Before detaching or attaching the headshell, be sure to turn the power of the
amplifier or mixer to the OFF position.
Detaching or attaching of the headshell with the volume control up may cause
damage to the speakers.
Do not turn on the turntable with the platter removed.
When playback is finished, use the tonearm clamp to secure the tonearm in rest
position. If the unit is not to be used for some time, the stylus protector should be
used as well.
The headshell terminals must remain clean to avoid "hum" noise or intermittent
sound. Use a soft dry cloth to remove dust or dirt.
Dust and dirt must be removed from stylus tip and record surface. Failure to do so
may cause undue wear of the record or stylus, and deterioration of tone quality.
When transporting the unit it is suggested that the original packing materials are
used and handled with care. If packing materials are not available, first remove the
platter and wrap it separately. Make sure tonearm is seated in rest with clamp
fastened and a twist tie is recommended for further security. The balanceweight
and headshell should be removed and wrapped separately. The turntable should
then be wrapped in bubble wrap, blanket, soft paper or other packing material.
ACOUSTIC FEEDBACK AND HUM : Feedback usually occurs when the vibrations
from the speakers are picked up by the sensitivity of the cartridge. To avoid this
phenomenon, the speakers should be placed as far away from the turntable as
possible. Also, it is recommended to use the most solid base available for turntable
support and isolation. Hum may be caused by appliances that use thermostats or
transformers and the greatest distance possible from these sources is
recommended.
