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

feature does not change the settings; it merely puts
them in or out of the signal path.

Dim Function

Since the AVR 645 will often be used when movies
or other kinds of video programming are viewed under
low-light conditions, you may wish to lower the bright-
ness 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 44, or you may control the brightness
directly from the remote.

Simply press the

Dim Button

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

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 full-
brightness 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

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 44.

Memory Backup

This product is equipped with a memory backup
system that preserves the system configuration infor-
mation 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.
