• A nyone who has experienced dizziness, seizures, loss of awareness, blackouts, or other
symptoms linked to an epileptic condition, or has a family history of such symptoms or
conditions, should consult a doctor before using iris recognition.
• B iometric data collected and stored locally by the iris scanner is not intended for any
diagnostic, therapeutic, or preventative medical purposes.
For better iris recognition
The phone may not recognise your eyes when:
• s omething prevents the camera from getting a good view of your irises (e.g. glasses, low
eyelids, recent eye surgery, disease, dirt, damage to the camera, or excessive movement).
• t he lighting is very different from when you recorded your irises (e.g. direct sunlight).
Hold your device about 25-35 cm away from your face with the screen facing towards you.
Registering irises
The device can save the iris data of one person only. You cannot register more than
one set of irises.
