PORTABLE CART WARNING  
(symbol provided by RETAC)  
should follow the manufacturer’s instructions, and should use a mounting accessory rec-  
ommended by the manufacturer.  
8A. An appliance and cart combination should be moved with care. Quick stops, excessive  
force and uneven surfaces may cause the appliance and cart combination to overturn.  
9. VENTILATION  
Slots and openings in the cabinet and in the back or bottom are provided for ventilation,  
to ensure reliable operation of the product and to protect it from overheating. These  
openings must not be blocked or covered. The openings should never be blocked by  
placing the product on a bed, sofa, rug or other similar surface. This product should never be placed near  
or over a radiator or heat source. This product should not be placed in a built-in installation such as a  
bookcase or rack unless proper ventilation is provided or the manufacturer's instructions have been  
adhered to.  
10. POWER SOURCES  
This product should be operated only from the type of power source indicated on the marking label. If you  
are not sure of the type of power supply to your home, consult your appliance dealer or local power com-  
pany. For products intended to operate from battery power, or other sources, refer to the operating instruc-  
tions.  
11. GROUNDING OR POLARIZATION  
This product is equipped with a polarized alternating-current line plug (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 elec-  
trician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.  
12. POWER-CORD PROTECTION  
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.  
13. LIGHTNING  
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  
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 con-  
tact with them might be fatal.

16. OBJECT AND LIQUID ENTRY  
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 fire or electric shock. Never spill or spray any type of liquid on the product.  
17. OUTDOOR ANTENNA GROUNDING

INSTALLATION  
Unravel the AC cord and connect it to a conveniently  
located AC outlet having 120V and 60Hz only. The Clock  
Display will illuminate and "12:00" will appear in the  
window.  
NOTE: If the AC plug does not fit into a nonpolarized  
outlet, do not file or cut the wide blade. it is the user's  
responsibility to have an electrician replace the obsolete  
outlet.  
AC Outlet  
AC Plug  
If the AC cord is disconnected or if there is a power  
failure, this electronic clock is designed to continue operating internally (without showing  
the time on the Clock Display) with a 9 volt battery (not included). To install the battery,  
press and lift open the compartment cover. Connect the battery to the terminals of the  
battery snap inside the compartment (use of an alkaline battery is recommended) and  
snap the battery comaprtment cover back into place.  
Be sure to check the condition of the battery periodically by  
disconnecting the AC cord and connecting it again two or three  
minutes later. The preset times should continue operating. If  
the present time does not appear, it indicates the battery is  
dead or not connected properly. The 9 volt battery will keep the  
internal times accurately for approximately 30 minutes. If the  
power is restored after 30 minutes, the times may need to be  
reset.  
BATTERY PRECAUTIONS  
Follow these precautions when using a battery in this device:  
1. Use only the size and type of battery specified.  
2. Be sure to follow the correct polarity when installing the battery as indicated in the  
battery compartment. A reversed battery may cause damage to the device.  
3. If the device is not to be used for a long period of time, remove the battery to  
prevent damage or injury from possible battery leakage.  
4. Do not try to recharge a battery not intended to be recharged; it can overheat and  
rupture. (Follow battery manufacturer's directions.)

CARE AND MAINTENANCE  
Caring for Compact Discs  
• Treat the disc carefully. Handle the disc only  
by its edges. Never allow your fingers 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 dam-  
aged (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.  
Z
• This unit is designed to play only discs bearing the identification  
logo as shown here. Other discs may not conform to the CD stan-  
dard and may not play properly.  
• Discs should be stored in their cases after each use to avoid dam-  
age.  
• Do not expose discs to direct sunlight, high humidity, high temperatures, or  
dust, etc. Prolonged exposure or extreme temperatures can warp the disc.  
• Do not stick or write anything on either side of the disc. Sharp writing instru-  
ments 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.
