NTEGRATED AMPL FIER L-505uX Precautions
Installation place
This unit shall be installed in a well-ventilated and
effectively heat-released place.
E s p e
c i a l l y, i n s t a l l a t i o n o f t h i s u n i t w h e r e d i r e c t
sunlight is present, where the temperature rises
excessively high such as close to a heater, or where
it is humid or dusty may cause a malfunction even if
heat is efficiently released. Therefore, do not install
this unit in such places.
Ventilation holes
If the amplifier is installed on a rack or the like,secure
ample space for cooling and leave the door open. Do
not pile up other things on the amplifier and never put
articles on it. This can cause malfunctioning.
Note:
For heat dispersal,do not install this equipment in a
confined space such as a book case or similar unit.
P r e c a u t i o n s i n c o n n e c t i n g w i t h o t h e r
components
When connecting this unit to input devices such as a
CD player, an SACD player, a tuner, and a recorder,
be sure to turn off the power of this unit and all other
connected devices. Failure to observe this may
generate a strong noise resulting in speaker damage
or cause a malfunction.
The
pin-plug to be
inserted in each input terminal of
this unit shall be pushed in firmly. If the grounding
terminal is inad-equately connected, noises including
hum may be generated, resulting in an adverse S/N
ratio.
Cautions in connecting speakers
When making speaker system connections, exercise
extra care not to short-circuit between
+ and - of the
speaker terminals and speaker input terminals of this
unit. If a large signal is applied to the amplifier with its
circuit left short-circuited, a large current may be passed
through the output circuit and cause a malfunction.
The sound is not generated shortly after
the power supply is turned on.
This amplifier is equipped with a time muting circuit in
order to separate the output circuit. Therefore, no sound
is generated shortly after the power supply is turned on.
If
the volume control
is moved to a high sound level
before the time muting circuit is canceled, a large
sound is suddenly generated. Please be advised that
the volume control shall be set to a low level at first
and adjusted after sound comes out of the speakers.
Protection circuit
This product is equipped with a protection circuit that
is activated upon detection of overcurrent, abnormally
h i g h t e m p e r a t u r e , a n d D C d r i f t t o p r o t e c t t h e
amplifier and speakers. When the protection circuit is
activated, the output to the speaker terminal is shut
off and the standby indicator blinks to show that this
unit is in the muting state. If the protection circuit is
frequently activated even when disconnecting the
power plug from the wall outlet and turning on the
power again after a lapse of a certain time, please
consult your dealer.
Batteries
Caution:
Batteries used for remote controller shall not be exposed
to excessive heat such as sunshine, fire or the like.
Repair and adjustment
When repairs or adjustments are needed, please ask
the dealer where you bought the unit.
Cleaning
For cleaning, use a piece of soft cloth to wipe the unit
such as cleaning cloth available on the market. If the
unit has become very dirty, remove the dirt with soft
cloth absorbing a small amount of neutral detergent,
and then wipe the unit with dry cloth. Do not use
a solvent like benzine or thinner because such a
substance can often damage the exterior.
