Programming the presets using the configuration file
MegaVoice provides a way to configure the radio preset buttons. This is done via a simple text configuration file
named “FMSET.txt”. The file can be stored in the onboard memory in one of two places: within a hidden
volume* on the player or as a single file in the “root” folder. You can create and edit it using Windows Notepad
or your favorite editor.
When the 2 E Series boots up it will check for the presence of this file, looking first within a hidden volume*. If not
found there it looks in the root of the player. If found it will set the preset buttons to the defined frequencies.
But if a configuration file is not found, then all buttons are pre-programmed to 87.0 MHz and may be
reset by the user. The file should contain a single line of text with the following format:
S:0 frequency1,frequency2,frequency3,frequency4,frequency5
From left to right …
“S” an uppercase “S”
“:” a colon
0 zero
A single space.
A comma-separated list of five button frequencies with no spaces between them. The frequencies are
specified as whole numbers without the decimal point. For example, 87.5 MHz is specified as “875” and
107.0 MHz is specified as “1070”.
The frequencies do not have to be in any particular order and more than one button can be assigned to
the same frequency.
Button frequency assignments may be omitted if desired. If one is omitted, a default value of 87.0 MHz will be
substituted by the player. If the FMSET file is absent, all buttons will default to 87.0 MHz.
The position of the frequency numbers in the list correlates to one of the five programmable buttons on the
keypad in the following way:
frequency1 = , frequency2= , frequency3 = , frequency4 = , frequency5 =
*The “hidden volume” option is limited to players prepared by MegaVoice upon special request.
