PHONES
jack on the front of the Sys-
tem 734.
3. Replace the cover.
Note: Connecting headphones auto-
matically disconnects the System
734’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
meters), from an angle of up to
60° in front of the System 734. If it
does not operate properly within
this range, replace the batteries.
To protect your hearing, follow these
guidelines when you use headphones.
• 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-vol-
ume listening can lead to perma-
nent 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 1/4-inch plug ste-
reo headphones (not supplied) to the
System 734. Your local Radio Shack
store sells a wide selection of stereo
headphones.

Cautions:
CD AND CD CHANGER
CARE TIPS
• To avoid damaging the CD
changer, do not place anything
but a CD in the CD drawer.
Although a CD is very durable, you
should handle it with care. We recom-
mend the following precautions.
• Remove any loaded CDs from the
CD changer before moving the
System 734 to prevent damaging
the CDs.
• Keep the CD in its protective case
or sleeve when you are not play-
ing it.
• Moving the CD changer suddenly
from a cold place to a warmer one
can cause moisture to form on the
pickup lens and disrupt operation.
If this happens, wait about one
hour before playing a CD.
• Keep the CD clean. Your local
Radio Shack store sells a suitable
CD cleaner kit.
• Keep the CD dry. A drop of mois-
ture 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.
• Do not write on either side of a
CD, especially the non-label side.
• Handle the CD by its edges to
avoid fingerprints and surface
scratches, which can prevent the
laser from accurately reading 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-tempera-
ture, high-humidity locations.
If the System 734 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 malfunction.

CASSETTE DECK OPERATION
The System 734 has a dual cassette
LOADING A TAPE
deck system which lets you automati-
cally play one side of two cassette
tapes consecutively, record from the
CD changer, record one cassette tape
onto another, and more.
1. Press STOP/EJECT on the desired
tape deck (TAPE 1 or TAPE 2) to
open the cassette compartment
door.
Note: TAPE 1 both plays back
and records. TAPE 2 only plays
prerecorded cassette tapes.
Notes:
• The remote control does not oper-
ate the System 734’s cassette
deck.
2. Insert the cassette tape with the
exposed tape edge facing down,
the side you want to play facing
you, and the full reel to the left.
• The System 734’s Automatic
Level Control (ALC) feature auto-
matically adjusts the recording
level. The VOLUME, E-BASS, and
ROCK, POP, or CLASSIC settings
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 mechanism. For
low-noise, wide-range recordings,
use normal-bias tape.
3. Close the door.
PLAYING A TAPE
1. Repeatedly press FUNCTION until
appears next to TAPE on the
display.
• 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 touch-
ing the tape with your fingers.)
• Before recording, be sure the cas-
sette tape’s erase-protection tabs
are in place. See “Preventing
Accidental Erasure.”

TAPE TIPS
Erasing a Cassette Tape

record over the previous recording. To
erase the entire cassette tape, select a

tion tab does not prevent a bulk eraser
from erasing a cassette tape.
CD
function with no audio (such as
with
no CD playing) and let the tape record
to the end.
Restoring Tape Tension and
Sound Quality
Note: The tape you are recording over
must be a normal bias-type tape.
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 quickly erase a tape, you might pre-
fer to use a bulk tape eraser (available
at your local Radio Shack store).
To restore the sound quality, fast-for-
ward the tape from the beginning to the
end of one side, then completely re-
winding it. Then loosen the tape reels
by gently tapping each side of the cas-
sette’s outer shell on a flat surface.
Preventing Accidental
Erasure
Cassette tapes have two erase-protec-
tion tabs — one for each side.
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.
To protect a recording from being acci-
dentally recorded over or erased,
break off that side’s plastic tab with a
screwdriver.

CARE AND MAINTENANCE
Your Optimus System 734 Mini Stereo Component System is an example of supe-
rior design and craftsmanship. The following suggestions will help you care for the
System 734 so you can enjoy it for years.
Keep the System 734 dry. If it gets wet, wipe it dry immediately. Liq-
uids contain minerals that can corrode the electronic circuits
Handle the System 734 gently and carefully. Dropping it can damage
the circuit boards and can cause the System 734 to work improperly.
Use and store the System 734 only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic de-
vices, damage batteries, and distort or melt plastic parts.
Keep the System 734 away from dust and dirt, which can cause pre-
mature wear of parts.
Wipe the System 734 with a damp cloth occasionally to keep it look-
