MAINTENANCE
CLEANING
The satin gold anodized finish of the knobs and
heavy aluminum front panel will last indefinitely
with
proper
care and cleaning.
NEVER
use
scouring pads, steel wool, scouring powders, or
harsh chemical agents, such as lye solution. These
will mar the finish. Clean with a soft, lint-free
cloth or cotton swab slightly dampened with a
mild solution of detergent and water.
FUSE REPLACEMENT
The Model 2252 is protected by a 2 amp 250 V
fuse. In the event the fuse blows out, replace it
ONLY
with a fuse of the same type and rating.
Replacement with a fuse of higher rating will not
protect the instrument and will void the warranty.
IN CASE OF DIFFICULTY
If the receiver and the dial lamps do not operate,
make sure the power cord is connected. If the
power cord is all right and your unit is equipped
with an external AC line protector fuse, check the
fuse and replace it if necessary. If the dial lamps
are properly
illuminated
but one channel is
inoperative, check the loudspeaker cord of the
inoperative channel for a short circuit, broken
wire, loose connection or other fault. If the loud-
speaker connections appear satisfactory, check
for a broken, open, shorted, corroded, or discon-
nected shielded cable between the receiver and
the input equipment. Check for improper setting
of the
BALANCE
control.
Look for any other
visible fault. If no fault is noted, turn off the
audio system, then transpose (left for right) the
shielded source input cables at the receiver. If the
opposite
channel
becomes inoperative
when
turned back on, then either the shielded cable or
the input equipment is at fault.
If the same
channel remains inoperative, turn off power and
similarly
transpose the loudspeaker cords. If,
when the system is turned on, there still is no
sound from the same speaker system, then either
the loudspeaker system or the loudspeaker cord is
at fault. If the opposite speaker system fails to
operate, then the receiver is inoperative. Refer the
problem
to
your
nearest authorized
Marantz
Service Facility.
