Operation
After a period of time the screen may disappear
from view. The length of time is set using the
Full-OSD Time Out setting in the System Settings
menu (described in the Advanced Functions sec-
tion).You may restore the Now Playing screen to
view by pressing either of the
/
Buttons
Ea
, and you may then navigate the menus
as explained above.
NOTE: It is strongly recommended that you use
a screen saver built into your video display to
avoid possible damage from “burn-in” that may
occur with plasma and many CRT displays when
a still image, such as a menu screen, remains on
display for an extended period of time.
Output Level Adjustment
With Source Signals
Normal output level adjustment for the
AVR is established using the test tone, as out-
lined on page 35. In some cases, however, it may
be desirable to adjust the output levels using
program material such as a test disc, or a selec-
tion you are familiar with.Additionally, the out-
put level for the subwoofer and those for the
Stereo modes can only be adjusted using this
procedure.
To adjust the output levels using program mate-
rial, first select the surround mode for which you
want to trim the speakers (see NOTE below),
start your program material source and set the
reference volume for the front left and front
right channels using the Volume Control
d
.
Once the reference level has been set, press the
Channel Select button
C
Ù
and note that
FRONT L LEVEL will appear in the Main
Information Display
Ò
.To change the level,
first press the Set button
F
@
, and then use
the Selector buttons
7
or the
/
¤
buttons
D
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
F
@
and then press the Selector
buttons
7
or the
/
¤
buttons
D
to select
the next output channel location that you wish
to adjust.To adjust the subwoofer level, press
the Selector buttons
7
or the
/
¤
buttons
D
until WOOFERLEVEL appears in the
Main Information Display
Ò
or on-screen
display (only available if the subwoofer is turned
on).
Press the Set button
F
@
when the name of
the desired channel appears in the Main
Information Display
Ò
and on-screen dis-
play, and follow the instructions shown above to
adjust the level.
Repeat the procedure as needed until all chan-
nels requiring adjustment have been set.When
all adjustments have been made and no further
adjustments are made for five seconds, the AVR
will return to normal operation.
The channel output may also be adjusted using
the full-OSD on-screen menu system. First, set
the volume to a comfortable listening level using
the Volume Control
ı
d
.Then, press the
OSD button
L
to bring up the main menu
(Figure 1). Press the
¤
Button
D
twice until
the
Speaker-tab is highlighted in white.
Press the Set Button
F
to access the menu,
and a second time to activate the
Manual
Configuration
line. Now use the
/
¤
D
to scroll to the ChAdjust line and
press the Set Button
F
to display the Ch
Adjust
submenu.

When the menu appears, the internal test tone
will be turned off.This will allow you to use your
external test disc or other source material as the
test signal. Press the Set Button
F
and use
the
/
¤
Buttons
D
to select the channels
to be adjusted.At each channel position press
the Set Button
F
followed by the
/
Buttons
Ea
to change the output level.
Remember, when you are using a disc with test
signal (e.g. pink noise) or an external signal
generator as the source, the goal is to have the
output level at each channel be equal when
heard at the listening position, with any sur-
round mode selected.When your test source is a
normal disc with music signals, you may adjust
the level for each channel and surround mode as
you prefer, e.g. you may lower the center chan-
nel level when you find it to be too high or
increase the level of the rears when you find it
to be too low with specific surround modes.
If you wish to reset all the levels to their original
factory default of 0dB offset, press the
/
¤
Buttons
D
so that the blue cursor bar is
highlighting the
RESETline and press the Set
Button
F
.After the levels are reset, resume
the procedure outlined above to reset the levels
to the desired settings. When all adjustments are
done, press the
Button
E
consecutive
times to move back to the main menu to make
other adjustments. If you have no other adjust-
ments to make, press the OSD Button
L
to
exit the menu system.
NOTE: The output levels may be separately
trimmed for each digital and analog surround
mode. If you wish to have different trim levels for a
specific mode, select that mode and then follow
the instructions in the steps shown above.
With Stereo modes the adjustment procedure
described above is the only way to trim the out-
put level, e.g. to match the Stereo level with
other modes.
Dim Function
Since the AVR will often be used when movies or
other video programming is viewed under low-
light conditions, you may wish to lower the
brightness of the front-panel displays and indica-
tors so that they do not distract from the video
presentation.You may dim the displays using the
menu system, as shown on page 49, or you may
control the brightness directly from the remote.
Simply press the Dim Button
g
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 above the Standby/On Switch
2
will continue to stay lit as a reminder that the
AVR is still turned on.
Note that all changes to the front-panel bright-
ness 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 the
Dim Button
g
as needed until the displays
are on.
In addition to lowering the brightness of the dis-
plays 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 FadeTimeout line of the
SYSTEM SETUPmenu, as shown on
page 49.
Memory Backup
This product is equipped with a memory backup
system that preserves tuner presets and system
configuration information if the unit is turned off
completely, accidentally unplugged or subjected
to a power outage. This memory will last for
approximately two weeks, after which time all
information must be reentered.
