This system is equipped with non-skid rubber ‘feet’ to prevent the product from moving when you
operate the controls. These ‘feet’ are made from non-migrating rubber material specially
formulated to avoid leaving any marks or stains on your furniture. However certain types of oil
based furniture polishes, wood preservatives, or cleaning sprays may cause the rubber ‘feet’ to
soften, and leave marks or a rubber residue on the furniture.
To prevent any damage to your furniture we strongly recommend that you purchase small
self-adhesive felt pads, available at hardware stores and home improvement centers
everywhere and apply these pads to the bottom of the rubber ‘feet’ before you place the product
on fine wooden furniture.

DEAR STUDEBAKER ® CUSTOMER

CONTENTS OF YOUR PRODUCT
Selecting fine audio equipment such as the unit you've just purchased is only the start of your
musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries Association's Consumer
Electronics Group want you to get the most out of your equipment by playing it at a safe level. One
that lets the sound come through loud and clear without annoying blaring or distortion and, most
importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time your
hearing "comfort level" adapts to higher volumes of sound. So what sounds "normal" can actually be
loud and harmful to your hearing. Guard against this by setting your equipment at a safe level
BEFORE your hearing adapts.
To establish a safe level:
OStart your volume control at a low setting.
OSlowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established a comfortable sound level:
OSet the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we
want you listening for a lifetime.
We Want You Listening For a Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing
damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic
Industries Association's Consumer Electronics Group recommend you avoid prolonged exposure to
excessive noise.
Customer's Record:
The serial number of this product is found on its back cover. You should note the serial number of
this unit in the space provided as a permanent record of your purchase to aid in identification in the
event of theft of loss.

CASSETTE CARE
Two common causes of trouble experienced when using cassettes are:
1) Tape Jamming – Leading to uneven speed in playback, and
2) Tape Tangling – Where the tape wraps itself around ital parts of
the mechanism.
To reduce the likelihood of these problems occurring, the following precautions should be
observed:
• Check that there are no loose layers of tape visible through the cassette center window (see
Fig. 1). Take up any loose layers, using a pencil or hexagonal barrelled ballpoint pen, before
inserting the cassette into the machine (see Fig.2).
• If the cassette feels tight while performing operation shown (see
Fig.2), the tape may be jamming due to ridges formed in the winding
of the tape (visible through the center window). These may be
removed, in most cases, by fast winding of the cassette from one
end to the other and back again.
• Use only well-known brands of tape. Avoid use of C-120 cassettes.
Furthermore, do not expose cassettes to direct sunlight, dust or oil, and do not touch the tape
surfaces.
16
CARE AND MAINTENANCE
1. Do not subject the unit to excessive force, shock, dust or extreme temperature.
2. Do not tamper the internal components of the unit.
3. Clean your unit with a dry cloth. Solvent or detergent should never be used.
4. Avoid leaving your unit in direct sunlight or in hot, humid or dusty places.
5. Keep your unit away from heating appliances and sources of electrical noise such as
fluorescent lamps or motors.
ABOUT CASSETTE TAPES
Whenever you record on a cassette any previously recorded material is erased as the new
material is recorded. To prevent you from accidentally erasing material which you wish to save,
blank cassettes are equipped with erase prevention tabs for each side of the tape. If the erase
prevention tab for side A is removed, you cannot accidentally record on side A. The Record
button cannot be depressed if the erase prevention tab on the cassette has been removed.
To prevent accidental erasing on side A of a cassette use a small screw driver or similar tool to
break off the erase prevention tab for side A. This prevents the record button form locking.

OClean the disc periodically with soft, lint-free, dry cloth. Never use detergents or adhesive
cleaners to clean the disc. If necessary, use a CD cleaning kit.
OIf disc skips or gets stuck on a section of the disc, it is probably dirty or damaged (scratched).

disc. Never wipe in circular motions.
OTo remove a disc from its storage case, press down on the center of the case and lift the disc
outs, holding it carefully by the edges.
OFingerprints and dust should be carefully wiped off the disc's recorded surface with a soft
cloth. Unlike conventional records. compact discs have no grooves to collect dust and
microscopic debris so gently wiping with a soft cloth should remove most particles.
CLEANING THE UNIT
OTo prevent fire or shock hazard, disconnect your unit from the AC power source when
cleaning.
OThe finish on the unit may be cleaned with a dust cloth and cared for as other furniture, Use
caution when cleaning and wiping the plastic parts.
OIf the cabinet becomes dusty wipe it with a soft dry dust cloth. Do not use any wax or polish
sprays on the cabinet.
OIf the front panel becomes dirty or smudged with fingerprints it may be cleaned with a soft
cloth slightly dampened with a mild soap and water solution. Never use abrasive cloths or
polishes as these will damage the finish of your unit.
CAUTION: Never allow any water or other liquids to get inside the unit while cleaning.
