Notes:
l
Most often, Univeral Night Answer notification is provided by an external
ringer device. Universal Night Answer (UNA) can alternatively be set to
ring over the paging system. See “Paging” on page 14 for more
information.
l
If UNA operates over a external ringer device, it is not recommend that
external paging also be used. Since contacts C, B and M activate for both
UNA calls and external pages, the external ringer device would turn ON
for all pages.
