• The speech block can operate on line voltage, with no external power supply, and is operational even during a commercial power failure.
• Incorporates a receiver noise reducing function to improve the handset's howling margin.
• Incorporates auto. PAD, dial mute, DC voltage regulation, and other basic speech functions.
• The cross-point switch can be operated independently.
• Each output of the cross-point switch can correspond to multiple inputs, allowing three- or four-person communication.
• The REC/PLAY amplifiers incorporate ALC and VOX circuits.
• Receiver volume can be increased by 6 .
