CAUTIONS ON HANDLE Avoid placing the speaker systems in places exposed to direct sunlight for long periods of time or near heaters or other heating equipment. Placing in humid or dusty places may result in damage. [. . . ] Never play such special signals as a tape recorder's fastforwarding signals or sine waves continuously. When moving the speaker systems, be careful not to apply excess force to the speaker nets. Doing so could damage the speaker units. INSTALLATION WARNING Fix speaker cables to prevent being caught on it that might make loudspeakers fall down. Please check and confirm again after the loudspeaker would have been installed. Do not forget a periodical inspection also. DENON does not take any responsibility for any accident caused by unsteady installing. The tone character produced by speaker systems depends on such factors as the size and type of room, the method of installation, etc. Pay attention to the following points when installing the speaker systems. If the bass sound is overemphasized when the speaker systems are installed directly on the floor, set them on concrete blocks or other hard stands. Note that howling may be produced if the speaker systems are placed on the same stand or shelf as a record player. If there are walls or glass doors behind or in front of the speaker systems, use heavy curtains, etc. , to prevent resonance and reflection. This is an anti-magnet type speaker system which can be used near television sets, etc. , but with some TV sets the colors may become blotchy. If this happens, turn off the TV’s power, wait 15 to 30 minutes, and turn the power back on. The TV’s self demagnetizing circuit will improve the picture. [. . . ] Connect the speaker system for the left channel amplifier’s “L” terminals, the one for the right channel to the amplifier’s “R” terminals, matching the polarities (“<” and “>” marks). Inverting the polarities will result in unnatural sound, with the phase off or no low bass sound. Also check that all four terminal knobs are tightly fastened. Connections (The red terminals on the right side are the “<” terminals, the black ones on the left side the “>” terminals. ) Loosen the terminal knobs, insert the cables’ core wires, then tighten the knobs. Connect to amplifier’s “<” side. [. . . ]
