Thank you for purchasing the EX-12 Digital MP3 Audio Player.
The EX-12 is an easy to use, reliable audio source, for all Promotion-
On-Hold applications. The Flash Drive MUST be inserted into the EX-
12 in order to play. The unit is shipped with a generic hold message
stored on the Flash Drive named "Generic.mp3". The EX-12 will
automatically start playing the MP3 file when it is connected to power.
When it gets to the end, it will immediately re-play the file. It repeats
this over and over again to supply constant audio. If you should loose
power, the EX-12 will automatically re-start, from the beginning when
power is re-stored. The EX-12 plays the audio directly from the USB
Flash drive, so there is no initial LOAD sequence on power up. The
unit has a built in 200 milliwatt audio power amplifier so it has plenty
of power for all telecommunication applications. The RCA output has
been design to work with both 8 ohm and 600 ohm inputs.

The EX-12 has a 64 step, user adjustable volume control. To
change the VOLUME, momentarily depress either the UP or DOWN
buttons. Each depression is one step. The preset volume is maintained
even through power outages. If a stereo MP3 file is used, audio is
taken from the LEFT channel on the file. The EX-12 also comes with
an internal TEST speaker so that you can easily test to see if your EX-
12 is playing properly. The maximum audio playback length for an
individual MP3 file is 1 hour.

The EX-12 will only play MP3 type files. Once the new MP3 file
is on your computer, the Flash Drive must be removed from the EX-12
then inserted into a USB port on a computer. The first step is to
Format the FLASH drive. This will erase the old MP3 file. Next copy
the new MP3 to the Flash Drive. Make sure that you EJECT the Flash
Drive before removing it from the computer. Re-insert the Flash drive
into the EX-12.

To test for proper operation, press and hold down the TEST
button. You will hear the audio that is being played. The speaker is
connected directly to the output, so if you hear audio through the
speaker, it's coming out the output. The speaker is for monitoring
purposes ONLY and is not an indication of audio quality.

The EX-12 has no record capabilities at all. You must create new
audio programs on a computer, then convert them to an MP3 format
before you copy them onto the EX-12 USB Flash Drive. MP3 is a
compression technique that reduces the amount of memory needed to
store an audio program. MP3 basically reduces the size of a standard
WAV file to approximately 1/10 of the original, uncompressed size.
This allows the files to be emailed as attachments if needed. The EX-
12 supports ALL MP3 formats. We recommend that all audio files be
generated in a WAV format first, then converted to MP3 at a 44,100
Hertz sampling rate, at 128KBPS. The files can always be identified
by the ".mp3" extension in the name. To create an MP3 file you must
have a computer software package that has the ability to convert a
WAV file into a MP3 file.
