Precise

is espe-
cially important with cartridges
specified
lor low tracking forces.
The tonearm needs to
be balanced only
once unless a cartridge
of
a
different
weight is substituted.
Applying
tracking force
With the
tonearm balanced at
"0",
apply
tracking
force by turning the calibrated
dial to the desired number. The Dual
pro-
vides for
applying
tracking force in
a con-
tinuing range
from
0
to
5,5
grams.

force, follow the instruc-
tions
provided
