Connection to the AC mine

The turntable must be connected to a mains voltage of 230 V/50-60
Hz or to 115 V/50-60 Hz in accordance with the voltage information
on the rating plate.

The unit can also be connected to the socket of appropriately fitted

amplifier or receiver (black or red RCA-type p up = right channel,
white RCAdype plug = left channel).

Connect the single ground wire fitted with a terminal clip to the
ground connection on the rear of the amplifier.

if your stereo amplifier or receiver is equipped with 5-poie DiN
phone sockets. a special phono adapter (Dual pan nr. 262 483) is
required for connection of your turntable. This adapter cable can be
obtained as optional accessOry from authorized Dual dealers.

Automatic start, speed selection, stop

With button 9 or 10 select the platter-speed of 33 rpm or 45 rpm. and
select the record size 6 17 or 30 cm by means of the rotary selector.
The quarz-stabillzed speed is displayed by means of the LED on the
appropriate button.

Remove the stylus guard by pulling it forwards and disengage the
tonearm. Depress the start button 11.

The tonearm is automatically lowered onto the record. At the end of
the record the tonearm is automatically returned to the tonearm post
and the unit switched off. You can also switch off the turntable by
depressing the stop button 12 or the button Lift 8 and returning the
tonearm to the tonearm post.

We recommend that the tonearm be engaged on the tonearm post
each time it is returned.

Manual start, oueing control

Position the tonearm over the required point on the record by hand.
Depress button Lift 8. The tonearm is lowered.

The tonearm can be raised at any position - even to interrupt play
briefly - with the button Lift s. The platter continues to turning.

Faults

if malfunctions occur which may be caused by the mains supply.
disconnect the mains plug and then reinsert it.

When blocking the drive by hand. for example by stopping the
platter by hand. the protective circuit becomes effective and shuts
off the motor. This is indicated by the blinking LEDs in the platter-
speied controls 9 and 10. After about 10 seconds the motor restarts
aga n.

Changing and fitting the cartridge

A /~ inch cartridge with a net weight of 2.5 . . .8 9 can be fitted in
place of the cartridge already fitted or on units without a eertridge.
The Dual range of accessories offers appropriate cartrid s.
Loosen screw 13 and remove the head shell by pulling it forward.
Remove the cartridge by loosening the two securing screws. Pull off
the cannection wire on the cartridge. Attach the new cartridge. at
first loosely. on the head shell. Secure the connection wires with the
connection pin on the cartridge.

Red R right channel blue GL left channel ground
Green RG right channel ground white L left channel
Replace the head shell on the tonearrn and secure screw 13. Cut
out the assembly instructions on page 2 of the operation instructions
and place them in between the tonearm bearing and the cartridge.
Now adjust the cartridge parallel to the head shell so that the stylus
is exactly on the line with a clearance of 211 mm.

Stylus

The stylus is subject to natural wear and tear during playing. We
therefore recommend regular checks. which should be carried out
after at least 300 playing hours in the case of diamond-tipped styli.
Your dealer will be happy to do this for you cost-free. Worn out or
damaged (chipped) styli damage records. Therefore. only use as
replacements the stylus types recommended in the technical data of
the cartridge. Other styli often cause audible reductions in quality
and increased wear to records. Remove the stylus by pulling it
diagonally downwards.

To fit a stylus in. follow the procedure in reverse order (fig. 3).

Electrical safety

The unit complies with the lntemational Safety Regulations for radio
and related devices (I50 85) and the EEC guidelines 76/499/EWG.
