Operation

Basic Operation

The HK 3470 is simple to operate, and very sim-
ilar to stereo receivers you may have used in
the past. This section will explain the use of
several features that may be new to you.
• 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 3470 for the first time, it
will be necessary to press the Main Power
button 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 . Once the unit is in standby, you
may begin a listening session by pressing the
System Power Control on the front panel
or the Main Power On button
remote. Note that the Power Indicator
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
or remote .
To turn the unit off at the end of a listening
session simply press the System Power
Control 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 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 .
When you will be away from home for an
extended period of time it is always a good
idea to completely turn the unit off using the
front panel Main Power Switch
