Output Level Trim Adjustment
Normal output level adjustment for the AVR45 is established using the Test Tone, as outlined on page 19. In some cases, however, it may be desirable to adjust the output levels using program material such as a test disc, or a selection you are familiar with. Additionally, the output level for the subwoofer may only be adjusted using this procedure.
To adjust the output levels using pro- gram material, first set the reference volume for the front left/right channels using the Volume Control ôz. If you wish to vary the difference between the left and right channels, use the Balance Control 7.
Once the reference level has been set, press the Channel Select button h

Memory Backup
This product is equipped with a memory backup system that preserves tuner pre- sets and system configuration informa- tion if the unit is accidentally unplugged
or subject to a power outage. This mem- ory will last for approximately two weeks, after which time all information must be reentered.
Processor Reset
In the rare case where the unit’s opera- tion or the displays seem abnormal, the cause may involve the erratic operation of the system’s memory or microprocessor.
To correct this problem, first unplug the unit from the AC wall outlet and wait at least three minutes. After the pause, reconnect the AC power cord and check the unit’s operation. If the system still malfunctions, a system reset may clear the problem.
To clear the AVR45’s entire system memory, including tuner presets, output level settings, deley times and speaker configuration data, first turn the unit off by pressing and releasing the Master Power Switch 1so that it pops out from its normal recessed position. Next, press and hold the AM/FM $and the Dolby Pro Logic îbuttons while pushing the Master Power Switch
1in to turn the unit back on. Note that once you have cleared the memory in this manner, it is necessary to re- establish all system configuration settings and tuner presets.
If the system is still operating incorrectly, there may have been an electronic discharge or severe AC line interference that has corrupted the memory or microprocessor.
If these steps do not solve the problem, consult an authorized Harman Kardon service depot.
