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).
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 3 and 4.
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. 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 list. 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-500’s display will show a "+" beside the memory channel number if scan
is enabled.
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.
11. You now have the option to program the guard frequencies by pressing FUNC or press
ENTER to return to normal operating mode.
12. If you pressed FUNC to program the guards, guard"1" transmit frequency will be
displayed with the flashing curser on the second digit. Enter the frequencies for
guard"1" receive/transmit and guard"2" receive/transmit as in step 3 and 4.
13. The alphanumeric labels for guard"1" and guard"2" are entered the same as in step 7
and 8. When the last character is entered, the radio returns to normal operating mode.
2.4 PRIORITY SCANNING, SELECTIVE MEMORY CHANNEL SCANNING AND SCAN LISTS
Instead of breaking up the 200 channels into blocks for scanning, the TFM-500 has 5 scan
lists per band. 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 you can scan at once.
The priority memory channel is always memory position number 1. The priority memory
channel is scanned every other step (ie. 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.
