WARNING

The 2- and 4-port FXS interface modules have a ring signal generator that is a source of hazardous voltage. Do not touch the RJ11 port conductors, the conductors of a cable (that is, the exposed metal ends of a cable connector) connected to the RJ11 port, or the circuit board when the ringer is active (an incoming call activates the ringer).
