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.
8. 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 the scan list or lock it out of the scan
list. Use the
M.UP
and
M.DN
keys to toggle between these functions (for details see
paragraph 2.5). Once the desired condition has been selected, press ENTER. TheTFM-
138 display will now 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.1 or 2 digit
memory numbers must be entered as 3-digits with zeroes preceding them.
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 to 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

2.4 SCANNING FUNCTION (5 second talkback delay)
1. To start scanning of the memory channels, press FUNC then SCAN.
The radio will scan through all the preset memory positions (see next 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.
Therefore if while scanning, you hear a call for you:
1. 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.
2. During communications the five second timer is reset from the last Rx or Tx
signal experienced.
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.
