Battery installation Remote control transmitter operation range 2 English NOTES ABOUT THE REMOTE CONTROL TRANSMITTER Remote control sensor 1 Within approximately 6 m (19.7 feet) 3 30° Battery replacement If you find that the remote control transmitter must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones. Notes ● Use only AA, R6, UM-3 batteries for replacement. ● Be sure the polarities are correct. (See the illustration inside the battery compartment.
CONNECTIONS Never plug in this unit and other components until all connections are completed. ● ● When making connections between this unit and other components, be sure all connections are made correctly, that is to say L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. Also, refer to the owner’s manual for each component to be connected to this unit. If you have YAMAHA components numbered as 1, 2, 3, etc.
Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and – markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. Do not let the bare speaker wires touch each other and do not let them touch the metal parts of this unit as this could damage this unit and/or speakers.
