 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 sur-  
face.  
Cassette tapes have two erase-pro-  
tection tabs — one for each side.  
To protect a recording from being ac-  
cidentally recorded over or erased,  
break off that side’s plastic tab with a  
screwdriver.  
: Be careful not to damage  
Caution  
the cassette when tapping it. Do not  
touch the exposed tape or allow any  
sharp objects near the cassette.

THE FCC WANTS YOU  
TO KNOW  
CLEANING THE TAPE-  
HANDLING PARTS  
This stereo system complies with the  
limits for a Class B digital device as  
specified in Part 15 of FCC Rules.  
These limits provide reasonable pro-  
tection against radio and TV interfer-  
ence in a residential area. However,  
your stereo system might cause TV  
or radio interference even when it is  
operating properly. To eliminate in-  
terference, you can try one or more  
of the following corrective measures:  
Dirt, dust or particles of a cassette  
tape’s coating can accumulate on the  
cassette deck tape heads, and other  
parts that the tape touches. This can  
greatly reduce the performance of  
the cassette decks. Use the following  
cleaning procedure for each deck af-  
ter every 20 hours of tape player op-  
eration.  
1. Be sure the system is off, then  
disconnect power.  
• Reorient or relocate the receiv-  
ing antenna  
2. Open the cassette compartment  
door on each deck.  
• Increase the distance between  
the stereo system and the radio  
or TV  
PLAY  
3. Press  
to expose the tape-  
handling parts.  
• Use outlets on different electrical  
circuits for the stereo system  
and the radio or TV  
4. Use a cotton swab dipped in  
denatured alcohol or tape head  
cleaning solution to clean each  
deck’s record or play head,  
pinch roller, capstan and erase  
head.  
Consult your local Radio Shack store  
if the problem still exists.  
You must use shielded interface ca-  
bles with this stereo system.  
5. When you finish cleaning, close  
each deck’s cassette compart-  
ment door and reconnect power.  
Your local Radio Shack store sells a  
complete line of cassette deck clean-  
ing supplies.
