For registration/authentication of your fingerprint, align the
first joint of one of your fingers to the center of the sensor,
press your finger parallel to the sensor and slide it
downward until it passes the fingerprint sensor area. To
prevent authentication failure due to difference in finger
positions at the time of registration and authentication, keep
your finger parallel to the terminal as you slide it.
･
If the sliding movement is too fast or too slow, the
fingerprint may not be recognized properly.
･
Registration/Authentication of fingerprint may be difficult
with your thumb as the center of the whorls of the
fingerprint may be displaced or distorted. Try as much as
possible to slide your finger so that the center of the whorls
of the fingerprint passes the center of the fingerprint sensor.
･
If the fingerprint is not correctly read, a warning message
appears.
･
If the fingerprint registration or authentication is started with
the finger put on the fingerprint sensor, activation may be
unavailable. Put the finger off from the fingerprint sensor
and retry the operation.
･
When connecting the terminal using a USB cable to a device
which requires grounding such as a desktop PC, make sure
that the device is grounded in advance. If the connected
device is not grounded, the fingerprint authentication may
be unavailable. In such a case, disconnect the terminal from
the device and retry the fingerprint authentication.
･
Fingerprint 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.

Precautions for using fingerprint sensor
Precautions for using fingerprint sensor are as follows:
･
The fingerprint sensor is waterproof; however, malfunction
may occur if water or dirt adheres to the surface of the
fingerprint sensor or your finger. Wipe any water or dirt
surface with a soft cloth. Also, wrinkled finger with water
may cause malfunction.
･
The following conditions may cause failure or damage:
- Strike or give a hard shock
- Scratch or pick with a pointed object
- Rub hard with a fingernail or hard object such as metal
piece of strap and scratch the surface of the fingerprint
sensor
- Scratch or stain the surface of the fingerprint sensor with
soil etc.
- Cover with a sticker or paint with ink etc.
･
The following conditions may make fingerprint scanning
difficult or reduce the authentication performance. Clean
occasionally the fingerprint sensor surface.
- Dirt of dust, sebum, etc. attachment or condensation of
moisture of sweat etc.
･
If you have the following problem, clean the fingerprint
sensor surface. The phenomenon may be improved.
- Fingerprint registration or authentication often fails
･
When cleaning the fingerprint sensor, wipe dirt surface with
a dry, soft and static-free cloth. Long-term use may cause
the fingerprint sensor to get dusty, but do not try to remove
the dust with a pointed object even in such a case.
･
Static electricity may cause malfunction. Before placing the
finger on the fingerprint sensor, eliminate static electricity
by touching a metal object with the hand etc. Take particular
care in dry seasons such as winter.
