5.3.4 Backlight

Use this tab to set the module backlight and signalling LED brightness levels separately.

Backlight – set the backlight brightness value for the day mode. Set the value as a percentage of the maximum possible LED brightness.

Signaling LEDs – set the signaling LED brightness value for the day mode. Set the value as a percentage of the maximum possible LED brightness.

Note

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 device and, in general, increase the power consumption of the device. A low LED brightness value, on the other hand, may, if the device is placed in direct sun, result in a lower LED on/off contrast and potential LED state identification problems.
