Caller ID
The caller ID feature of this machine lets you use the caller ID subscriber service offered by certain telephone
companies.
The Caller ID is a telephone service that allows the subscriber to see a display of the caller's phone number as
the telephone rings. It is a fast way to screen your calls. You can respond quickly to calls you missed, because
caller IDs are received and stored in your fax machine memory. Besides the standard Caller ID feature, you can
also select a single caller's phone number and call back.
This feature is not available in certain area.
To get the Caller ID service, you have to apply for it at your local telephone company.
FSK and DTMF are the two modes for displaying your calls. Please ask your local telephone company
for whether your mode is FSK or DTMF. If your local telephone company uses DTMF mode, please
switch your mode.
Contact your local telephone company or Brother dealer in the case that the feature does not work
normally. Caller ID feature is not available in the following situation:
- You have not applied for it at your local telephone company.
- The fax machine is connected to an internal switchboard or other switch device.
- Due to the switchboard problems or line problems of local telephone companies, the feature may
not work in some areas.
Advantages of Caller ID

All businesses profit from a quicker response to customer calls.

Caller ID feature
The Caller ID feature of this machine lets you use the Caller ID subscriber service offered by many local
phone companies.
You can view the list or select one of these numbers to fax to, add to Address Book, or delete from the history.
After a few rings, the screen displays the telephone number of your caller (or name, if available). Once you
answer the call, the Caller ID information disappears from the screen, but the call information remains stored
in the Caller ID memory.
The [ID Unknown] message means the call originated outside your Caller ID service area.
The [ID Withheld] message means the caller has intentionally blocked transmission of Caller ID
information.
You can print a list of the Caller ID information received by your machine.
You can print a list of Caller ID information received by your machine.
Caller ID service varies with different carriers. Call your local phone company to determine the kind of
service available in your area.
