standard AC outlet.
STANDBY
lights and AM 12:00 appears on the
display.
Warning: To prevent electric shock,
the power cord plug’s blades are polarized and fit a polarized AC outlet
only one way. If you have difficulty inserting the plug, do not force it. Turn it
over and reinsert it.
INSTALLING BATTERIES
1. Press in on the battery compartment cover and push in the direction of the arrow, and lift off the
cover.
illustration
2. Put two AA batteries in the compartment as indicated by the polarity symbols (+ and –) marked
inside.
3. Replace the cover.
In the System
In the Remote Control
Cautions:
The remote control requires two AAA
batteries (not supplied) for power. We
recommend alkaline batteries, such
as RadioShack Cat. No. 23-555 for
the best performance and longest life.
• Always use fresh batteries of the
required size and recommended
type.
• Never leave dead or weak batteries in the system or remote control. Batteries can leak chemicals
that can corrode the control.
• Do not mix old and new batteries,
different types of batteries (standard, alkaline, or rechargeable),
or rechargeable batteries of different capacities.
To retain any preset radio stations
during an AC power loss, install two
alkaline AA batteries (such as Cat.
No. 23-557) into the system’s battery
compartment.

1. Press the tab in the direction of
the arrow and lift off the battery
compartment cover.

13-1294.fm Page 9 Wednesday, July 14, 1999 7:01 PM
2. Install the batteries as indicated
by the polarity symbols (+ and -)
marked inside the compartment.
illustration
• Connecting headphones automatically disconnects the speakers.
• Your local RadioShack store
sells a wide selection of headphones.
Listening Safely
3. Replace the cover.
Caution: If you are not going to use
the remote control for a month or
more, remove its batteries. Batteries
can leak damaging chemicals.
You can use the remote control up to
a distance of about 20 feet from the
System 746. If the remote control
operates erratically or does not
work, replace both batteries.
USING HEADPHONES
You can use headphones (not supplied) to listen in privacy. Insert the
headphones’ 1/8-inch plug into the
jack.
To protect your hearing, follow these
guidelines when you use headphones.
• Do not listen at extremely high
volume levels. Extended highvolume listening can lead to permanent hearing loss.
• Set the volume to the lowest setting before you begin listening.
After you begin listening, adjust
the volume to a comfortable
level.
• 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.

CD CARE TIPS
Even though a compact disc is very
durable, treat the CD surface with
care. We recommend the following
precautions:
• Do not place anything but a CD in
the disc tray. This can damage the
drive mechanism.
• Do not write on either side of the
CD, particularly the non-label side
(signals are read from the non-label side).
• Do not store CDs in hightemperature, high-humidity locations. The CDs might warp.
• Keep CDs dry. A water drop can
act as a lens and affect the laser
beam’s focus.
• Always handle a CD by the edges
to avoid fingerprints and always
keep it in its protective case or
sleeve when not in use. Fingerprints and scratches on the CD’s
surface can prevent the laser
beam from correctly reading the
digital information. To clean the
CD surface, use a CD cleaner kit
(such as Cat. No. 42-225). If the
CD gets scratched, use Scratch ’n
Fix (RadioShack Cat. No. 42127).
• Press OPEN before or after programmed play.

pencil. If you do not remove excess slack, the tape might become tangled in the record/
playback mechanism. Avoid
touching the tape.
3. Insert the cassette tape into the
tape guides in the compartment
door, with its exposed tape edge
facing down, the side you want
play facing you, and its full reel

RECORDING ON A
CASSETTE TAPE
You can record from the CD player
or radio to a cassette tape.
Caution: If you use a cassette tape
with the erase-protection tabs removed, do not force down . This
can damage the recording mechanism. See “Preventing Accidental
Erasure” on Page 25.
Notes:
• Be sure the cassette’s eraseprotection tabs are in place (see
“Preventing Accidental Erasure”
on Page 25).
• Before you load a cassette tape
for recording, turn the cassette’s
hub with your finger or a pencil
to move the tape past its leader.
• The recording level is preset. EBASS and VOLUME have no effect on the recording level or
quality.
• Tape quality greatly affects the
quality of the recording. We recommend regular length (60- or
90-minute) cassette tapes. For
low-noise, wide-range recordings, use normal-bias tape.

tangling, press
as soon as
possible after the timer turns off.
Preventing Accidental
Erasure
Cassette tapes have two erase-protection tabs — one for each side. To
protect a recording from being accidentally recorded over or erased, use
a screwdriver to remove one or both of
the cassette tape’s erase-protection
tabs.
(Needs an illus - show

13-1294.fm Page 26 Wednesday, July 14, 1999 7:01 PM
If you want to record on a tape side after you have removed the eraseprotection tab, place a piece of strong
plastic tape over that side’s eraseprotection hole. Be sure you cover
only the hole originally covered by the
erase-protection tab.

Note: Removing the erase-protection
tabs does not prevent a bulk eraser
from erasing a cassette tape.

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, fastforward 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 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 System 746 Micro Stereo Component System is an example of superior design and craftsmanship. The following suggestions will help you care for
the system so you can enjoy it for years.
Keep the system dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Handle the system gently and carefully. Dropping it can damage circuit boards and cases and can cause the system to work improperly.
Use only fresh batteries of the required size and type. Batteries can
leak chemicals that damage your system’s electronic parts.
Use and store the system only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices,
damage batteries, and distort or melt plastic parts.
Keep the system away from dust and dirt, which can cause premature wear of parts.
Wipe the system with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the system.
Modifying or tampering with the system’s internal components can cause a malfunction and might invalidate your system’s warranty and void your FCC authorization to operate it. If your system is not performing as it should, take it to your local
RadioShack store for assistance.

CLEANING THE TAPEHANDLING PARTS
Dirt, dust or particles of the tape’s
coating can accumulate on the tape
heads and other parts that the tape
touches. This can greatly reduce the
cassette player’s performance. To
prevent noise and poor highfrequency response, clean the cassette player’s tape-handling parts after
every 20 hours of use. Your local RadioShack store sells a wide selection
of cassette deck cleaning supplies.
1. Turn off the system, then unplug
its power cord.
2. Press
. The cassette compartment door opens.
5. When you finish cleaning, press
to release the play mechanism, then close the cassette
compartment door and reconnect
power.
RESETTING THE
SYSTEM
If the System 746 is not working properly, reset it to delete all programmed
play sequences, memory tuning settings, timer sequences, and the time.
To reset the system, insert a pointed
object (such as a straightened paper
clip) into the RESET hole on the back
of the system.
3. Press
on the deck to expose
the tape-handling parts.
4. Use a cotton swab dipped in denatured alcohol or tape head
cleaning solution to gently clean
the record/playback head, pinch
roller, capstan, tape guides, and
erase head.
