Adjustments 7-3
7.1.2 Brightness and Contrast Adjustment
Monitoring the brightness and contrast adjustment is one of the most important factors for proper
image qualities. If set incorrectly, the gain, TGC, dynamic range or even acoustic output have to be
changed more often than necessary to compensate.
The adjusting buttons are shown as follows:
Brightness adjustment:
<1>, <2> refer to the brightness control keys with a sun marked at the top. Key <1>, marked
with a “-” on the top, can be used to decrease the brightness, while key <2>, marked with a “+”
on the top, can be used to increase the brightness.
Contrast adjustment:
<3>, <4> refer to the contrast control keys with a moon marked at the top. Key <3>, marked
with a “-” on the top, can be used to decrease the contrast, while key <2>, marked with a “+” on
the top, can be used to increase the contrast.
