Advanced Remote Control Programming

Remote Channel-Control Punch-Through
the punch-through feature allows you to operate one component while setting certain 

groups of controls to operate another component. for example, while using the Avr controls 

for surround modes and other audio functions, you may also use the remote to operate the 

transport controls of your blu-ray disc player. or while using the remote to control video 

functions on your tv, you may also use the remote to change channels on your cable box.
to program punch-through control while operating any device:
1.  for three seconds press and hold the Source Selector button for the main device the 

remote will be operating. the Source Selector will light up, go dark and then light up 

again, indicating the remote is in program mode and that you may release the button.

2.  Select the type of punch-through programming.
  a) for channel-control punch-through, press the channel up button.
  b)  to program transport-control punch-through, press the play transport-control button.
3.  press the Source Selector button for the device whose channel or transport controls 

you will use while operating the device selected in the first step. the Source Selector 

button will flash to confirm.

for example, to watch the tv while changing channels using the cable box, press and 

hold the tv button until it lights. then press the channel up button, followed by the cable/

SAt button.
to undo punch-through programming, follow the same steps as above, but press the 

same Source Selector button in Steps 1 and 3.
NOTE: the volume and mute controls are always dedicated to the Avr.

Programming Macro (Activity) Commands
In addition to their normal functions, you can also use the 0 – 9 number buttons and Avr 

power on button to store macro (Activity) commands – up to 11 of them. each macro 

can send out up to 19 commands at one time from a single button push. Any Avr remote 

control button’s function from any mode (except the back/exit button, the light button, 

and the Activity button) can be programmed into a macro.
NOTE: use caution when programming complicated macros. It isn’t possible to program 

a pause or delay before sending additional commands after a “power on” command, and 

the component may not be ready to respond to commands immediately after powering on.
to program a macro:
1.  to enter the programming mode, simultaneously press and hold the Activity button and 

the number button or Avr power on button to which you want to assign the macro.

2.  press in up to 19 commands that you want stored in that macro button. during each 

successive button selection, the Source Selector button led will blink once. press the 

Source Selector button for each device (or Setup button for the Avr itself) before you 

enter individual commands. this step counts as one of the 19 commands allowed for 

each macro.

•  you can select functions from another mode by first pressing the corresponding 

Source Selector button and then the buttons where those functions are located 

within that mode. pressing a Source Selector button also counts as one command.

•  for power on, press the Avr or device power on button.
•  for power off, press the Avr or device power off button.

3.  press the Activity button to end the programming process. the last Source Selector 

button (or the Setup button) will flash three times.

It isn’t possible to “edit” a command within a macro. to erase the macro:
1.  press and hold the Activity button and the button into which you programmed the 

macro until the Source Selector or Setup button lights up.

2.  press the Activity button to erase the macro.
to execute a macro:
press the Activity button, then press the button into which you programmed the macro.
IMPORTANT: keep the remote aimed at the components until all of the macro commands 

have been executed. the remote can take up to 10 seconds to send out 19 macro 

commands.

two-channel analog audio signals, as well as composite video signals, are normally 

available at the appropriate recording outputs. to make a recording, connect your audio 

or video recorder to the appropriate Avr output connectors as described in the Making 

Connections section, insert blank media in the recorder and make sure the recorder 

is turned on and recording while the source is playing. refer to the recording device’s 

instructions for complete information about making recordings.
NOTES:
1.  the Avr only records analog audio signals. It does not convert digital audio signals 

to analog.

2.  hdmI and component video sources are not available for recording.
3.  please make certain that you are aware of any copyright restrictions on any material 

you record. unauthorized duplication of copyrighted materials is prohibited by law.

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.

to reset the remote to its factory default condition, simultaneously press and hold the tv 

Source Selector button and the “0” number button. when the tv Source button relights, 

enter the code “333.” when the tv button goes out, and all of the Source Selector buttons 

flash, the remote control will be reset.

If the Avr behaves erratically after a power surge, first turn off the rear-panel main 

power switch and unplug the Ac power cord for at least 3 minutes. plug the cord back 

in and turn the receiver on. If this procedure doesn’t help, reset the Avr’s processor as 

described below.
NOTE: A processor reset erases all user configurations, including video resolution, 

speaker and level settings, and tuner presets. After a reset, reenter all of these settings 

from your notes in the Appendix worksheets.

To reset the AVR’s processor:
1.  press the front-panel Standby/on switch to place the unit in the Standby mode (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 receiver 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.
