0 The wires in this mains lead are coloured In accordance with
the tollowlng code:
Blue: Neutral
Brown: lee

As the coloursoltho wires in themains lead of thisapparatus
may not correspond with the coloured markings identifying
the terminals in your plug, proceed as follows.

The Wlie which is coloured BLUE must be connected to the
terminal which is marked with the letter N or coloured
BLACK, The wire which is coloured BROWN must be con-
nected to the terminal which is marked with the letter L or
coloured RED.

This equipment should be disconnected trom the mains
when not In use.

Before use

This unit is shipped with packing material and spacers
attached to protect it during transport. some parts are
not mounted on the unit and are packed separately.
Please read these instructions carefully before use.

I Removing the packing material
1. Pull oft the tonearm protection spacer.(Fig. 1)
Be careful not to touch the stylus.
2, Remova tape on side of cartridge (This prevents the
stylus assembly from shaking loose during shipment.)

l installation at turntable platter

1. Place the turntable platter on the center spindle. (Fig.2)
Put your fingers through the two holes in the platter.
and line them up with the two recesses underneath.
Follow the reverse procedure if it is necessary to remove
the platter.
Note:
The rotor is connected to the underside of the turntable
platter. (The magnet of the motor is attached to the turn-
table platter.) To maintain optimum performance, extra
care should be taken to preventadhesmn of dust or iron
filings to the magnet and not. to damage the magnet by
dropping it.
Do not remove or loosen the screws, Should the position
of the tixed magnet be altered by loosening the securing
screws, the rated performance otthe unitcannot beguar-
anteed. (Fig. 3)

2. Place the turntable mat on the platter, (Fig. 4)
Line up the protrusions in the turntable mat with the
recesses in the platter (at two places as shown).

Connections

I Connect the output terminals (Fig.5)

Output terminals Amplifier or Receiver

L (White)-> -Channel

R (Red)---9 Channel

GND (Spade lug)-> HIE]

Note:

Always Connect the ground cord to the GNU terminal on
your amp or receiver to prevent hum

Connect the AC power plug

Connect the AC power plug to an AC wall socket.
Caution:
Make sure that the turntables AC line-voltage selector is
matched to your local voltage betore connecting the AC
power plug (Fig. 5)
Never connect to a DC socket. .
If the pro-selected voltage is diflerent from your local
voltage. turn the AC line-voltage selector with a screw-
driver so that it corresponds to your local voltage.
The AC Iinevoltage selector is located at the-bottom of
the base.

Placement

Place the unit in a stable and horizontal position where there
is littlp or no vibration.

Place the unit away from the speakers so that it will be
subiect to as little direct sound radiation as possible.

Do not use or store this unit where it will be exposed todust.
dirt, high humidity or high temperature. Do not place it near
heaters.

Place it in a well ventilated location.

Do not use under direct sunlight. spotlights, or other ex-
tremely bright light sources.

Bright lights may cause misoperation of the optical sensor
system and therefore interference with automatic operation.
This also applies to flashlights or infrared remote control
units brought very close to the turntable.

Do not place it near or on top of a power amplifier, since
power amps radiate much heat.

Place the turntable away Irom the power amp to prevent
hum.

Hum may be caused by leakage flux from the transformer in
the power amplitler (or integrated amp). Therefore. it you
notice hum, try moving the turntable to a slightly different
location. further away from the amp.

If you try to listen to a radio near the turntable while it is
turning, you may hear some interference.

Features

I High performance direct-drive in slim design.

The SL-DLl is divided into upper and lower cabinet halves.
The top half,which also functionsasthedustcover,contains
the linear tracking tonearm, its drive mechanism and optical
sensor, The lower cabinet contains the tonearm servo con-
trol system (microcomputer) and Technics original integral
rotor-platter direct drive motor.

I Simple basic operation. Completely automatic
play.
Turn on the power, out on a record, close the top and press
the start switch After that, everything is handled by the
microcomputer and optical sensor which automatically
detect record size. select correct speed and cue the tonearm
to the lead-in groove.
For non-standard records, front panel speed selectors let
you select the correct speed manually (large 45s, or small
33-1/3 records, tor example).
The tonearm automatically returns to the start position alter
completing play, The tonearm does not move it no record is
on the platter.

I Complex operation also possible.
Although easy operation is a basic feature of this unit,
complex functions are also possible. The search function
allows start, stop switches controlled inward and outward
movement of the tonearm at slow and fast speed, plus line
control in approximately 1 mm steps

I Dynamic balanced linear tracking tonearm
employs optical sensor and groove deflection
angle detection ior extremely stable and accu-
rate tracking.

The ltneartracking tonearm moves across the record surface
in the same wayaslhc cutter head used to makethe record in
tnetirstplace.Thereiorethereis virtually notracking erroror
skating iorce

Located by the stylus is an optical sensor that detects
tracking conditions by means of groove deflection angle
Based on this information, tonearm movement is controlled
to maintain optimum tracking at all times

I A precision DC motor is used tor tonearm drive
to assure quiet and accurate control.
A preci-sion DC motor and low-friction slide bearing assure
accurate tonearm movement.
A 4epoint pivot bearing gimbal suspensron developed by
Technics reduces friction and raises senSitivity while con-
tributing to smooth tracing ability.
