Installing Multi-Function Modules
Before installing an MFM, disconnect all trunk and/or power cords
that are attached to the MLX telephone. This is to ensure that no
hazardous voltages are present during installation. Ringing
voltage from the MFM attached to the MLX telephone can cause
electrical shock if adjustments are made while the cords are
connected.
