SAVI Dual™ Migraine Therapy Instructions for Use 14
Positioning the Device
With the SAVI Dual in front of you: The treatment buttons should be facing up and the accessory door should
be facing away from you. Place your hands on the sides of the device with your thumbs on the treatment
buttons.
Lift the System over your head. The device should be placed so that it comfortably and naturally cradles the
base of your skull. Hold it firmly against your head.
The curved surface positions the device to fit comfortably against the head and optimize pulse delivery.
WARNING: Transcranial magnetic stimulation should only be applied to the back of
the head as described in the “Positioning the Device” section of this manual.
Do not stimulate over the front of the neck or mouth. Severe spasm of the laryngeal
and pharyngeal muscles may occur. Contractions may be strong enough to close the
airway or cause difficulty breathing.
Do not stimulate over the side of the neck. Stimulation of the carotid sinus nerves,
particularly in patients with a known sensitivity to the carotid sinus reflex, could
result in a sudden drop in blood pressure, slowing of the heart or loss of
consciousness.
Do not stimulate the chest or back. Electrical current into the heart may cause
cardiac arrhythmias.
NOTE: If the device detects an error when it is on, a symbol is displayed. See the
“Understanding System Display Messages” and “Troubleshooting” sections of this manual.
NOTE: The System is a handheld device that comes in direct contact with skin. The housing
of the device is made of polycarbonate, a plastic common in consumer medical products,
and poses no handling risk.
