56 Transceiver Family 620X DV14307.03 Issue 04 March 2016
The brightness of the LCD and push-button illumination can be adjusted
between 0% (off) and 100%. Select your brightness by turning
"ROTARY ENCODER". The BRIGHTNESS settings can also be
adjusted in the user menu. Pilots can change the parameter at any time.
BRIGHTNESS settings are separate for each controller therefore this
menu is available on both controllers.
Note: This page is displayed only if dimming input is set to
"NONE". Otherwise the aircraft dimming bus will control the
brightness
The page "ILLUM CURVE" is displayed only if the DIMMING input is
either selected for "14 V or 28 V" dim-bus voltage. The illumination
curve shows the relation between dimming bus voltage and brightness
of the LCD and push-button illumination.
Two adjustable points V1 and V2 define the illumination curve.
Select the respective parameter by pushing the "STO" button and then
adjust the value in horizontal (left/right) respectively vertical (up/down)
direction using the "ROTARY ENCODER".
Note: Menu available on primary and secondary controller.
(1) This parameter defines the horizontal parameter V1x (minimum
values: 1.5 V for 14 V dimming bus and 4 V for 28 V dimming bus). Up
to this value the brightness is zero. When reaching V1x the brightness is
immediately adjusted to V1y.
(2) This parameter defines the vertical parameter V1y which is the level
of brightness that is set when trigger point V1x is reached.
(3) This parameter defines the horizontal parameter V2x (maximum
values: 14 V or 28 V depending on selected dimming input) where the
illumination curve reaches the maximum brightness level.
(4) This parameter defines the vertical parameter V2y which is the
maximum brightness.
