2.4 PRIORITY SCANNING, SELECTIVE MEMORY CHANNEL SCANNING AND SCAN LISTS
Instead of breaking up the 120 channels into blocks for scanning, the TFM-30 software has
5 scan lists. Any of the 120 channels can be assigned to any one of more of these 5 scan
lists. This means the channels do not have to be repeated for them to be in more than one
block and that you are not limited to the number of channels that you can scan at once,
since all 120 channels can be put into any scan list.
The priority memory channel is always memory position number 1. The priority memory
channel is scanned every other step (e.g. 121314151...) to ensure that no incoming
messages are missed. The priority channel can be locked out, which will result in the normal
scanning of the other memory positions.
Selective memory scanning allows the user to select which of the 120 memory channels are
to be scanned or locked out when the scan function is invoked. To use this feature, follow
the PROGRAMMING INSTRUCTIONS found in paragraph 2.3. Once the screen displays
SCAN
or
LOCKOUT
, use the
1,2,3,4
or
5
key to add the channel to the corresponding scan
list or lists. The
M.DN
key acts as a clear button removing the channel from all scan lists
and displaying
LOCKOUT
. Press
ENTER
when you are happy with your selections. In normal
operating mode the display will later show a "+" beside the memory channel number if it
has been included in any of the 5 scan lists.
2.5 SCANNING FUNCTION (5 second talkback delay)
1.
To start scanning of the memory channels, press
FUNC
then
SCAN
and then the
number (1,2,3,4,5) of the desired scan list.
The radio will scan through all the preset memory positions in the selected scan list (see
above paragraph for priority and selective scan features) and will lock on to the first active
channel in the scan sequence. It will remain on the channel until it becomes inactive.
Scanning will resume again after five seconds of inactivity. To exit the scan mode, press
the
SCAN
key. This will cause the radio to revert back to the normal operating mode.
If while scanning, you hear a call for you:
•
Respond to the call within 5 seconds. When scanning is interrupted by an incoming
signal, the channel will remain open for five seconds before resuming scanning.
•
During communications the five second timer is reset from the last Rx or Tx signal
encountered.
The radio resumes scanning once the Rx or Tx activity has ceased for more than five
seconds. The
SCAN
key must be pressed to exit the scan mode.
2.6 DIRECT FREQUENCY ENTRY MODE
This mode is designed to facilitate quick frequency selection during emergency and other
operational conditions requiring direct operating frequency selection. This operating mode is
disabled along with the programming mode when the internal disable jumper is set.
When the transceiver is in the normal operating mode, press
FUNC
and the desired
operating frequency (e.g. 39.275).
Please note in the above operation, after
FUNC
and the first digit are entered, the LED
display will show memory channel "000" and then the remaining digits in the desired
frequency are shown as they are entered. No alphanumeric message can be entered in this
mode. Operation on the new frequency occurs in both transmit and receive (simplex only)
modes. If RX or TX CTCSS tones/DPL codes are required, they must be programmed in.
