Designed for high-speed intelligibility and exceptional reliability paging and dispatching systems, a dual impedance switch for convenient changeover from low to high. The 450 Series II also features a finger-tip control bar (locking or non-locking action) to activate microphone circuit and an external relay or control circuit. With a long-life switch and an ARMO-DUR® casing, the 450 Series II is designed for dependability under all operating conditions. The optional RK1995 split-bar conversion kit provides Monitor/ Transmit switching.

Designed for indoor communication systems — fixed station — including police, fire, transportation, restaurant, and industrial applications.
