Requirement and Preparation
Requirement: this function must be in access level 2. The manual VA reset can be
assigned to a button of an emergency microphone. Please refer to the software
manual for further details. If the emergency reset shall be made by an external
switch, then assign this function to a control input. The connection to the switch
should be monitored and the switch shall be put into access level 2.
The zone status is indicated by buttons assigned for zone selection on a remote
microphone. So assign the same VA zones or VA zone groups to zone selection
buttons as are available for the manual controls.
