Akai AX80 Service Manual

SAFETY INSTRUCTIONS
SAFETY CHECK AFTER SERVICING
Confirm the
specified insulation resistance between power cord
plug prongs and
externally exposed
parts of the
set
is
greater than lOMohms, but
for equipment with external
antenna terminals (tuner, receiver,
etc.) and
is
intended for
[Cl
or
[aI,
specified insulation resistance should be
more than
2.2 Mohms
(ground
terminals,
microphone jacks,
headphone jacks,
line-in
-out jacks etc.)
PRECAUTIONS DURING SERVICING
1.
Parts
identified
by
the
A
symbol parts
are critical for
safety.
Replace only
with parts number specified.
2.
In addition to
safety, other parts and
assemblies are
specified
for
conformance
with such
regulations as
those
applying to spurious radiation. These
must also
be replaced
only with
specified
replacements.
Examples:
RF
.converters, tuner units, antenna
selector
switches, RF
cables,
noise
blocking
capacitors,
noise
blocking
filters, etc.
3.
Use specified internal wiring.
Note especially
:
1)
Wires
covered with PVC tubing
2)
Double insulated wires
3)
High
voltage leads
4.
Use specified
insulating materials for
hazardous
live parts.
Note especially:
1
)
Insulation Tape
2)
PVC
tubing
3)
Spacers
(Insulating Barriers)
4)
Insulation
sheets for transistors
5)
Plastic screws
for
fixing microswitch
(especially in
turntable)
5.
When
replacing
AC
primary side components
(transformers,
power cords,
noise
blocking
capacitors,
etc.), wrap
ends
of wires securely about the terminals
before
soldering.
6.
Observe
that
wires
do
not contact heat
producing
parts
(heatsinks, oxide
metal film
resistors,
fusible
resistors,
etc.).
7
.
Check
that replaced wires do not
contact sharp edged
or
pointed
parts.
8. Also
check areas surrounding repaired
locations.
9.
Use care
that
foreign objects
(screws, solder
droplets,
etc.) do
not remain
inside the set.
Voltage
conversion
Models
for Canada,
USA, and Japan are not
equipped
with this
facillity.
Each machine is preset at
the factory according to
its des-
tination, but
some machines
can be set to 1
10V, 120V,
220V or
240V
as
required.
If your
machine's
voltage can be converted:
Before conmnecting the
power
cord, trun the
VOLTAGE
SELEC-
TOR located
on the
bottom panel with
a
screwdriver
until the cor-
rect voltage
is
indicated.
