OPERATION
VFD OFF: Display goes completely dark except for Power Indicator
to remind you that the receiver is turned on
NOTE: When either the Video 1 or Video 2 source has been
selected, the Dimmer Button on the remote will only affect the
source device (if compatible), and will not affect the HK 3390.
Processor Reset
If you wish to fully reset the HK 3390 to its factory defaults, or if it
behaves erratically after a power surge, first turn the Master Power
Switch off and unplug the AC power cord for at least three minutes.
Plug the cord back in and turn the receiver back on. If this doesn’t
help, you may want to try a system reset.
NOTE: A system reset erases all user configurations, including
tuner presets. After a reset, you will need to reenter all of
these settings.
Place the receiver in Standby mode by pressing the Power Switch so
that the Power Indicator turns amber. Simultaneously press and hold
the front-panel Preset Scan and Mute Buttons for at least five seconds
until the software version number, followed by the RESET message,
appear in the display. The unit will return to Standby mode, and you
may power it on.
If the receiver still does not function correctly after a processor
reset, contact an authorized Harman Kardon service center
for assistance. Service centers may be located by visiting our
Web site at www.harmankardon.com.
Memory
If the HK 3390 is unplugged or experiences a power outage, it
will retain user settings indefinitely.
