Multi-Line Connections (Pabxs); If You Are Installing The Mfc To Work With A Pabx; Ringer Equivalence Number (Ren) - Brother MFC-730 Owner's Manual

Once you open an ink cartridge, install it in the MFC and use it up
within six months of installation. Use unopened ink cartridge by the
expiry date printed on the cartridge box.
DO NOT refill the ink cartridges. Attempting to use refilled
cartridges may cause damage to the print head and will void your
product warranty.
If the INK EMPTY XXXX error message is on the screen display after
you have installed the ink cartridges, check and make sure that the ink
cartridges are installed correctly.

Multi-Line Connections (PABXs)

Most offices use a central telephone system, or PABX. The MFC will
work with most PABX or key systems that allow a two-wire analogue
connection. However, we recommend that you have a separate telephone
line for your MFC. You can then leave the MFC in Fax Mode to receive
faxes any time of day or night.

If you are installing the MFC to work with a PABX:

1
It is not guaranteed that the unit will operate correctly under all
circumstances with a PABX. Any cases of difficulty should be
reported first to the company that handles your PABX.
2
If all incoming calls will be answered by a switchboard operator, it is
recommended that the Answer Mode be set to Manual. All incoming
calls should initially be regarded as telephone calls.
3
The unit may be used with either pulse or tone dialling telephone
service.

Ringer Equivalence Number (REN)

This equipment has a REN value of 1. A BT line has a "bell ringing"
capacity, or REN, of 4. This means that adding downstream-connected
extension telephones and/or extension bells to a total REN of greater
than 4 may cause a reduction in the bell volume. In extreme cases, it
may cause the auto-answer facility of the machine to fail.
Therefore, up to three additional extension telephones (each assuming a
REN of 1), may be connected downstream of your machine. For an
explanation of "downstream connection, read "Using extension
telephones" which follows.
Unless otherwise marked, a telephone provided by BT may be assumed
to have a REN value of 1.
