Harman Kardon AVR 340 Owner's Manual page 43

OPERATION
Simply press the Dim Button h 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 Power
Indicator 2 will remain lit as a reminder that the
AVR is still turned on. The accent lighting for the
Volume Control Ò will dim when the panel displays
are at half brightness.
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 the Dim Button h 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 sys-
tem 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 approximately four weeks, after which time all infor-
mation must be reentered.
