RISK OF ELECTRIC SHOCK DO NOT OPEN The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] When using this kind of CRT-based TV or color monitor, install the speakers away from the display device. Any other device liable to be influenced by magnetism (floppy disk drive, cassette tape recorder, video tape player, etc. ) should also be kept at a distance from the subwoofer and surround speakers. When moving the subwoofer, avoid touching the bottom surface, since the speaker unit is located there. ⷠOrient the subwoofer's front face pointing toward the listening position. ⷠThe subwoofer plays back the bass in monaural, making use of the fact that the human ear is not very sensitive to the direction of low-pitched sound. If it is installed too far away, however, the sound from the other speakers may become unnatural. The degree of bass effect can be adjusted by moving the unit farther from or closer to the wall. Labels located on the rear of each speaker indicate whether they are designed for front or surround use. ⷠSpeakers installed to the right and left should be separated by about 1. They should be installed at equal distances from the television, and at equal heights from the floor. ⷠOptional speaker stands can be purchased to facilitate optimal mounting of the surround speakers at or slightly above the listener's ear height. Also, do not install the unit where there is too much dust or high humidity, as these can cause malfunctioning or breakdowns. (Avoid cooking tables and other locations where the unit would be exposed to heat, steam and soot. ) · Keep the subwoofer away from devices such as cassette decks which are sensitive to magnetic fields. ⷠDo not place cups, glasses, or other containers with fluids on top of the units, since the units may be damaged if the liquid spills. ⷠThe installation location selected should have a sturdy floor surface. Mounting the subwoofer on a long-pile carpet should be avoided, since the carpet may touch the driver's diaphram, causing distorted sound. ⷠPlease install the subwoofer away from the antenna cable of the receiver, as noise can be caused with installation close to the antenna cable. In such a case, use the subwoofer at a position away from the antenna and the antenna cable, or when playback of extra bass is not required, switch off the power for the subwoofer. ⷠThe front grilles on front/center/surround speakers cannot be removed. Do not try to forcibly remove them since doing so may damage the grille. [. . . ] If the trouble cannot be rectified even after exercising the checks listed below, ask your nearest PIONEER authorized service center or your dealer to carry out repair work. No power is being supplied (Indicator does not light up when POWER switch is turned on) . ⷠTurn the volume knob counter-clockwise to lower the level. ⷠTurn the receiver's output level (volume, bass control, bass boost) counterclockwise to lower the level.
