Harman Kardon A300 Owners Manual - Page 4

Note that the function selector switch (on the left side) has lour positions. The position masked "FM -AFC" should be selected whenever you wish to tune with the assistance of AFC. The expetiment, described above should be conducted with the select°r switch in this position. Should you wish to disable the AFC circuit fully, however, select the position marked " FM". In this position the AFC circuitry is eliminated and the depressing action of the tuning control is completely ineffective. A very dramatic demonstration of the AFC action can be achieved by switching between the FM and FT.I.AFC positions after tuning slightly off a station with "FM" selected. This is another expression of the experiment describ- ed above. MAGIC EYE The dual bar magic eye, built into the Theme tuner is a further aid to Precise tuning. ON AM: Optimal tuning has been achieved when the minimum total bar area is seen. ON FM: The magic eye operates whether AFC is in circuit or not. Optimum tuning has been achieved when the two right sides of the tuning bars line up. This "picture " will also exist when you are tuned entirely off a station. Between these two conditions, the two right sides of the tuning bare will vary their positions with respect to each other. MAINTENANCE AND REPAIR: In some installations, hum may be encountered due to a voltage difference between the amplifier, tuner and record changer chassis. This may be eliminated by reversing one or all of the AC power plugs. Simply reverse one at a time until improvement ie experienced. Due to the conservative design and high quality coaponents el the Theme, no routine maintenance other than yearly tube -testing is required. Should trouble develop, however, only the most qualified StlViCCIAIIII should beemployed, as special equipment and training is required to properly service high fidelity equipment. This instruction booklet contains diagrams and other inhalation needed by you. repairman. It should be kept available for his use.
