1. The front display of the AV32R ‘Dual Processor’ is a so-called ‘Vacuum Fluorescent Display’ (VFD), a technology known for excellent
readability and brightness. The average life of a VFD is well over 10 years, requiring no maintenance. However, a VFD will slowly
reduce its maximum brightness over time, but only those segments which are illuminated will become darker over time. So if you show
the same information at high brightness for any prolonged period, e.g. VOL -30.0, then only those segments making up this information
will darken, whilst all others will remain unchanged. As a result if you show any other information, consisting of dark (=aged) and bright
(=unaged) segments, an uneven brightness will be visible. Aging can be reduced by configuring the display to switch off after a few
seconds, as described above.

The brightness associated with
High Level
,
Medium Level
and
Low Level
can be user
configured, selectable from 1 (dark) to 10 (very bright).
This is the brightness the AV32R ‘Dual Processor’ front panel display will switch to after the
AV32R ‘Dual Processor’ is powering up.
The display can be configured to switch to the
After Hold Brightness
level after a
Hold Time
of 1, 2, 3, 5, 10, 20, 30 or 60 seconds. The display will switch automatically switch back to
the brightness level it came from, if the display content changes. Set
Hold Time
to
Keep On
if
you want the display remain on all the time during operation. Set the
After Hold Brightness
to
Off
, if you want the display to switch off.
If the front display is switched off, the blue power/standby LED can also be switched off by
setting the
Blue LED State when display Off
to
Off
. This prevents any unwanted light from
interfering with your display device.
If you have other TAG McLaren products connected to the AV32R ‘Dual Processor’ via
the TAGtronic Bus and you have configured the AV32R ‘Dual Processor’ to transmit its
brightness level via the TAGtronic Bus to other units -for details see page 77 - then they will
synchronise their display brightness including the blue power LED brightness to the AV32R
‘Dual Processor’.
