6. Once the Flex Arm is attached, the sensor needs to be positioned so it is aiming
either straight in-line with the user’s eye, above the eye or below the eye (see
Photos). If the user does not need the use of glasses, we recommend removing the
lens from the side where the sensor is mounted. This will give optimum performance
from the sensor and minimum adjustments of the sensor. An Eyeglass lens reflects
light which can sometimes cause interference with the sensor; this is why we
recommend removing the lens if the glasses are not need to see).
