ENERGY STAR® Program Information

As an ENERGY STAR® Partner, SHARP has determined that this product meets the ENERGY STAR® guidelines for energy efficiency.

ENERGY STAR® is a U.S. registered mark.

WHY PURCHASE ENERGY STAR® LABELED

PRODUCTS?

Many Electrical/Electronic Products use energy both when they are on and when they are off. Americans spend more than $3 billion a year on energy consumed by home electronic products when they are not in use. The new ENERGY STAR® labeled models will reduce that energy “leakage” by up to 75 percent. Ultimately, this will mean more t h a n $ 1 b i l l i o n a y e a r i n e n e r g y s a v i n g s f o r consumers.

The energy savings will help reduce the burning of fossil fuels and the related carbon dioxide pollution that contributes to global warming. If every American family replaced their electronic equipment with ENERGY STAR® labeled models, it would reduce air pollution equivalent to eliminating more than two million cars.

By using ENERGY STAR® labeled products, you will save money on your electric bills and use less energy.

That makes good economic sense and it’s good for our environment.

Condensation

Sudden temperature changes, storage or operation in an extremely humid environment may cause condensation inside the cabinet (CD pickup, etc.) or on the transmitter on the remote control.

Condensation can cause the unit to malfunction. If this happens, leave the power on with no disc in the unit until normal playback is possible (about 1 hour). Wipe off any condensation on the transmitter with a soft cloth before operating the unit.

If trouble occurs

When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction.

If such a problem occurs, do the following:

1Set the unit to the power stand-by mode and turn the power on again.

2If the unit is not restored in the previous operation, unplug and plug in the unit, and then turn the power on.

Note:

If neither operation above restores the unit, clear all the memory by resetting it.

Clearing all the memory (reset)

1Press the ON/STAND-BY button to enter the power stand-by mode.

2While pressing down the button and the VOLUME (-) button, press the ON/ STAND-BY button until "RESET" appears. (Can be done only from the unit.)

Caution:

This operation will erase all data stored in memory including clock, timer settings, tuner preset, and CD program.

Before transporting the unit

Carrying the unit with a CD inside can cause damage to the unit or the CD.

Please open the CD cover to check the CD compartment is empty before transportation. (Refer to page 19.)

Cleaning the cabinet

Periodically wipe the cabinet with a soft cloth and a diluted soap solution, then with a dry cloth.

Caution:

zDo not use chemicals for cleaning (gasoline, paint thinner, etc.). It may damage the cabinet finish.

zDo not apply oil to the inside of the unit. It may cause malfunctions.

Care of compact discs

Compact discs are fairly resistant to damage, however mistracking can occur due to an accumulation of dirt on the disc surface. Follow the guidelines below for maximum enjoyment from your CD collection and player.

zDo not write on either side of the disc, particularly the non-label side from which signals are read. Do not mark this surface.

zKeep your discs away from direct sunlight, heat, and excessive moisture.

zAlways hold the CDs by the edges. Fingerprints, dirt, or water on the CDs can cause noise or mistracking. If a CD is dirty or does not play properly, clean it with a soft, dry cloth, wiping straight out from the center, along the radius.
