HIIM MID IIOISE

In any high fidelity installation, hum may be caused by the
interconnection of a turntable. tuner and amplifier. and
speakers as the result or wiring. ditterent grounding or
locations at components.

if hum is experienced with your unit, disconnect everything
but the speakers from the unit. Plug in the turntable and
ii hum or howling appears. move the turntable away from
the speakers as much as possible.

Note hum may also be induced by defective cable connec-
tions or by running the cables too close to strong Ac field,
When your unit picks up noise during the reception at
broad-casts, causes are mostly due to external objects
such as fluorescent lamps and house appliances using
motor or thermostat, or others that may Induce the noise.
Either relocating the unit away from the noise sources or
using an improved outdoor antenna may readily solve the
problem. in the event you cannot find the cause consult
your dealer or a qualitied electrician.
