2.3 PROGRAMMING INSTRUCTIONS
To program one of the 200 memory channels in one of the bands:
1.
Select the desired band on the band select (VHF/UHF/VLO) switch. This is required
before any of the programming modes or functions.
2.
Press the
FUNC
key. The display will show the function prompt.
3.
Press the
PROG
key. The display will show the current receive frequency with a
flashing curser on the first or second digit. (The first digit is always a one <1> on
the VHF band and there is no hundreds digit on the VHF LOW band).
4.
Type in the desired receive frequency. If you type in a frequency which is not a 2.5
kHz step, the nearest valid frequency will be automatically selected.
5.
The curser will return to the second digit. You can retype the frequency if you have
made an error or press
ENTER
to continue.
6.
The transmit frequency will be displayed with the curser on the second digit. Follow
the same method as in step 4 and 5.
7.
The channel spacing increment of either 25.0 or 12.5 kHz is now displayed. Use the
M.UP
and
M.DN
keys to select the desired channel spacing for the memory position,
then press
ENTER
.
8.
The alpha-numeric title is now displayed. Use the
M.UP
and
M.DN
keys to scroll
through the alphabet, numbers and symbols. When the desired character is
displayed, press
ENTER
to advance to the next character. Press “1" to backspace.
9.
Keep repeating step six until the last space is set (there are 9 characters). The
display will show SCAN or LOCKOUT to enable this memory position as part of a
scan list or lock it out of the scan lists. Use the
1,2,3,4,5
and
M.DN
keys to toggle
between these functions (for details see paragraph 2.5). Once the desired condition
has been selected, press
ENTER
. The TFM-550’s display will show a "+" beside the
memory channel number if scan is enabled.
NOTE:
Scan function and Scan list feature not provided for VHF Low Band.
10.
The display will now show the current memory number. Type in the 3 digit number
of the memory you want to save to (if different from displayed one) and press
ENTER
.
2.4 PRIORITY SCANNING, SELECTIVE MEMORY SCANNING AND SCAN LISTS
Instead of breaking up the 200 channels into blocks for scanning, the TFM-550 has 5 scan
lists per band (VHF high and UHF only). Any of the 200 channels can be assigned to any
one or 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 can be scanned at once, since all 200 channels can be put into any scan list.
NOTE:
Scanning is not available on the VHF Low band.
The priority memory channel is always memory position number 1. The priority memory
channel is scanned every other step to ensure that no incoming messages are missed.
(Example: 121314151...) 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 200 memory channels are
to be scanned or locked out when the scan function is invoked. To use this feature, follow
PROGRAMMING INSTRUCTIONS found in paragraph 2.3. Once the screen displays
SCAN
or
LOCKOUT
, use the
1,2,3,4,5
or
M.DN
keys to toggle to the desired condition and press
ENTER
. Entering the any or all of the numbers 1,2,3,4 or 5 will include that memory channel
in any of the five scan lists. 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.
