The radiofrequency field has a nominal carrier frequency of 40 MHz
and a maximum output of approximately 40 Watts.  The E- field is
applied to the patient on the sides of the neck through two disc
electrodes approximately 10 cm in diameter.  The electrodes are
located at a distance of 2-4 cm from the skin.

[Eleanor White's comment:  The fact that Dr. Ross Adey mentioned
an "audience" being put to sleep by the LIDA suggests that the
"E-field" electrodes may not play an essential role.  The radio
signal appears to be the primary cause of the sleep/trance effect.]

Optimal repetition frequencies are said to lie in the range from 40
to 80 pulses per minute.  Pulse duration is typically 0.2 sec.  In
an 8 year trial period, the instrument was tested on 740 patients,
including adults and children.  Postivive therapeutic effects were
claimed in more..."
