Technics SL-DL1 Operating Instructions

Notes and maintenance
M Auto-return operation will not function if you press the
power switch while a record is being played.
The tonearm will rise above the record surface but étay
where it is.
Therefore, if you then press the switchagain to turniton, the
tonearm will go back to the start position,
Be sure to remove all dirt and dust from the stylus tip and the
record.
The cartridge stylus is an extremely delicate and precisely
manufactured device designed for picking up the subtle
nuances of the record grooves. Therefore, be very careful
not to touch it, push on it, or apply excessive force in any
way.
The stylus tip cannot 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
brush to remove dust and dirt by brushing upward.(Fig.14)
Also, use a good record cleaner to remove dust and dirt
from the grooves.
Wipe the cabinet with a soft, dry cloth.
Never use volatile cleaners such as alcohol, benzine or
thinner,
Do not use chemically treated dust cloths. Do not expose the
panel to insecticide spray.
To remove stubborn spots, first puil out the AC plug.
Then wipe the cabinet with a soft cloth slightly moistened
with a mild soap and water solution.
Do not wipe the upper cabinet during play, or the tonearm
may be attracted toward the upper cabinet due to the gene-
ration of static electricity.
Open the upper cabinet gently.
Upper cabinet open/close movement has been factory
adjusted.
However, if movement is not smooth, turn the upper
cabinet adjustment screw (on the underside of the lower
cabinet) one way or the other, as necessary. (Fig. 15)
Always close the upper cabinet completely.
lf the upper cabinet is not completely closed, the stylus
cannot contact the grooves properly and the turntable will
not operate correctly.
Check again before starting play.
Adjust the stylus pressure in the following cases.
Stylus pressure is normatly set to 1.25 g but may be raised
or lowered by £0.25 g.
It may de 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.
In such cases, turn the screw clockwise (+) so the dial scale
shows the desired stylus pressure, as indicated in the
Nlustration. (Fig. 16)
Note:
Do not turn the stylus-pressure adjustment screw further
than the set limits (1.5 g ~1.0 g).
@ Playing special records. .
Use the “search” function for playing the following types of
records. Such records may interfere with correct automatic
operation. This is not a malfunction of the turntable.
* Non-standard size records [standard sizes (ElA, IEC, DIN,
JIS) are 17, 25 and 30 cm]. .
* Transparent or colored records,
* Eccentric records (having off-center holes).
* Badly warped records.
Speed adjustment (Pitch control)
There are strobe-lines cut on the underside of this turntable
platter to indicate correct rotational speed.
If the strobe-line appears to be moving as the turntable
rotates, adjust while playing a record.
Note:
Be sure to place a record on the turntable mat. If no record is
on the mat, the unit will stop rotating after only a few turns.
1. Press the speed selector of the speed to be adjusted.
_ The pitch control works for both 33-1/3 and 45 rpm; use
the control! to adjust rotational speed at both settings.
2. Slowly turn the pitch control in the (+) or (-) direction
until the strobe-line appears to be standing still.
Correct rotational speed is for the speed indicated when
the strobe-line appears to be standing still,
45rpm
33-1/3rpm 5OH2
45rpm
7-33-1/3rpm 80Hz
In the U.S.A. and CANADA use 60Hz lines.
The 5GHz lines are for European countries.
Note:
Strobe dot pattern
This unit's strobe illuminator operates at the AC line
frequency which generally has a 0.2% fluctuation.
This fluctuation, when present, may make the strobe
pattern appear to change. However, actual turntable
speed does not change, because the DC motor is not
affected by AC power line frequency.
