Dear Customer:  
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:  
• Start your volume control at a low setting.  
• Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.  
Once you have established a comfortable sound level:  
• 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.  
This list of sound levels is included for your protection.

(a plug having one blade wider than the other). This plug will fit into the  
power outlet only one way. This is a safety feature. If you are unable to  
insert the plug fully into the outlet, try reversing the plug. If the plug  
should still fail to fit, contact your electrician to replace your obsolete  
outlet. Do not defeat the safety purpose of the polarized plug.  
12. POWER-CORD PROTECTION

technician to restore the product to its normal operation.  
e. If the product has been dropped or the cabinet has been damaged.  
Power-supply cords should be routed so that they are not likely to be  
walked on or pinched by items placed upon or against them, paying  
particular attention to cords at plugs, convenience receptacles, and the  
point where they exit from the appliance.

24. NOTE TO CATV SYSTEM INSTALLER  
To protect your product from a lightning storm, or when it is left  
unattended and unused for long periods of time, unplug it from the wall  
outlet and disconnect the antenna or cable system. This will prevent  
damage to the product due to lightning and power-line surges.  
14. POWER LINES  
This reminder is provided to call the CATV system installer's attention  
to Article 820-40 of the NEC that provides guidelines for proper  
grounding and, in particular, specifies that the cable ground shall be  
connected to the grounding system of the building, as close to the point  
of cable entry as practical.  
An outside antenna system should not be located in the vicinity of  
overhead power lines or other electric light or power circuits, or where it  
can fall into such power lines or circuits. When installing an outside  
antenna system, extreme care should be taken to keep from touching  
such power lines or circuits as contact with them might be fatal.

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 rst 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.

CARE AND MAINTENANCE (CONTINUED)  
Caring for Compact Discs  
• Treat the disc carefully. Handle the disc only by its edges.  
Never allow your ngers to come in contact with the shiny,  
unprinted side of the disc.  
• Do not attach adhesive tape, stickers, etc. to the disc label.  
• Clean the disc periodically with a soft, lint-free, dry cloth.  
Never use detergents or abrasive cleaners to clean the  
disc. If necessary, use a CD cleaning kit.  
• If a disc skips or gets stuck on a section of the disc, it is probably dirty or damaged (scratched).  
• When cleaning the disc, wipe in straight lines from the center of the disc to the outer edge of the disc.  
Never wipe in circular motions.
