Basic Operation
Once you have completed the setup and configuration
of your new receiver, it is simple to operate and enjoy.
The following instructions will provide the steps needed
to enjoy the HK 3375:
• Install the two supplied AAA batteries in the remote
as shown. Be certain to observe the (+) and (–)
polarity indicators shown in the bottom of the battery
compartment.
• When using the HK 3375 for the first time, it is
necessary to press the
Main Power Button 1 on
the front panel to turn the unit on. This places the unit
in a Standby mode, as indicated by the amber color of
the
Power Indicator 3. Once the unit is in standby,
you may begin a listening session by pressing the
System Power Control 2 on the front panel or the
Main Power On Button å on the remote.The
Power Indicator 3 will turn red, then green. This
will turn the unit on and return it to the input source
that was last used. The unit may also be turned on
from Standby by pressing any of the
Source Selector
buttons on the front panel 89!#$ & or
remote
ç.
To turn the unit off at the end of a listening session,
simply press the
System Power Control 2 on the
front panel or the
Main Power Off Button ∫ on the
remote.This places the unit in the Standby mode, and
the
Power Indicator 3 will turn amber to remind
you that the unit is ready for operation when a power
command is received from the remote.
When the remote is used to turn the unit “off” it is
actually placing the system in a Standby mode, as
indicated by the amber color of the
Power
Indicator

front-panel
Volume Control Ò or remote Master
Volume Up/Down
π buttons.The volume level is
displayed by the position of the

face of a clock, with the
Volume Indicator Ú indi-
cating the hour. The HK 3375 is playing at the mini-
mum volume level when the
Volume Indicator Ú
points to 7 o’clock; when the Volume Indicator Ú
points to 12 o’clock (straight up), the HK 3375 is
playing at the maximum volume level. It is important
that you make sure never to exceed this maximum
volume level at any time, in order to avoid possible
damage to your loudspeakers due to “clipping”, a type
of distortion that is not audible to the human ear until it
is severe enough to permanently damage most loud-
speakers. It is also possible, depending upon the pro-
gram material, for clipping to occur at volumes below
the maximum volume level.

the
Mute Button ®5. This will cut the output to
all speakers, but it will not affect any recording or
dubbing that may be in progress.When the system
is muted, the

Indicator
Ú will flash. Press the Mute Button ®

again to return to normal operation.

plug from a pair of stereo headphones into the front-

speaker sets, press the

the front panel corresponding to the desired speakers.
