adapter or by filing the wider blade to make it fit into your
outlet. If this plug does not fit into your outlet, you should
contact a qualified licensed electrician to replace your obsolete outlet.

CARE AND MAINTENANCE
SAFEGUARD AGAINST ACCIDENTAL
ERASURE
When a new recording is made, any program material
previously recorded is automatically erased and only the
new recording remains. To safeguard valuable
recordings from being erased accidentally, the cassette
and the deck are equipped with a special device.
On the back of the cassette there is an erase prevention
tab on each side. To prevent accidental erasing, break
out these tabs with a screwdriver. If only one side of the
tape is to be protected, break out the tab on the left side
with the side desired facing you.
To record on a tape in which the tab has been broken,
place a piece of adhesive tape over that area.
NOTE: When a tab is broken out, the record button
cannot be depressed.
CASSETTE TAPE RECOMMENDATIONS
Standard tape lengths have 15 (C-30), 30 (C-60) and 45 (C-90) minutes of recording time on each side.
Longer length tapes of 60 (C-120) minutes of recording time on each side are not recommended. Use only
high quality tapes. If a problem develops, check the unit first with another cassette to determine if the
problem is with the cassette, and not with the unit.
If there is any slack in the cassette, it should be removed before inserting the cassette. Place a pencil in one
of the hubs and rotate it clockwise until all slack is taken up.

only by its edges. Never allow your fingers to come in contact
with the shiny, unprinted side of the compact disc.
• Do not attach adhesive tape, stickers, etc. to the compact
disc label.
• Clean the compact disc periodically with a soft, lint-free, dry
cloth. Never use detergents or abrasive cleaners to clean
the compact disc. If necessary, use a CD cleaning kit.
• If a compact disc skips or gets stuck on a section of the compact disc, it is probably dirty or damaged (scratched).
• When cleaning the compact disc, wipe in straight lines from the center of the compact disc to the outer
edge of the compact disc. Never wipe in circular motions.
Z
COMPACT
• This unit is designed to play only compact discs bearing the identification logo as shown here.
Other compact discs may not conform to the CD standard and may not play properly.
• Compact discs should be stored in their cases after each use to avoid damage.
DIGITAL AUDIO
• Do not expose compact discs to direct sunlight, high humidity, high temperatures, or dust, etc. Prolonged
exposure or extreme temperatures can warp the compact disc.
• Do not stick or write anything on either side of the compact disc. Sharp writing instruments, or the ink may
damage the surface.
Cleaning the unit
• To prevent fire or shock hazard, disconnect your unit from the AC power source when cleaning.
• The finish on your unit may be cleaned with a dust cloth and cared for as other furniture. Use caution
when cleaning and wiping the plastic parts.
• Mild soap and a damp cloth may be used on the front panel.
• Periodic cleaning of the tape heads, capstan and pinch roller is necessary to maintain good sound
reproduction. Clean them after every 100 hours of use or less if playback has deteriorated. Use a cotton
swab moistened with head cleaning solution or isopropyl alcohol, then wipe dry with another swab.
NOTE: Never use metal objects on or near the tape heads. Do not allow any cleaning material to fall into the
tape assembly.
