System Remote Control Functions, continued
In addition to controlling the AVR, the AVR remote is capable of controlling eight 
other  devices,  including  an  iPod/iPhone  device  connected  to  the  AVR’s  front-
panel USB port. During the installation process, you may program the codes for 
each of your source components into the remote. (See Program the Remote to 
Control Your Source Devices and TV
, on page 20, for programming information.) 
To operate a component, press its Source Selector button to change the remote’s 
control mode. 
A button’s function depends on which component is being controlled. See Table 
A13 in the Appendix for listings of the functions for each type of component. Most 
of the buttons on the remote have dedicated functions, although the precise codes 
transmitted vary depending on the specific device being controlled. Due to the wide 
variety  of  functions  for  various  source  devices,  we  have  included  only  a  few  of 
the most-often used functions on the remote: number buttons, transport controls, 
television-channel control, menu access and power on and off. Buttons dedicated 
to the AVR – AVR Power On/Off, Surround Modes, Volume, Mute, Delay and Sleep 
Settings – are available at any time, even when the remote is controlling another 
device.
Power On/Power Off buttons:

settings (use the Up/Down buttons to cycle through the settings):
•  Lip Sync: This setting lets you resynchronize the audio and video signals from 
a source to eliminate a “lip sync” problem. Lip-sync issues can occur when the 
video portion of a signal undergoes additional processing in either the source 
device or the video display. Use the Left/Right buttons to delay the audio by 
up to 180ms.
•  Distance: These settings let you set the delay for each speaker to compensate

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 predertimined 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) and switch 
to the Sleep mode after this amount of time if a source with an analog audio input or 
internal source (FM, AM, USB, iPod, Home Network, vTuner or DMR) is active. See Power 
Indicator/Power Button, on page 5, 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 message 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. In this case you will need to mute the 
TV’s speakers (or switch the setting to Off) when using the AVR for audio.
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. When 
this setting is set to Off, the TV source audio input is set to Optical. When this setting is 
set to On, the TV source audio input is set to HDMI ARC.
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 
controls. Doing so could permanently damage the AVR.
Sleep Timer
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 decreases the play time by 10 minutes, from 90 to 
10 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.
Processor Reset
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 Standby/On switch for more than three seconds to turn the AVR 
off (the Power Indicator will turn amber).
2.  Press and hold the front-panel Surround Modes button for at least 5 seconds until the 
RESET message appears on the front-panel Message 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.
