For a definition of each of these terms please see Appendix 1,

section 10.1. Note that for the OSHA data, the L

Aavg

dB35, please refer to Appendix 1, section 10.2.

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.

The default alarm levels will depend on which display mode is

selected, either ISO or OSHA mode. The default levels are

summarised in the following table.
