MCU320D NAWAS Alert Terminal

The MCU320D is a modified MCU terminal that has been designed and configured for NAWAS operation.

MCU320N NAWAS Alert Terminal

The MCU320N adds an audible and visual alert feature to our MCU320B Terminal. This alerting feature is activated by a Control Unit on the circuit.

MCU320B

The MCU320B is best suited for “hoot and holler” type arrangements where users listen to traffic on the circuit over the built-in or accessory speaker, and pick up the handset when they wish to speak to others on the circuit. No backroom equipment is required to create the circuit.

MCU320S

The MCU320S is a terminal for use in the FAA network. Typically supplied with an FAA custom overlay.
