Demons can smell like sulfur, roses, cologne...anything! They can also appear as: an angel of light, a dead person or child, a spirit guide, a healing spirit (reiki), an alien, a fairy, a dwarf, a spirit animal etc! We can't safely discern them! The safest thing to do, is let Jesus and his angels protect us.
The recommendation is therefore that the stimulation should be applied with a 2500Hz carrier medium frequency sinusoidal alternating current, burst at 50 Hz (10ms ON: 10ms OFF) at a maximum tolerable level.
All stimulation was âburstâ at 50Hz (as with the RStim based stimulation). An extension to this work is reported (Ward and Robertson, 1998) in which the carrier frequency which generated the greatest torque was considered (range from 1 to 15kHz, all burst at 50Hz).
