Cautions for Handling the Fingerprint
Sensor
●
The following actions may damage the fingerprint
sensor or cause it to malfunction. Read this
information carefully to avoid damaging the
sensor.
– Dropping an object on the fingerprint sensor, or
otherwise subjecting it to a strong impact
– Scratching the surface of the fingerprint sensor,
or poking it with a pointed object
– Pressing a hard object such as a fingernail or
metal item against the fingerprint sensor
– Touching the fingerprint sensor with dirty hands
– Placing a sticker on the surface of the fingerprint
sensor, or covering the surface with ink or
another substance
●
If fingerprint authentication fails frequently, the
fingerprint sensor may be dirty. Clean the surface
of the fingerprint sensor regularly.
●
When cleaning the fingerprint sensor, use a soft
dry cloth to wipe dirt off the surface.
●
Do not use a pointed object to remove any dirt that
accumulates around the fingerprint sensor. Doing
so may cause the fingerprint sensor to
malfunction.
●
Touching the fingerprint sensor while charged with
static electricity may cause the fingerprint sensor
or scanner unit to malfunction. Before touching the
fingerprint sensor, discharge any static electricity
by touching a piece of metal. Be especially careful
during dry periods, such as the winter season,
when the likelihood of being charged with static
electricity is high.
