WARNING!
  RISK OF ELECTRICAL SHOCK: Follow all warnings and cautions.
 
ONLY a qualified technician should install, repair, or set options for an MFM.
Do not touch the circuitry on the MFM. Touching the circuitry may result in component damage from electrostatic discharge.

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