Operation
Operational Description
The Model L3149B Desk Set provides radio system control from a remote location. The desk set sends
control to the remote adapter through a telephone line to control radio functions such as transmit, channel
changes, and monitor. When programmed for local (L3147A) operation, the desk set can be used for
extended local control of the radio system.
Receive audio from the radio system is sent to the desk set via the same line connection in 2-wire
applications, or by using another pair in 4-wire applications.
The numeric keypad buttons are used for selection of different base station frequencies. These
frequencies are dependent upon your radio's capabilities. Changes to system parameters require the use of
the XAC4000A Programming Bundle CD (includes C200 programming software), which is sold
separately. Complete information is contained in the Programming section of this manual.
