Installing the Multi-Function Module

The Multi-Function Module (MFM) is an optional adapter for connecting tip/ring (T/R) or supplemental alert devices to any MLX telephone. If you are installing an MFM, do it before you install the MLX telephone.

The MFM provides a modular jack connection for the following adjuncts:

■T/R devices such as single-line telephones, fax machines, modems, credit card verification terminals, cordless telephones, and answering machines. The MLX telephone and the adjunct that is connected to the MFM are independent; they can send and receive calls at the same time. The MFM is the only T/R adapter used with the MLX telephones.

■Supplemental alerts such as bells, chimes, horns, and strobes. These alerts notify people in noisy areas of incoming calls.

The MFM is set for T/R devices or for supplemental alerts by two jumper blocks preset at the factory for T/R operation. The MFM comes with the following:

■a KS22911-L2 power supply

■a 400B or 400B2 adapter

■a D6AP cord
