Before using the terminal
53
･
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 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 correctly recognized.
･
Registration/Authentication of fingerprint may be
difficult with your thumb as the center of the whorl of the
fingerprint may be displaced or distorted. Try as much
as possible to slide your finger so that the center of the
whorl of the fingerprint passes the center of the
fingerprint sensor.
･
If the fingerprint is not correctly read, a warning
message appears.
･
If 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, fingerprint
authentication may be unavailable. In this case, perform
fingerprint authentication while touching a metallic part
(frame, external connector, etc.) of the connected device
or after disconnecting the terminal.
･
Fingerprint authentication technology does not
guarantee complete identity authentication or
verification. Note that DOCOMO assumed no
responsibility for any damage caused by use of this
product or unavailability of this product.

Precautions for using fingerprint
sensor
Usage precautions for fingerprint sensor are as follows:
･
The sheet on the fingerprint sensor is a protective film to
maintain waterproofness. Do not remove or poke the
film with a pointed object such as a pen.
･
The fingerprint sensor is waterproof, however
malfunction may occur if a drop or water or dirt adheres
to the surface of the fingerprint sensor or your finger.
Wipe any water or dirt with a soft cloth before use. 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
the surface of the fingerprint sensor from time to time.
- Dirt of dust, sebum, etc. attachment or condensation of
moisture of sweat etc.
･
When the following phenomenon occurs, clean the
surface of fingerprint sensor. The phenomenon may be
improved.
- "Clean surface of sensor." appears
- Fingerprint registration or authentication fails often
･
To clean the fingerprint sensor, wipe its 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.
