CARE AND MAINTENANCE
This
section
describes
the
care
and
maintenance
tasks
that
must
be
performed
to
optimize
the
operation
of
your
Marantz
equipment.
CLEANING
OF
EQUIPMENT
EXTERNAL
SURFACES
The
exterior
finish
of
your
PM-62
will
last
indefinitely
with
proper
care
and
cleaning.
Never
use
scouring
pads,
steel
wool,
scouring
powders
or
harsh
chemical
agents
(€.g.,
lye
solution),
alcohol,
thinners,
bezine,
insecticide
or
other
volatile
substances
as
these
will
mar
the
finish
of
the
equipment.
Likewise,
never
use
cloths
containing
chemical
sub-
stances.
If
the
equipment
gets
dirty,
wipe
the
external
surfaces
with
a
soft,
lint-free
cloth.
If the equipment becomes heavily soiled:
—
dilute
some
washing
up
liquid
in
water,
in
a
ratio
of
one
part
detergent
to
six
parts
water.
—
dipa
soft,
lint
free
cloth
in
the
solution
and
wring
the
cloth
out
until
itis
damp.
— wipe the equipment with the damp cloth.
— dry the equipment by wiping it with a dry cloth.
FUSE REPLACEMENT
if
a
fuse
blows,
unplug
the
equipment
from
the
mains
supply.
Replace
the
fuse
only
with
a
fuse
of
the
same
type
and
rating.
Replacing
the
fuse
with
one
of
a
higher
rating
or
a
slower
action
will
not
protect
the
equipment
and
will
invalidate
the
warranty.
If
the
replacement
fuse
plows
again
after
the
equipment
is
turned
on,
the
equipment
should
be
taken
to
an
authoruized
service
facility.

the
most
cometent
and
qualified
service
technicians
sould
be
allowed
to

Marantz
company
and
its
factory-trained
warranty
station
personnel
have
the
knowledge
and
special
facilities
needed
for
repair
and
calibration
of
this
precision
equipment.
After
the
warranty
period
has
expired,
repairs
will
be

the
equipment
together
with
a
full
description
of
what
you
think
is
abnormal
about
the
equipment’s
behavior.
TROUBLESHOOTING
In case of trouble or abnormal operation of the unit, check the following
before contacting service personnel. What may seem to be a serious
malfunction is often the result of a simple operation mistake. If the
trouble persists after checking the following, please contact your dealer
or nearest Marantz distributor.
The amplifier does not operate and the indicators do not light.
1. Check to see if the power cord is inserted properly into the power
outlet.
The indicators light but the amplifier does not operate.
1. Check to see if the SELECTOR switches and VOLUME control .
are properly set.
Sound is heard from only one of the speakers.
1. Check to see if the BALANCE control is properly set.
2. Switch the power of the unit to OFF, and change the connections of
the left and right speaker cords. If the sound from the same speaker
is still not heard, its connection cord or the speaker itself may be
defective.
Considerable hum noise is heard when the tumtable is played.
1. Check to see if the plugs from the turntable are properly connected
to the PHONO jacks.
2. Connect the grounding wire of the turntable to the GND terminal on
the rear panel of this unit. If it has already been connected, try
removing it.
3. Check to make sure that the phono cartridge is attached securely to
the tonearm.
4. Unplug the power cord and plug it in again after inverting the
orientation of the blades.
What happens when the SOURCE DIRECT switch is pressed:
The audio signal from the program source is directed to the bypass
circuit, which sends the signal through the minimum required circuit
length to minimize signal degradation in the signal path.
Therefore, when the SOURCE DIRECT switch is pressed, the signals
from the DCC and TAPE jacks are not output to the speakers or
headphones.
To output the tape deck signals, the SOURCE DIRECT switch should
be set to OFF.
Remote control operation is not possible.
1. Isthe remote control unit's (RC-62PM) transmitter pointed correctly
at the remote sensor on the front of the Amplifier (PM-62)?
Or, is there an obstruction between the transmitter and the remote
sensor?
2. Are the batteries in the remote control unit (RC-62PM) exhausted?
3. Is there another strong light (from a window, etc.) striking the
Amplifier (PM-62) remote sensor?
4. Isan RCA cord connected to the “REMOTE CONTROL IN” jack on
the Amplifier (PM-62) rear panel?
