SCN indicator

When the SCAN button is pushed, the radio will light the SCN indicator

and begin scanning. The SCN indicator will flash when the microphone is
placed off-hook to show the radio is no longer scanning (only if the radio is
PC programmed not to scan off-hook).

Transmitting While In Scan:

Transmitter operation in scan is determined by the PC programming of the

radio’s personality. A flow chart is provided in this section to summarize the
scan operation described below.

Off-hook scan not enabled (default):

With off-hook scan not enabled (normal default condition), all scanning
will stop when the microphone is placed off-hook. The SCN indicator
will flash to show all scanning has stopped. If a signal is not being
received when the mic is placed off-hook, the radio will transmit on the
SELECTED channel. If a signal is being received when the mic is placed
off-hook, the radio can be PC programmed (using the "scan transmit
option") to either stay on the receive channel or revert to the SELECTED
channel. When the mic is placed back on-hook, the radio will
immediately start scanning, even if the received channel was still active.

Off-hook scan enabled:

With off-hook scan enabled, moving the microphone off-hook will not
affect scan operation. The radio will continue scanning. If a signal is not
being received, the radio will transmit on the SELECTED channel. If a
signal is being received, the radio can be PC programmed (using the
"scan transmit channel" option) to either stay on the receive channel or
revert to the SELECTED channel when the mic PTT is keyed.

On-hook

When the microphone is on-hook (in the microphone hanger) and the
radio is not receiving a channel, the radio always transmits on the
SELECTED channel.

When the radio is receiving a channel the radio’s personality can be pro-
grammed to transmit either on the received channel or the SELECTED
channel. If the radio was programmed for the SELECTED channel, the
display changes to the SELECTED channel when the transmitter is
keyed.
