radiation is assured.
Especially, installation of this unit where direct sunlight is
present, where the temperature rises excessively high such
as close to a heater, or where it is humid or dusty may cause

Precautions in connecting with other
components
When connecting this unit to input/output devices, be sure to
turn off the power switches of this unit and all other connect-
ed units. Failure to observe this may generate a strong noise
resulting in speaker damage or cause a malfunction.
The pin-plugs to be inserted in the input and output terminals
of this unit shall be pushed in firmly. If the grounding termi-
nal is inadequately connected, noises including hum may be
generated, resulting in an adverse S/N ratio.
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.

amount of neutral detergent, and then wipe the unit with dry
