IMPORTANT
NOTES
In
addition
to
the
items
listed
under
"USING
THE
UNIT
SAFELY"
on
page
16,
please
read
and
observe
the
following:
Power
Supply
•
Do
not
use
this
unit
on
the
same
power
circuit
with
any
device
that
will
generate
line
noise
(such
as
an
electric
motor
or
variable
lighting
system).
•
The
AC
adaptor
will
begin
to
generate
heat
after
long
hours
of
consecutive
use.
This
is
normal,
and
is
not
a
cause
for
concern.
•
Batteries
should
always
be
installed
or
re¬
placed
before
connecting
any
other
devices.
This
way,
you
can
prevent
malfunction
and/or
damage
to
speakers
or
other
devices.
•
A
battery
was
installed
in
the
unit
before
it
left
the
factory.
The
life
of
this
battery
may
be
limited,
however,
since
its
primary
purpose
was
to
enable
testing.
•
Before
connecting
this
unit
to
other
devices,
turn
off
the
power
to
all
units.
This
will
help
prevent
malfunctions
and/or
damage
to
speak¬
ers
or
other
devices.
Placement
•
Using
the
unit
near
power
amplifiers
(or
other
equipment
containing
large
power
transform¬
ers)
may
induce
hum.
To
alleviate
the
prob¬
lem,
change
the
orientation
of
this
unit;
or
move
it
farther
away
from
the
source
of
inter¬
ference.
•
Do
not
expose
the
unit
to
direct
sunlight,
place
it
near
devices
that
radiate
heat,
leave
it
inside
an
enclosed
vehicle,
or
otherwise
sub¬
ject
it
to
temperature
extremes.
Excessive
heat
can
deform
or
discolor
the
unit.
4
FEATURES
•
We
have
recreated
the
classic
fuzz
sound
of
the
late
60's
using
the
latest
technology.
•
The
unit's
completely
discrete
design
contains
no
ICs
whatsoever,
resulting
in
a
low
noise,
low
current
consumption
unit.
•
You
can

on
the

3
Maintenance
•
For
everyday
cleaning
wipe
the
unit
with
a
soft,
dry
cloth
or
one
that
has
been
slightly
dampened
with
water.
To
remove
stubborn
dirt,
use
a
cloth
impregnated
with
a
mild,
non¬
abrasive
detergent.
Afterwards,
be
sure
to
wipe
the
unit
thoroughly
with
a
soft,
dry
cloth.
•
Never
use
benzene,
thinners,
alcohol
or
sol¬
vents
of
any
kind,
to
avoid
the
possibility
of
discoloration
and/or
deformation.
Additional
Precautions
•
Use
a
reasonable
amount
of
care
when
using
the
unit's
buttons,
sliders,
or
other
controls;
and
when
using
its
jacks
and
connectors.
Rough
handling
can
lead
to
malfunctions.
•
When
connecting/
disconnecting
all
cables,
grasp
the
connector
itself—never
pull
on
the
cable.
This
way
you
will
avoid
causing
shorts,
or
damage
to
the
cable's
internal
elements.
•
To
avoid
disturbing
your
neighbors,
try
to
keep
the
unit's
volume
at
reasonable
levels.
You
may
prefer
to
use
headphones,
so
you
do
not
need
to
be
concerned
about
those
around
you
(especially
when
it
is
late
at
night).
•
When
you
need
to
transport
the
unit,
package
it
in
the
box
(including
padding)
that
it
came
in,
if
possible.
Otherwise,
you
will
need
to
use
equivalent
packaging
materials.

may
result
in
dam¬

Also,
if
you
are
not
going
to
be
using
it
for
an
extended
period
of
time,
disconnect
the
