) SENSITIVITY CALIBRATION
To
calibrate
the
sensitivity for optimum tracking and play·
ability, lirst
IUne the gUitar as described in the previous
procedure. Then
engage the sensitivity lunction by depress-
ing
@
ENTER KEY
and holding It down. While holding the
ENTER KEY,
depress
@
CHROMATIC KEY and the SENS,A
(SENSITIVITY) lunction
will be accessed
When in the SensItivity
Calibration mode, the letters "SA'
will appear on the
@
PROGRAM DISPLAY. When a string is
picked. two LEO bar
graphs will appear on the
@
STRING
ASSIGN DISPLAY that
will move across the display from leh
to right. If the
system is properly calibrated. as It should be
Irom the factory, the
upper bar graph will reach the 5 or 6
mark of the
string select guide and will
remain
there as long
as the
String
is
sustained
The
lower bar graph should also
reach the 5
or
6 mark but return to
3 or 4 in approximately 1
second. The lower bar graph
will remain at the 3 or 4 mark
briefly before disappearing
The sensitivity
should only
need
to
be
calibrated when the
strings have been
changed or other work has
been done
on
the gUitar. If the
sensitivity must be calibrated, first check the
height of the HEX Pickup. To
check the height of the HEX
pickup. fret the first
strrng
on the
22nd fret and measure the
height from the bottom
of the string
to
the tOP of the pickup,
The distance
should
be
O.5mm. If the distance is incorrect.
turn the
screw
closest to
the
first
Siring to adjust the pickup
up or down. The procedure
is the same for the sillth string
with one difference. the
distance from the bottom of the
string to the
top of
the
pickup should be O.Bmm. If the
distance is incorrect.
turn the screwciosesl
to
the sixth string
to adjust
the
dlslance.
The next
slep
IS to
check
the
senSitivity of each String as
described previously. If the
sensitivity is off. remove the
rubber
plug
covering
the
sensitiVity trim pots in the back of
the gUllar, The trim
POlS are numbered 1 through 6.
corresponding to
the 1st through 6th strings (1 Sl being the
highest the 6th being the
lowest). Pick a string, If the bar
graph indicates tOO much
senSllivlty,
take
a small, flat head
scr
ewdriver
and CAREFULLY turn the adjustment pot
counter-clockwise until the
string is within specification.
If
t
he bar graph indicates a
loss of sensitivity, again
take
a small
fl
at head screwdnver
and CAREFULLY turn the adjustment
pOI clockwise until the
string
is
within specification. Adjust all
t he strings with thiS procedure.
When calibration is com-
pleted, replace the rubber
plug and
return
the MCl to play
mode.
