Using the Master/Secondary Switch
The CID-941’s
M/S
(master/secondary) switch lets
you easily connect up to four CID-941 Caller ID mod-
ules to the same phone line, so you can receive Call-
er ID and Call Waiting information at more than one
phone on that line. Simply set
M/S
on one of the CID-
941’s to
M
, and set it to
S
on all (up to three) others.
Notes:
• If you connect only one CID-941 to a phone line,
set its
M/S
switch to
M
.
• If
M/S
on more than one (or none) of the CID-
941’s is set to
M
, incoming calls might be discon-
nected.
• You can also connect other Caller ID modules
that do not have the Call Waiting function to the
same phone line as your CID-941’s, as long as
the total number of Caller ID modules connected
to the line does not exceed four.
