If this happens, either turndown the MASTER VOLUME control or connect components to the input jacks.• Muting of PRE OUT jacks, HEADPHONE jack and SPEAKER terminalsThe PRE OUT jacks, HEADPHONE jacks and SPEAKER terminals include a muting circuit. Because of this, the output signals are greatly reducedfor several seconds after the power switch is turned on or input function, surround mode or any other-set-up is changed. If the volume is turnedup during this time, the output will be very high after the muting circuit stops functioning. Always wait until the muting circuit turns off beforeadjusting the volume.• Whenever the power switch is in the STANDBY state, the apparatus is still connected on AC line voltage.Please be sure to unplug the cord when you leave home for, say, a vacation.(1) DVD SURROUND RECEIVER2 SC-A3L• Note that color blotching may occur on a TV, etc., due to interaction with the speaker system if there is a magnet or an object generatingmagnetic force nearby.Examples: (a) When there are magnets on the door of the rack, stand, etc.(b) When a health device, etc., equipped with magnets is placed nearby.(c) When toys or other objects using magnets are placed nearby.• Note that the illustrations in this instructions may differ from the actual set for explanation purposes.• Be sure to keep the operating instructions.After reading these operating instructions, store them in a safe place. We also recommend filling in the necessary items on the back cover.2 DSW-3L• The built-in amplifier of the active subwoofer (DSW-3L) includes a muting circuit. The output signal is strongly attenuated for several secondsafter the power is turned on. If the volume is adjusted during this time, the output may be extremely high when the muting circuit is deactivated.Be sure to wait for the muting circuit to be deactivated before adjusting the volume.• Note that color blotching may occur on a TV, etc., due to interaction with the subwoofer if there is a magnet or an object generating magneticforce nearby.Examples: (a) When there are magnets on the door of the rack, stand, etc.(b) When a health device, etc., equipped with magnets is placed nearby.(c) When toys or other objects using magnets are placed nearby.• Note that the illustrations in this instructions may differ from the actual set for explanation purposes.• Be sure to keep the operating instructions.After reading these operating instructions, store them in a safe place. We also recommend filling in the necessary items on the back cover.(2) SPEAKER SYSTEM (D-M51DVS only)WARNING:• Be sure to fasten the power cord to a wall, etc., to prevent people from tripping over it or otherwise pulling on it accidentally, causing thesubwoofer to fall.WARNING:• When installing the speaker systems on the ceiling or wall, to ensure safety, have specialists do the installation work.• Be sure to fasten the speaker cords to a wall, etc., to prevent people from tripping over them or otherwise pulling on them accidentally,causing the speaker systems to fall.• Be sure to check for safety after installing the speaker systems.
