AVR

System Settings

the AVr’s System Settings menu lets you customize in what way many of the AVr’s 

features operate. press the oSd/Menu button and navigate to the System line. press the 

ok button to display the System Settings menu. 

Panel Timeout: this setting allows you to set the AVr’s front-panel display to automatically 

turn off after remaining on for a predetermined time (3 – 10 seconds) each time you use 

a control. Set this to “off” to have the display remain on continually.
Auto Power Off: this setting allows you to set the AVr to automatically switch to the 

off mode after being in the Sleep mode for a predetermined time (1 – 8 hours). See 

Power Indicator/Power Button, on page 4, for more information. It also allows the AVr to 

automatically switch to the Sleep mode after being on for the predetermined amount of 

time. note that it will not transition to Sleep mode this way if the active source has one 

of the digital Audio connectors selected as the Audio Input. See Source Setup, on page 

23, for more information.
Menu Timeout: this setting allows you to set the amount of time (20 – 50 seconds) a 

menu screen will remain on after the last adjustment. Set this to “off” to have the menus 

remain on continually until you press the oSd/Menu button.
Status  Message: when  the AVr  is  turned  on,  the  volume  is  adjusted,  the  source  is 

changed or a change in the input signal is detected, a status message will be displayed 

on the tV screen. Select how long the message remains visible, from 2 to 10 seconds, 

with a default of 3 seconds. Select “off” if you do not wish to see the status messages on 

the tV screen (they will still appear on the AVr’s front-panel display).
Volume Default and Default Volume Setting: these two settings are used together to 

program the volume level when you turn on the AVr. Set Volume default to on, and then 

set the default Volume Setting to the desired turn-on volume. when Volume default is 

set to off, the AVr will turn on at the last-used volume setting from the previous listening 

session.
HDMI  Audio  to  TV:  this  setting  determines  whether  hdMI  audio  signals  are  passed 

through the hdMI Monitor out connector to the video display. In normal operation, leave 

this setting at off, as audio will be played through the AVr. to use the tV by itself, without 

the home theater system, turn this setting to on. 
HDMI  Link:  this  setting  allows  the  communication  of  control  information  among  the 

hdMI devices in your system. turn this setting to on to allow control communication 

between the hdMI devices; turn the setting to off to forbid control communication.
Software Update: If a software upgrade is released for your AVr, installation instructions 

will be available in the product Support section of the web site or from harman kardon 

customer  service.  At  that  time,  you  may  use  this  submenu  to  install  the  upgrade 

software.
IMPORTANT: During a software upgrade, do not power off the AVR or use any of its 

the sleep timer sets the AVr to play for up to 90 minutes and then turn off 

automatically.
press  the  Sleep  button  on  the  remote,  and  the  time  until  turn-off  will  be  displayed. 

each additional press of the Sleep button increases the play time by 10 minutes, with a 

maximum of 90 minutes. the Sleep oFF setting disables the sleep timer.
when the sleep timer has been set, the front-panel display will automatically dim to half 

brightness.
If you press the Sleep button after the timer has been set, the remaining play time will be 

displayed. press the Sleep button again to change the play time.
the front-panel display will count down during the final 10 seconds before going to Sleep 

mode. pressing any button during this countdown will cancel the process and disable 

the Sleep timer.

If the AVr behaves erratically after a power surge, unplug the Ac power cord for at least 

3 minutes. plug the cord back in and turn the AVr on. If this procedure doesn’t help, reset 

the AVr’s processor as described below.
NOTE:  A  processor  reset  erases  all  user  configurations,  including  speaker  and  level 

settings and tuner presets. After a reset, reenter all of these settings from your entries in 

the Appendix worksheets.

To reset the AVR’s processor:
1.  press the front-panel power button for more than three seconds to turn the AVr off (the 

power Indicator will turn amber).

2.  press and hold the front-panel Surround Mode category button for at least 5 seconds 

until the reSet message appears on the front-panel display.

NOTE: After performing a processor reset, wait at least 1 minute before pressing any 

Source Selector buttons.
If  the AVr  does  not  function  correctly  after  a  processor  reset,  contact  an  authorized 

harman kardon service center for assistance. Authorized service centers may be located 

by visiting our web site at www.harmankardon.com.
