” YOUR P-450
|
The F-450 is a sophisticated fully automatic
belt drive turntable. To ensure proper opera-
tion for the best possible sound reproduction,
please read this manual carefully.
Treat the P-450 with the utmost of care, as it
is extremely easy to Jar fine settings such as
tonearm tracking force out of adjustment. If
the unit is bumped, it is important that all
settings be re-checked.
3
Avoid installing the tonearm side of the P-450
next to the power transformer of your
amplifier.
4
Be sure to locate the P-450in a fiat and level
place, out of the direct rays of the sun. Also
avoid locations subject to vibration and ex-
cessive dust, heat, cold or moisture. Also
avoid placing it directly in front of or too
close to your speakers.

If it becomes necessary to relocate the P-450,
do so with extreme care. If possible, re-
pack the unit in its original packing for
transportation.
Do not attempt to clean the P-450 with
chemical solvents as the unit is coated with a
mat lacquer. Use a clean, dry cloth.
it is extremely important that the stylus tip be
kept free of dirt. Regular cleaning ensures the
best possible sound reproduction.
Keep your records clean. Dirty records reduce
the life of the stylus. A stylus with a diamond
tip should be replaced after every 200— 300
hours of use.
Be sure to read the “troubieshooting” sec-
tion for advice on common operating errors
before concluding that your P-450 is faulty.
