A button set to this function allows the user to make a page call to both the loudspeaker extension and the extensions in first calling group, 71.

If an extension already has a button set to this function, creating another button with this function automatically clears the setting from the existing button.

To access this function without a programmable button, press an intercom or call appearance button and dial *70.

This type of button can be used for one touch transfer operation.
