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 10 Mohms, but for equipment with external antenna terminals (tuner, receiver, etc.) and is intended for
or [A] , specified insulation resistance should be more than 2.2 Mohms (ground terminals, microphone jacks
3
headphone line-in-out jacks etc.)
PRECAUTIONS DURING SERVICING
1,
Oo CON OD
Parts identified by the L\ symbol parts are critical for safety.
Replace only with parts number specified.
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.
Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
Use specified unsulating 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)
When replacing AC primary side components (transformers, power cords, noise blocking capacitors, etc.), wrap
ends of wires securely about the terminals before soldering.
c> >
Observe that wires do not contact heat producing parts (heatsinks, oxide metal film resistors, fusible resistors, etc.).
Check that replaced wires do not contact sharp edged or pointed parts.
Also check areas surrounding repaired locations.
Use care that foreign objects (screws, solder droplets, etc.) do not remain inside the set.
VOLTAGE CONVERSION (AP-A305/C only)
Each
machine
is
preset
at
factory
according
to
its
destination,
but
some
machines
can
be
set
to
110V-120V
or
220V-240V
as
required.
If your machine’s voltage can be converted:
Before connecting the power cord or assembling the platter turn the Voltage Selector located on the top of the
cabinet with a screwdriver until the correct voltage is indicated.
Models for USA, Canada, Europe, UK and Sustralia are not equipped with this facility.
NOTE: Cycle conversion is unnecessary since AP-A510/C use a DC motors.
