The standard factory setting is 78, but this does depend on the type and output of the
microphone used and the noise levels in the operating environment.
Experience has showed that a value between 60 and 80 will work in most cases. When the

recommended to note down the optimal level for future reference in the calibration parameter
sheet found in Appendix A.
Factory setting AL: 78.
