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.
