Auto-brightness and back-lit keys

Communication system maintenance and repair often require a technician to trouble-
shoot in bright daylight or in the darkness of night. The light sensor on the front panel of
the N934xC HSA senses the ambient light and automatically adjusts the brightness of
the display and the back-lit keys.
The user can also manually set the brightness of the display, and the brightness of the
back-lit keys, so they can be seen clearly even in any light. The duration of the key light is
settable to provide maximum battery life.
