The E.F.P.'s "real time, high visibility" green with red
center LED display, allows others to view E.V.P. responses
easily in dark locations. This feature allows users the
ability to capture E.V.P. evidence on video. The device
has a "white noise/ambient noise baseline adjustment"
allowing the user, to set the baseline level on the devices
illuminated scale. This provides a "visual reference" to
see in real time any "addition" or "reduction" of
proprietary frequency noise. The E.F.P.'s built in circuitry
amplifies input signals to high levels allowing users to
visually monitor E.V.P. responses at higher resolution. The
input to the device has (1) 3.5mm stereo plug used to
connect to any recording devices live audio output
(earphone). The E.F.P. also has (1) 3.5mm audio output
which can be used for earphone or mp3 type speakers.
The E.F.P. has a "manual on/off switch" and built in "push
button single LED navigational light". The E.F.P. operates
on one standard "9volt" battery. The current regulation
circuitry in the device provides hours of use.
