Precautions for registering iris
･
If you wear glasses, remove them to register (you can wear
glasses at authentication).
･
Remove sunglasses, color contacts, or circle lenses to
register.
･
Register at an indoor location with no direct sunlight.
･
When registration takes time, open your eyes wide to
increase the scanning precision.
･
Hold the terminal up to your eye level.
･
Keep a distance of around 25 cm between the terminal and
your eyes.
･
Make sure there is no dirt or damage on the camera for iris
authentication.→P153
･
The iris registration is available for one eye. However, both
eyes registration is recommended for ensuring highly
precise authentication.
･
The iris registration can be added for the improvement of
precision at authentication. However, avoid adding iris
registrations of multiple persons because the authentication
of yours may not be available. Also, the additional
registration may not give the stronger effect because the
precision improvement has a limitation.
･
Iris authentication technology does not guarantee complete
identity authentication or verification. Note that DOCOMO
assumes no responsibility for any damage caused by use of
this terminal or unavailability of this terminal.
･
Even when the security unlock preference is set to Iris
authentication, unlocking the screen lock with the security
unlock preference used in combination every 72 hours and
when activating the terminal is required. Do not forget the
security unlock preference used in combination.

Precautions for using iris authentication
･
Authentication performance depends on the condition of
use. The following conditions may make iris authentication
difficult or reduce the authentication performance.
- Wearing sunglasses, color contacts, or circle lenses
- Eyes are swollen severely or your bangs are in your eyes,
and iris is hidden
- Eyes or the terminal gets direct sunlight or reflecting light
- Below water
- The terminal or your body is shaking strongly
- Putting the terminal on an angle or turning it over
- Dirt or damage is on the camera for iris authentication or
LED→P153
･
When authentication takes time, open your eyes wide to
increase the authentication precision.
･
Keep a distance of from 20 to 30 cm between the terminal
and your eyes.
･
Iris may not be detected when light reflects on the lenses of
glasses. In such case, reduce the reflection of the light by
inclining your face, etc.
･
Note that the authentication may be performed when
another person holds the terminal and the terminal is faced
toward you.
