incandescent bulbs. Try shielding the light
guide area with hands and repeat the
measurement.
Low Signal.
Hair may be trapped under the light guide or light
guide might not be making contact with scalp,
Repeat the measurement.

The light on one side of the patient’s head is
brighter than the other and the amplifiers need to
begin the measurement with a lower gain. Re-
take the data of the pair.
Saturated, Start in Reverse
Order.

hematoma and needs to re-take the data in the
reverse order (right side first) to confirm. The

present on the left side (first side of pair to be
measured).
