ENERGYSTAR® Program Information

As an ENERGYSTAR® Partner, SHARP has determined that this product meets theENERGYSTAR® guidelines for energy efficiency.

ENERGYSTAR® is a U.S. registered mark.

WHY PURCHASE ENERGYSTAR® 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 ENERGYSTAR® 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 ENERGYSTAR® labeled models, it would reduce air pollution equivalent to eliminating more than two million cars.

By using ENERGYSTAR® 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.

4" (10 cm)

z Use the unit on a firm, level surface free from vibration.

z Keep the unit away from direct sunlight, strong magnetic fields, excessive dust, humidity and electronic/ electrical equipment (home computers, facsimiles, etc.) which generate electrical noise.

zDo not place anything on top of the unit.

zDo not expose the unit to moisture, to temperatures higher than 140°F (60°C) or to extremely low temperatures.

zIf your system does not work properly, disconnect the AC power cord from the AC outlet. Plug the AC power cord back in, and then turn on your system.

zIn case of an electrical storm, unplug the unit for safe-

ty.

zHold the AC power plug by the head when removing it from the AC outlet, as pulling the cord can damage in-

ternal wires.

zDo not remove the outer cover, as this may result in electric shock. Refer internal service to your lo-

cal SHARP service facility.

z This unit should only be used within the range of 41°F - 95°F (5°C - 35°C).
