Erasing Macros
It isn’t possible to “edit” a command within a macro. However, you may erase the macro as follows:
1. Simultaneously press and hold the Mute Button and the Macro Button containing the macro until the LED flashes.
2. Press the Surround Button to erase the macro.
Resetting the Remote
To reset the remote to its factory defaults, enter Program mode by simultaneously pressing and holding any Input Selector
and the Mute Button. When the LED flashes, enter the code “333”. When the LED goes out, the remote will have been
fully reset.
Processor Reset
There may be instances where you wish to fully reset the AVR 145 to its factory defaults, or the unit may behave
erratically after a power surge.
For erratic behavior, we recommend you try turning the Master Power Switch off and unplugging the AC Power Cord for at
least three minutes. Try plugging the cord back in and turning the receiver back on. If this
doesn’t work, you may want to try a system reset. NOTE: 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.
To reset the AVR 145, 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 five
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.

Memory
If the AVR 145 is unplugged or experiences a power outage, it will retain user settings for up to four weeks.
