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.
