7. Move to, and scroll the possible minimum ANS level until the required value is displayed:
Range 65->95 [Min ANS 80] Max ANS 90
'Range 65->95' default value: '80'
'Range 55->85' default value: '70'
Note: The 'Min ANS' is the minimum threshold value of the ambient noise in the zone (in dBA). This is
used to limit the range over which the gain may be reduced. When the ambient noise reaches
or is below this value, the Router applies the maximum reduction to the output gain. Therefore
this has the minimum gain, and a lower ambient noise will not reduce the broadcast volume
further.
8. Move to, and scroll the possible maximum ANS level until the required value is displayed:
Range 65->95
'Range 65->95' default value: '90'
'Range 55->85' default value: '85'
Note: The 'Max ANS' is the maximum threshold value of ambient noise in the zone (in dBA). When
the ambient noise reaches or exceeds this value, the Router applies the full configured output
gain for the zone.
9. Save the changes by pressing the SELECT key, or cancel by pressing the BACK key.
