Refer tothe instructions supplied with the speaker system for details. Be sure to use speakersystems with an impedance of 6 Ω/ohms or greater.NOTE:• This system includes digital circuitry which maycause interference such as color blotching orchanges in the color on TVs. If this happens, movethe system and the TV as far apart as possible.NOTES:• Do not plug the power cord into the power outlet until all connections are completed. Be sure to interconnect thechannels (L to L (white) and R to R (red)) properly, as shown on the diagram.• Insert the plugs securely. Incomplete connections may result in noise.• Be sure to connect the speaker cords between the speaker terminals and the speaker systems with the samepolarities ( + to +, – to – ). If the polarities are switched, the sound at the center will be weak, the position of thedifferent instruments will be unclear, and the stereo effect will be lost.• After unplugging the power cord, wait about 5 seconds before plugging it back in.• Note that setting the connection cords (pin-plug cords) next to the power cords may result in humming or othernoise.CAUTION:• Whenever the power operation switch is in the STANDBY position, the unit is stillconnected to AC line voltage.Please be sure to unplug the power cord when you leave home for, e.g.,avacation, etc.System operationsSuch system operations as the timer and the auto power on functions, as well as remote control operations cannot beperformed unless all the RCA pin-plug cords and system connector cords are connected between the units, so be sureto make all the connections properly as shown in the diagram. Also, disconnecting system connectors while the systemis operating may result in malfunctions. Be sure to unplug the power cord before changing connections.Install the sets as shown in one ofthese diagrams. In either case, be surethat the CD receiver’s ventilation holesare not obstructed.(1) Connecting to MD recorder (DMD-M31) or Cassette deck (DRR-M31)FM antennaAM loop antennaRightSubwoofer LeftSpeaker systemsPower plugAC 230 V 50 Hz(Plug into a power outlet)Power plug(for U.K. model)CD receiver (UD-M31)(option)MD recorder (DMD-M31)Side by side installationStacking installation(option)Cassette deck(DRR-M31)
