tion of the arrow, and lift off the

display.
illustration
Warning: To prevent electric shock,
the power cord plug’s blades are po-
larized and fit a polarized AC outlet
only one way. If you have difficulty in-
serting the plug, do not force it. Turn it
over and reinsert it.
2. Put two AA batteries in the com-
partment as indicated by the po-
larity symbols (+ and –) marked
inside.
3. Replace the cover.
INSTALLING BATTERIES
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 batter-
ies in the system or remote con-
trol. Batteries can leak chemicals
that can corrode the control.
1. Press the tab in the direction of
the arrow and lift off the battery
compartment cover.
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable),
or rechargeable batteries of differ-
ent capacities.
illustration
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.

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.
• Connecting headphones auto-
matically disconnects the speak-
ers.
• Your local RadioShack store
sells a wide selection of head-
phones.
illustration
Listening Safely
To protect your hearing, follow these
guidelines when you use head-
phones.
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.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
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.
• Set the volume to the lowest set-
ting 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.
USING HEADPHONES
You can use headphones (not sup-
plied) to listen in privacy. Insert the
headphones’ 1/8-inch plug into the
jack.

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.
To replace a programmed track,
Note:
press PROGRAM/MEMORY (or PROG
on the remote control) until the posi-
tion number of the track you want to
replace appears. Then repeat Steps 3
and 4 to select and store the new
track.
• Do not write on either side of the
CD, particularly the non-label side
(signals are read from the non-la-
bel side).
• Do not store CDs in high-
temperature, high-humidity loca-
tions. The CDs might warp.
Reviewing the Programmed
Sequence
• Keep CDs dry. A water drop can
act as a lens and affect the laser
beam’s focus.
While play is stopped, repeatedly
press PROGRAM/MEMORY (or PROG
on the remote control) to review the
programmed sequence.
• Always handle a CD by the edges
to avoid fingerprints and always
keep it in its protective case or
sleeve when not in use. Finger-
prints 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. 42-
127).
Erasing the Programmed
Sequence
You can do either of the following to
erase a programmed sequence:
• Press PROGRAM/MEMORY (or
PROG on the remote control) then
STOP
before or after pro-
grammed play.
• Press OPEN before or after pro-
grammed play.

CASSETTE DECK OPERATION
The system has one cassette deck
for cassette tape playback and re-
cording. The deck has a full-release
auto-stop system to protect tapes
and prevent pinch roller damage.
When a tape reaches the end of a
side, the tape mechanism automati-
cally stops and releases 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
to the left.
4. Close the compartment door.

Timer Recording
TAPE CARE TIPS
You can set the system to automati-
cally turn on, record from a selected
audio source onto a cassette tape,
then turn off at the time you set.
Erasing a Cassette Tape
To erase a previously recorded sec-
tion of a tape, simply record over it. To
erase the entire cassette tape, let the
tape record to the end with no source
playing.
1. Follow Steps 1–5 in “Setting a
Wake-Up Time” on Page 12 to set
the start and end times and select
the source you want to record
from.
You can quickly erase both sides of a
cassette tape using a bulk tape eraser
(such as Cat. No. 44-232, not sup-
plied).
2. Load a blank cassette tape, or
one you want to record over.
3. Press then (Record).
4. Press TIMER to turn on the timer.
Preventing Accidental
Erasure
Cassette tapes have two erase-pro-
tection tabs — one for each side. To
protect a recording from being acci-
dentally recorded over or erased, use
a screwdriver to remove one or both of
the cassette tape’s erase-protection
tabs.

5. Release . At the preset start
time, the system turns on and

To turn off the timer before it automat-
ically turns off, press TIMER until

If you want to record on a tape side af-
ter you have removed the erase-
protection tab, place a piece of strong
plastic tape over that side’s erase-
protection hole. Be sure you cover
only the hole originally covered by the
erase-protection tab.
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 completely
rewind it. Then loosen the tape reels
by gently tapping each side of the cas-
sette’s outer shell on a flat surface.
illustration
Note: Removing the erase-protection
tabs does not prevent a bulk eraser
from erasing a cassette tape.
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 su-
perior 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 cir-
cuit 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 prema-
ture 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 deter-
gents to clean the system.
Modifying or tampering with the system’s internal components can cause a mal-
function and might invalidate your system’s warranty and void your FCC authoriza-
tion to operate it. If your system is not performing as it should, take it to your local
RadioShack store for assistance.

5. When you finish cleaning, press
to release the play mecha-
nism, then close the cassette
compartment door and reconnect
power.
CLEANING THE TAPE-
HANDLING 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 high-
frequency response, clean the cas-
sette player’s tape-handling parts after
every 20 hours of use. Your local Ra-
dioShack store sells a wide selection
of cassette deck cleaning supplies.
RESETTING THE
SYSTEM
If the System 746 is not working prop-
erly, reset it to delete all programmed
play sequences, memory tuning set-
tings, timer sequences, and the time.
1. Turn off the system, then unplug
its power cord.
To reset the system, insert a pointed
object (such as a straightened paper
RESET
clip) into the hole on the back
of the system.
2. Press
. The cassette com-
partment door opens.
3. Press
on the deck to expose
the tape-handling parts.
4. Use a cotton swab dipped in de-
natured alcohol or tape head
cleaning solution to gently clean
the record/playback head, pinch
roller, capstan, tape guides, and
erase head.
