Adjust the supports and position the tonometer

WARNING! Only probes are intended for contacting the eye. Avoid touching the eye with
other parts of the tonometer. Do not push the tonometer into the eye.
WARNING! Shorten the cheek and forehead supports of the tonometer only slightly at a
time to prevent the tonometer from getting too close to your eye.
PRECAUTION! Eye detection is based on the difference of infrared reflections received
from the transmitters: the nose side reflects more than the temple side. If the
transmitters become dirty, the recognition may be interfered.
PRECAUTION! Do not cover the eye recognition transmitters or sensor during the
measurement, for example with your fingers. Keep your hand, hair, and objects such as
pillows away from the temple side of your eye, as they produce an infrared reflection
that causes an error.
1. Before the measurement, adjust the forehead and cheek supports to
the correct length. Start with the supports at the maximum length.
You can take the measurement sitting, standing, or lying down (supine
position).

blue and green rings in the probe base are symmetrical.

perpendicularly to the center of your eye. Correct the position
of the tonometer.
