5.8 Alarm Settings
Alarm levels can be set within the dB35 software based on action
levels for local workplace noise regulations. They can be used by
an employer as a visual indicator of an individual's exposure
throughout the day and can be switched ‘on’ or ‘off’ as per section
5.6. If these pre-determined alarm levels are exceeded then the
blue LED on the front of the CEL-35X will flash. The location of the
LED is shown in Figure 23.
