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.
Memory
If the HK 3390 is unplugged or experiences a power outage, it will retain user settings indefinitely.
