Shure 450 Series II TRANSMIT/MONITOR Switch Conversion KIT, Specifications, Replacement Parts

TRANSMIT/MONITOR SWITCH CONVERSION KIT

When the optional split-bar Transmit/Monitor Switch Conver- sion Kit is installed, the Monitor bar must be depressed before the Transmit switch can be depressed, requiring the operator to verify that the channel is open before transmitting. The Monitor bar can be locked in the “on” position. The Transmit bar is momentary and cannot be locked.

NOTE: Transceiver wiring information must be obtained from the transceiver schematic and/or the manufacturer.
