Technics SA-5570

OPERATION CAUTIONS
Connection wires
Wires used to connect this unit to other stereo equipment,
such as a record player or a tape deck, should be high-
quality shielded wire with low electrostatic capacity, and
should, moreover, be thick wire and no longer than neces-
sary. Use of this type of wire will minimize the incidence
of induction of unwanted noise or hum, and will avoid loss
of high-frequency characteristics. Especially note that, the
longer the wire, the larger the decrease of high-frequency
characteristics. Be sure that the wire is no longer than
necessary for best results.
Connection caution
Be sure that the connections to the speakers and the input
sources are securely made. If the connections are not
secure, the receiver will not operate normally and may
produce noise.
Cautions concerning operating and changing connec-
tions
After switching on the power, do not attempt to use the
controls for a few moments. The output of this unit is large,
and, if excessive input is applied, damage to the speakers
may result,
For this reason, be sure to decrease the volume before
making connections or disconnections of the input termi-
nals,

Reproduction cautions
if unwanted noise such as hum or “howling” occurs while
listening to a disc or tape, and the receiver is operating
correctly, the noise may be caused by one or more of the
following:
1. If the record piayer is placed directly on or near a
speaker, the sound vibration from the speaker may be
transmitted, causing “howling.”
Move the record player from the speakers or place a flat
cushion under the record player, so that the vibration is
not transmitted to the player.
. Hum might be caused if the shield and center core of
the connection wire are connected in reverse, or if the
motor is not properly grounded.

Circuit protection fuses
if no sound is heard from one or more speakers when the
unit has been installed correctly and the tuning dial is
illuminated, turn off the power and check to see if a circuit
protection fuse (on the rear pane!) has failed.
If a circuit protection fuse has failed, replace it (fuse number
XBA2C40SS0) after determining the cause of the fuse
failure (such as a “shorted” speaker wire) and correcting it.
De not use any fuse except the one Included, or fuse
number XBA2C40SS0.
