Move switch #4 to the "on" position to assign address #1 to
the remote. Address #1 will correspond to the #1 BUSY
indicator on the front of the remote. Each remote requires a
unique address so the next remote should be assigned
address #2. This process may be repeated for up to a
maximum of four remotes since there are four addresses. It
is important that the same address is not assigned to more
than one remote.
A CHIME tone may be used to precede a Microphone
Paging. Move switch #8 to the "on" position to enable the
CHIME feature and the "off" position to disable the CHIME.
