OPERATION (Continued)
Priority-Scan Operation
Operation of the radio with the priority function
selected in the scan mode is similar to that of the
non-priority scan mode with one exception.
If the
radio stops scanning ("locks up") on a non-priority
channel the radio will occasionally look at the
priority channel. If there is activity on the
priority channel the radio will stay on the priority
channel; if not, the radio will go back to the
channel that was interrupted.
B.
Transmitter
To transmit, select the desired channel, lift
the microphone off-hook, monitor to be sure the
channel is not in use, key the transmitter and speak
into the microphone. To key the transmitter press
the push-to-talk (PTT) button on the side of the
microphone.
Two-way conversation is accomplished by
the push-to-talk, release-to-listen operation of the
PTT button on the microphone. When transmitting a
message make the conversation compendious and clear.
Note that the PTT button on the microphone is
not enabled when the microphone is on-hook
(microphone hang-up button connected to chassis
ground). Also, while transmitting, the keyboard is
disabled so accidental pressing of a button on the
keyboard will not interrupt the transmission.
