Notes and
maintenance
@ Turn down amplifier volume (preferably all the way) before
turning the stand-by switch on (.=) or “()” (4m).
This protects your ears and the speakers from switching
noise.
Make sure the stand-by switch is in the “(')" (41) position
before unplugging or plugging in the AC cord.
Auto-return operation will not occur if you press
the stand-by switch while a record is being played.
The tonearm will rise above the record surface but stay
where it is.
Therefore, if you then press the switch again to turniton, the
tonearm will go back to the start position.
Be sure to remove all dirt and dust from the stylus tip.
The stylus tip can not retain proper groove contact when it
is dirty. This causes bad sound reproduction and excess
wear on the stylus tip and grooves. Therefore, use the
accessory brush to remove dust and dirt by brushing up-
ward, as shown in the diagram. Also, use a good record
cleaner to remove dust and dirt from the grooves
@ Wipe the display panel and cabinet with a soft, dry cloth.
Never use any cleaners containing alcohol, benzine or
thinner
Use of a chemical dust cloth should also be avoided, Be sure
that the display panel is not exposed to insecticide spray
Toremove stubborn fingerprints or grease spots, disconnect
the AC power plug.
Use a soft cloth slightly moistened with a mild soap-and-
water solution,
Do not wipe the display panel during play, or the tonearm
may be attracted toward the display panel due to the gener-
ation of static electricity.
If there is no record on the turntable mat, the tonearm will not
move, even if you press the start button.
This unit uses an optical sensor to detect record size and
whether there is a record on the turntable mat or not.
If no record is on the mat, the turntable will rotate once or
twice and the optical sensor will detect the fact that no
record is present. Therefore, the tonearm will not move.
This safety feature prevents accidental damage to the stylus
tip and cartridge.
This also means that if you place a transparent record (which
may be coloured red, green, yellow, blue, etc.) on the turn-
table mat without using the light-block sheets, the turntable
will operate as if there was no record. Therefore, put the
light-block sheet under the transparent record before
attempting to play it
Use the manual play procedure for records that do not meet
industry standard dimensions.
Always be sure the cabinet is shut completely.
If the cabinet is not locked shut completely on both sides,
the sylus tip will not maintain optimum contact with the
record grooves. Also, open and shut the cabinet carefully.
Do not open the upper cabinet unless the lower cabinet is
supported (when using the unit upright or on its side).
Also, hold onto the upper cabinet when you open it when
using the unit on its side or upright.
If the cabinet is allowed to open suddenly, it is dangerous
and may cause damage
Adjust the stylus pressure in the following cases.
Stylus pressure is normally set to 1.25 grams but may be
raised or lowered by +0.25 grams.
It may be necessary to increase stylus pressure when play-
ing records cut at high levels, or when room temperature
is low, or when the unit easily picks up external vibrations.
This will help prevent distortion and groove-skipping
To adjust stylus pressure, turn either way, as shown in the
diagram. The screw is coupled to the graduated ring.
Note:
Do not turn the stylus pressure adjustment screw further
than the set limits (1.5 g~1.0 g).

Replacement of
cartridge
The cartridge supplied with this unit has a precision polished
elliptical block diamond stylus tip. This will produce excellent
sound quality for about 500 hours of playing time (more or less,
depending on conditions). After that, it should be replaced to
prevent deterioration of sound quality and excess record wear
Since this is an MC cartridge, the stylus itself cannot be re-
moved. The entire cartridge must be replaced. Ask for replace-
ment cartridge EPS-310MC, at your Technics dealer.
