Dim Function

Some people find the front-panel messages distracting and would prefer
to dim them or turn them off altogether.
To dim the display, press the Dim Button on the front panel or remote.
Each button press will cycle through the three settings of:
VFD FULL: Normal brightness
VFD HALF: Display is dimmed but still visible; the light inside the
volume knob goes dark
VFD OFF: Display goes completely dark except for Power Indicator
to remind you that the receiver is turned on
NOTE: When the remote is in the device mode for either the
Video 1 or Video 2 source, the Dimmer Button on the remote
will only affect the source device (if compatible), and will not
affect the HK 3490.

Processor Reset

If you wish to fully reset the HK 3490 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, appears
in the display.
The unit will return to Standby mode, and you may power it on.
You may reset the HK 3490 by using a sharp object to press the rear-
panel Reset Button. This method does not erase user configurations.
If the receiver still does not function correctly after a processor reset,
contact an authorized Harman Kardon service center for assistance.

Memory

If the HK 3490 is unplugged or experiences a power outage, it will
retain user settings indefinitely.
