The trunking transmits the failsoft word on
the failsoft channel, and nothing on the
control channel. When the radio cannot
detect a control channel, it looks at its
failsoft channel. When the radio decodes the
failsoft word it will unmute and
conventional radio operation is possible.
After the radio has locked on the failsoft
channel, the operator can transmit
modulation from the trunking analyzer to the
radio.
6. Press the stop test softkey to terminate
testing.
