Ventilation ­ The unit should be situated so that its location or position does not interfere with its proper ventilation. For example, the unit should not be situated on a bed, sofa, rug, or similar surface, that may block the ventilation openings; or placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings. Heat ­ The unit should be situated away from heat sources such as radiators, stoves, or other appliances that produce heat. 8 CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). [. . . ] q The antenna should be at least two meters (6. 6 feet) from reinforced concrete walls or metal structures. Optional outdoor AM antenna In steel buildings or at a great distance from the transmitter, it may be necessary to install an outside long wire antenna. GND terminal For maximum safety and minimum interference, connect the GND terminal to a good earth ground. A good earth ground is a metal stake driven into moist earth. 5 CONNECTIONS TO THE AMPLIFIER q q Before making any connections, switch OFF the power to this unit and the amplifier or other component. Be sure that the connections from the left ("L") and right ("R") LINE OUT terminals are connected to the corresponding (left and right) input terminals of the amplifier or other component. q If you have a YAMAHA amplifier whose terminals on the rear panel are numbered as 1, 2, 3, etc. , connections can be made easily by making sure to connect the LINE OUT terminals of this unit to the input terminals of the amplifier numbered 2.
