OPERATION
Output Level Trim Adjustment
Normal output level adjustment for the AVR 445 is established using EzSet/EQ, as outlined on pages 26�28. In some cases, however, it may be desirable to trim 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 can only be adjusted using this procedure. To adjust the output levels using program material, first set the reference volume for the front left and front right channels using the Volume Control )H�. Once the reference level has been set, press the Channel Select Button CE and FRONT L LEVEL will appear in the Lower Display Line $. To change the level, first press the Set Button IF, and then use the �/¤ Navigation Buttons HD to raise or lower the level. DO NOT use the volume control, as this will alter the reference setting. Once the change has been made, press the Set Button IF; then press the �/¤ Navigation Buttons HD to select the next output-channel location that you wish to adjust. To adjust the subwoofer level, press the �/¤ Navigation Button Ho until WOOFER LEVEL appears in the Lower Display Line $ or on-screen display. Repeat the procedure as needed until all channels requiring adjustment have been set. When all adjustments have been made and no further adjustments are made for 5 seconds, the AVR 445 will return to normal operation. The output levels may also be adjusted using the on-screen menu system to either the internal test tone or an external test disc by following the instructions shown on page 31.

EzSet/EQ On/Off
If you wish to turn the filter settings established by EzSet/EQ on or off to demonstrate the impact EzSet/EQ has on the sound of your system, simply press the EzSet/EQ On/Off button A. Using this feature does not change the settings; it merely puts them in or out of the signal path.

Dim Function
Since the AVR 445 will often be used when movies or other kinds of video programming are viewed under low-light conditions, you may wish to lower the brightness of the front-panel displays and indicators so that they do not distract from the video presentation. You may dim the displays using the menu system, as shown on page 42, or you may control the brightness directly from the remote. Simply press the Dim ButtonW once to dim the front panel to half the normal brightness level; press it again to turn the displays off. Note that when the displays are dimmed or turned off, the blue lighting around the Standby/On Switch 1 will continue to stay lit as a reminder that the AVR is still turned on. The accent lighting for the Volume Control ) will remain at its normal level, rather than dim when the panel displays are at half-brightness. Note that all changes to the front-panel brightness level are temporary; the displays will return to fullbrightness after the AVR is turned off and then on again. To return the displays to full-brightness without turning the unit off, press Dim Button W as needed until the displays are on. In addition to lowering the brightness of the displays or turning them off completely, you may wish to have them appear whenever a button on the remote or front panel is pushed, and then gradually fade out after a set time period. You may do this by making the appropriate settings in the VFD FADE TIME OUT line of the ADVANCED SELECT menu, as shown on page 42. Memory Backup This product is equipped with a memory backup system that preserves the system configuration information and tuner presets if the unit is accidentally unplugged or subjected to a power outage. This memory will last for at least four weeks, after which time all information must be reentered.
