LOCATION
Install turntable in a well ventilated location where it
will not be exposed to high temperature or humidity
Do not install the turntable in a location which is
exposed to the direct rays of the sun, or near to
stoves or radiators. Excessive heat can adversely
affect the cabinet and internal components. Also,
installation of the turntable in a damp or dusty en
vironment, may result in malfunction or accident.
(Also avoid installation near cookers etc., where the
turntable may be exposed to smoke from oil, steam or
heat.)
PRECAUTIONS REGARDING INSTALLATION
Install this turntable as far as possible from tuners
and TV sets. A turntable installed in close proximity to
such equipment, may cause noise or degradation of
the picture. Such noise may be particularly noticeable
when an indoor antenna is used. In such a case, make
use of an outdoor antenna, or turn off power to the
turntable.
CONDENSATION
When the turntable is brought into a warm room
from previously cold surroundings or when the
room temperature is suddenly increased, conden-
sation may form inside and the turntable may not
be able to attain its full performance. In cases like
this, use the turntable after allowing it to stand for
about an hour or after raising the room temper-
ature gradually.
CARE OF RECORDS
Use good quality cleaner.
if use is made of a dry type cleaner (velvet or nylon
brush etc.), this can result in records becoming
charged with static electricity which can result in
occurrence of noise. We recommend the use of
damp type cleaners and anti-static sprays which
aiso effectively remove dust.

AFTER COMPLETING, READ THE FOLLOWING
ITEMS AND CONFIRM THAT YOU HAVE DONE
EVERYTHING CORRECTLY.
= Wrong connections and placement can
resuit in malfunction.
@ If connections are made incorrectly, this can
result in ‘no sound output’. Also, if the plugs
of the output leads are nat fully inserted or
ground leads are not properly connected, this
can result in “hum noise’ (emission of a
humming or buzzing sound from the speakers).
@ If the turntable is tilted, this can result in the
symptoms “sound is distorted”, and ‘tone arm
slides across the record’. {f vibration is
conducted to the turntable, this can result in
the symptoms “stylus jumps”, “sound is un-
stable’, and “howling” (howling or thumping
sounds produced by the speaker)
gAlways connect to the amplifier input termi-
nals for MM use (PHONO MM terminals).
gAllow connecting leads to be slack.
After making connections, make sure that con
necting leads are not pulled tight. H leads are tight
this can result in breakage of leads and howling.

sistance of 50 kKQ2.
