Making Trunked Dispatch Calls
Select the desired subfleet
using the rotary and toggle
switches.
Press the PTT to talk. If the
LED is lit, you are transmitting
normally (the channel is clear to
use). If a dispatch busy tone is
heard, release the PTT and wait for
a call back tone. When the call
back tone is heard, press the PTT
and transmit normally. If a
continuous talk prohibit tone is
heard while the PTT is pressed,
transmission is not possible. The
radio may be out-of-range or not
authorized to access the trunked
system.
When you have finished
talking (transmitting), release the
PTT switch to listen (receive).
