We have installed digital sets in all our childrens Sunday School rooms. The Teachers want to use the internal paging of the sets for storms and lock down situations.

The class rooms have activity and it is easy not to hear the internal page.

I have tried to use the Lo/Hi button to increase the volume, but nothing happens. Is there anything else that controls the internal paging volume.

Are you pressing the Lo/Hi when the feature is active?

Internal Page volume has to be done through programing. The setting is in general Parameters.
