mode.
The brightness parameters affect the function, power consumption and
general appearance of your device. A high nametag and button backlight
value may, if the ambient light level is low, dazzle the persons standing in
front of the intercom and, in general, increase the power consumption of
the device. A low LED brightness value, on the other hand, may, if the
intercom is placed in direct sun, result in a lower LED on/off contrast and
potential LED state identification problems.
