DO NOT stare directly into the infrared iris recognition LED as prolonged use can cause eye strain.
Do not stare at the iris recognition LED light when your eyes are less than 20 cm (~8 inches) away
from the device, for best results keep your eyes between 25-35 cm (~10 14 inches) away for
optimum recognition.
Note: The Iris scanner is not intended to be used as a medical device and the biometric data
collected and stored locally by the mechanism is not intended to be used for any diagnostic,
therapeutic, or preventative purposes. Please follow all instructions for use of this feature.
For best results, remove eyeglasses and sunglasses. Do not use the Iris scanner in bright sunlight or
areas with excessive reflected light (for example, by the pool or seashore). Do not use the Iris
scanner in low light. Look straight at the device (not up, down or sideways), and hold your head still
for the scan. Tinted contact lenses and surgically repaired or replaced iris lenses may interfere with
operation of the Iris scanner. Do not walk or operate a vehicle while using the Iris scanner.
