ADVANCED FUNCTIONS Processor Reset There may be instances when you wish to fully reset the AVR 147 to its factory defaults, or the unit may behave erratically after a power surge. To correct erratic behavior, first try turning the Master Power Switch off and unplugging the AC Power Cord for at least 3 minutes. Plug the cord back in and turn the receiver back on. If this doesn't help, try a system reset. NOTES: • A system reset erases all user configurations, including speaker and level settings and tuner presets. After a reset, you will need to re-enter all of these settings. • The RS-232 Reset Button on the rear panel of the AVR 147 does not perform a system reset. DO NOT press the RS-232 Reset Button. To reset the AVR 147, place the receiver in Standby mode (press the front-panel Standby/On Switch so that the Power Indicator turns amber). Then press and hold the front-panel Tone Mode Button for at least 5 seconds until the RESET message appears in the display. 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 AVR 147 is unplugged or experiences a power outage, it will retain user settings for up to four weeks. 52
