Applying Stylus Force
Once the toncarm is balanced at fero, you simply
dial the stylus force. The number on the direct-
reading dial §) is accurate to within 0.1 gram.
The instructions accompanying your cartridge will
give you the range of minimum and maximum
tracking forces iis manufacturer suggests,
As the tonearm of the Dual 10/9 can track flaw-
lewaly os low ox 44 grom, the only limitations on
tracking are those imposed by the cartridge itself,
That ia why you can use any cartridge you prefer
with the Dual 1019, including thove with ultra-high
compliance styli not ordinanly recommended for
ie in automatic tonearrrs.
Applying Anti-Skating Compensation
The Dual 1019 in equipped with continuously vari-
able anti-skating compensation. (Sec page 4, for
full explanation.)
To apply anti-skating compensation for the track-
ing force you have set for your cartridge, simply
rotate the anti-skuting dial [J to the same num-
ber ns on the stylus force dial.

Power Control for Amplifier Shul-Of
Your Dual 1019 is equipped with a unique provi-

Special Adjustments for
Positioning Tonearm
The Dual’s tonearm has been carefully set at the
factory to descend accurately into the lead-in
groove during automatic sturt and for proper height
in cycling, Mot if you should ever want to vary
these positions, you can do so quite casily as
follows:
Adjustment for Lead-In Groove
|. Move record-size selector ewitch to 7° position.
This will expose the adjustment screw through
the opening im the chassis near the tonearm post.
2. If the stylus had touched down outside the bead-
in grooves, turn the screw clockwise (very lightly),
If the stylus had touched down on the recorded
grooves, turn the screw counter-clockwise,
(Alhough i i moet cenreniont 0 ie a 7° record, any aise

Adjustment for Cycling Height
This would be necessary only if the top of the
honcarm head touches the bottom record of the
wack on the changer spindle. In that case, the
height of the tonearm can be lowered by turning
the height adjustment screw [fj clockwise,
