2.3 PROGRAMMING INSTRUCTIONS
To program one of the 120 memory channels in the TFM-138B:
1. Press the FUNC key. The display will show the function prompt.
2. Press the PROG key. The display will show the current receive frequency with a
flashing curser on the second digit (The first digit is always a one <1>).
3. 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.
4. The curser will return to the second digit. You can now retype the frequency if you
made an error or press ENTER to continue.
5. The transmit frequency will be displayed with the curser on the second
digit. Follow the same method as in step 3 and 4.
6. 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.
7. 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.
8. Keep repeating step 7 until the last space is set. The display will show SCAN or LOCKOUT
to enable this memory position as part of the scan list or to lock it out of the scan list. Use the
1,2,3,4,5
keys to add the channel to the corresponding scan list or press
M.DN
to clear the
channel from all scan lists. (for details see paragraph 2.4). Once the desired condition has
been selected, press
ENTER
. The TFM-138B's display will later show a "+" beside the
memory channel number if scan is enabled.
9. 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.
10. You now have the option to program the guard frequencies by pressing
FUNC
or press
ENTER
to return to normal operating mode.
11. 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.
12. 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. If the
guard is be be programmed for 12.5 kHz narrowband operation, use the QUICK GUARD
PROGRAMMING FEATURE described in paragraph 2.12. A memory position must be
programmed to the 12.5 kHz mode then the contents can be quickly downloaded to GD1 or
GD2 memory positions.
Programming of memory is disabled when the internal entry disable jumper is set. Alternatively
any transceiver can be programmed by an IBM PC or compatible computer. See section 2.14
