the system, you must press BRITR on any bright screen unit to get the bright screen units to their final step of
brightness.
The HS34 and AP74 have a built-in light sensor which can be used to automatically dim all of the screens
connected to a DSAB network. To turn this function on, press AUTODIM. When you enable auto-dim, the
screen does not immediately change brightness. Instead, the system records the unit’s current brightness level as
the desired brightness. From that point on, all networked units react to changes in light intensity and maintain
perceived brightness at the desired level. If auto-dim is enabled and the screen is too bright or dark, continue to
use the BRITR or DARKR buttons as you would without auto-dim. The system records the new set level as the
desired brightness, and auto-adjusts around the new set point.
