Sony HT-SF470 Operating Instructions - Page 66

On placement • Place the receiver in a location with adequate ventilation to prevent heat buildup and prolong the life of the receiver. • Do not place the receiver near heat sources, or in a place subject to direct sunlight, excessive dust, or mechanical shock. • Do not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions. • Do not place the receiver near equipment such as a TV, VCR, or tape deck. If the receiver is being used in combination with a TV, VCR, or tape deck, and is placed too close to that equipment, noise may result, and picture quality may suffer. This is especially likely when using an indoor antenna. Therefore, we recommend using an outdoor antenna. • Use caution when placing the receiver or speakers on surfaces that have been specially treated (with wax, oil, polish, etc.) as staining or discoloration of the surface may result. On operation Before connecting other components, be sure to turn off and unplug the receiver. If you encounter color irregularity on a nearby TV screen The center speaker is magnetically shielded to allow it to be installed near a TV set. However, color irregularities may still be observed on certain types of TV sets. As the front speakers, surround speakers and subwoofer are not magnetically shielded, we recommend that you place them slightly further away from TV set (page 15). If color irregularity is observed... Turn off the TV set, then turn it on again after 15 to 30 minutes. If color irregularity is observed again... Place the speaker further away from the TV set. If howling occurs Reposition the speakers or turn down the volume on the receiver. On cleaning • Clean the cabinet, panel, and controls with a soft dry cloth. Do not use any type of abrasive pad, scouring powder, scrubbing brush or sponge. • If it is stained with oil or fingerprints, breath on the surface and wipe it with soft dry cloth. On S-AIR function • As the S-AIR product(s) transmits sound by radio waves, sound may skip when radio waves are obstructed. This is a characteristic of radio waves and is not malfunction. • As the S-AIR product(s) transmits sound by radio waves, equipment that generates electromagnetic energy, such as a microwave oven, may interfere with sound transmission. • As the S-AIR product(s) uses the radio waves that share the same frequency as other wireless systems, such as wireless LAN or Bluetooth devices, interference or poor transmission may result. In this case, take the following steps: - Avoid placing the S-AIR product(s) near other wireless systems. - Avoid using the S-AIR product(s) and the other wireless systems at the same time. - The transmission may be improved by changing the transmission channel (frequency) of the other wireless system(s). For details, refer to the operating instructions of the other wireless system(s). 66US
