Using the MultiTDP Program:
With the program running on your computer, a full MultiTDP instruction manual can be loaded
by selecting Documentation in PDF format under the Help menu. Otherwise, to get started, pull
down the File menu and select TFM-500. The program defaults to serial port com1 but can be
set to com2, 3 or 4 under the Com Port menu. The program is now ready to use. You may
want to upload data from the radio and edit channels or start a new data file. The VHF and
UHF bands are treated as separate radios and must be up or downloaded and edited
separately. Editing is done on a channel by channel basis. Set the channel number you would
like to edit and then modify the frequencies, labels, CTCSS tones, DPL codes, wide / narrow
band setting and scan lists as desired. Press the Save Record button to store the changes
youv’e made to the data base below. After you have edited the channel list your can save your
changes to disk and/or download to the radio. Only channels selected with a check mark will
download. It is recommended to use the Select All command in the Data Transfer menu to
ensure the data base in the radio matches the one in the PC. When download is selected, a
message box will appear on your screen asking you to press FUNC and DN on the radio. Press
these buttons on the radio before you click OK in the message box, otherwise the download
will fail.
