IMPORTANT SAFETY INSTRUCTIONS

Careful attention is devoted to quality standards in the manufacture of 
your cassette deck, and safety is a major factor in its design. However, 
safety is also your responsibility.

This section lists important information that will help you properly use 
and enjoy your cassette deck. 

Read all the included safety and operating 

instructions before using your cassette deck.

 Follow them closely, and 

retain them for future reference.

Heed Warnings

— Follow all warnings on the product and in the 

operating instructions.

Cleaning

— Unplug this product from the wall outlet before cleaning. 

Use only a damp cloth for cleaning. Do not use liquid or aerosol 
cleaners.

Attachments

— Do not use attachments/accessories not 

recommended by the product manufacturer, as they might create a 
hazard.

Water and Moisture

— Do not use this product near water (for 

example, near a bathtub, washbowl, kitchen sink, or laundry tub; in a 
wet basement; or near a swimming pool).

Accessories

— Do not place this product on an unstable cart, stand, 

tripod, bracket, or table. The product may fall, causing serious injury 
to a child or adult, and serious damage to the product. Use only with a 
cart, stand, tripod, bracket, or table recommended by the manufacturer 
or sold with the product. Follow the manufacturer's instructions for 
mounting, and use a recommended mounting accessory.

Carts

— Move the product on a cart carefully. Quick

stops, excessive force, and uneven surfaces may cause
the product/cart to overturn.

Ventilation

— Slots and openings in the cabinet provide ventilation, 

ensure reliable operation, and protect from overheating. Do not block 
or cover these openings, and do not place the product on a bed, sofa, 
rug, or other similar surface. Do not place the product in a built-in 
installation such as a bookcase or rack unless it provides proper 
ventilation as specified by the manufacturer.

Power Sources

— Operate this product using only the power source 

indicated on its marking label. If you are not sure of your home's power 
type, consult your product dealer or local power company.

Polarization

—  This product is equipped with a polarized AC line 

plug (a plug having one blade wider than the other). This plug will fit 
in the power outlet only one way. This is a safety feature. If you cannot 
insert the plug fully into the outlet, try reversing the plug. If the plug 
still doesn't fit, contact your electrician to replace your obsolete outlet. 
Do not defeat the safety purpose of the polarized plug. If you need an 
extension, use a polarized cord.

Power-Cord Protection

— Route power-supply cords so they are not 

likely to be walked on or pinched by items placed on or against them, 
paying particular attention to cords at plugs, convenience receptacles, 
and the point where they exit from the product.

Lightning

— For added protection for this product during 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.

Overloading

— Do not overload wall outlets, extension cords, or 

integral convenience receptacles, as this can result in a risk of fire or 
electric shock.

Objects and Liquids

— Never push objects of any kind into this 

product through openings, as they may touch dangerous voltage points 
or short out parts that could result in a fire or electric shock. Never spill 
liquid of any kind on the product.

Servicing

— Do not attempt to service this product yourself, as 

opening or removing covers may expose you to dangerous voltage or 
other hazards. Refer all servicing to qualified service personnel.

Damage Requiring Service

— Unplug this product from the wall 

outlet and refer servicing to qualified service personnel under the 
following conditions:

• When the power-supply cord or plug is damaged.

• If liquid has been spilled or objects have fallen into the product.

• If the product has been exposed to rain or water.

• If the product does not operate normally by following the operating

instructions. Adjust only those controls that are covered by the
operating instructions, as an improper adjustment of other controls
may result in damage and will often require extensive work by a
qualified technician to restore the product to normal operation.

• If the product has been dropped or damaged in any way.

• When the product exhibits a distinct change in performance.

Replacement Parts

— When replacement parts are required, be sure 

the service technician uses replacement parts specified by the 
manufacturer or having the same characteristics as the original part. 
Unauthorized substitutions may result in fire, electric shock, or other 
hazards.

Safety Check

— Upon completion of service or repairs to this 

product, ask the service technician to perform safety checks to 
determine that the product is in proper operating condition.

Wall or Ceiling Mount

— The product should be mounted to a wall 

or ceiling only as recommended by the manufacturer.

Heat

— The product should be situated away from heat sources such 

as radiators, heat registers, stoves, or other products (including
