Five basic controls are used to receive FM broadcasts through the 730: FUNCTION, VOLUME, BALANCE, and FM MUTING. Make the following adjustments to these controls after activating the SPKRS-1 sw:tch: [1] FUNCTION --FM [2] BALANCE -Neutral (12 o'clock) [3] FM MUTING -Out [4] Tuning -Use this control to move the dial pointer to the extreme end of the dial scale. [5] VOLUME -Advance until hiss is audible IGI MONO -Out You should now hear a mild hissing or rushing sound -this is atmospheric noise picked up by the tuner section. Depress the FM MUTING button and the noise disappears: it has been muted. Turn the tuning knob in either direction until a broadcast signal is received. The FM MAX QUIET meter should have deflected and should now be registering the relative quality of the FM signal you are receiving. Note that the meter detects to the left in an increasing degree as signal quality improves. Maximum obtainable deflection to the left represents the best listening point.' It the broadcast is in stereo, the red STEREO beacon is lit; the beacon does not light when an FM station is broadcasting monophonically. If you have a stereo station tuned press the MONO switch in. The 730 is now receiving the stereo broadcast monophonical y. In addtion, the red STEREO beacon light is disabled. This feature is useful for weak stereo stations where reception is accompanied by a large amount of noise. The program can be received inonootionicelly without the noise.. Very weak monophonic stations may be receiver. if FM MUTING s oefeated, but tuning from station to station is no longer noise-free The upper dial scale of the 730 is cal'orated for FM broadcast station `frequencies from 88 to ' 08 MHz. Each FM station in your area has an assigned frequency trial falls within these limits. You can use the ;Purninated dial pointer and scale of the 730 to find any station in your area if you know the assigned frequency. Similarly, the lower dial sca'e is calibrated for AM stations .n your area, which have assigned frequencies ranging from about 550 kHz to 1600 kHz. Note that when an AM station is being tuned in the FM MAX QUIET meter deflection is from left to right. In other words the best listening point ;s \Amen the meter !s as far to the right as possible. For convenience, a third "logging" scale w:th arbitrary numbers from 0-100 is proVoeci so you can simplify the task of memorizing the var.ous assigned frequency numbers of the FM and AM stations in your area. With :.he 'ogging scale, all you need remember is that your favorite FM station is at 80 on the logging scale, select FM, tune to 80, and lister. The preceding examples give you a working familiarity with the primary controls of the 730. Muting Adjustment The MUTE ADJ control on the rear panel controls the signal threshold at which muting action takes place when the FM MUTING pushbutton is activated. The control has been set at our factory to accommodate the majority of FM reception conditions. If you wish to readjust this control, depress the FM MUTING pushbutton and tune away from any station. Turn the MUTING ADJ control until the interstation noise (hiss) disappears.

Harman, Kardon's extraordinary Quieting meter actually indicates the signal-to-noise ratio or the quality of the received signal.
