Clean the Be.U Mobile
Make sure that the Be.U Mobile is clean. The following sections describe
how to clean the biometric sensor, the touch screen, and the card reader.
Clean and prepare the fingerprint sensor
Dirt, oils, or other material on the sensor can cause an unacceptable
fingerprint image. Check how to clean the sensor in “Every day”. How to
clean the sensor before each capture is described in “Before each
touch”
.
Every day
Warning
Do not use harsh fluids and abrasive materials to clean the
fingerprint sensor.
Clean the fingerprint sensor. Use a microfiber cloth to apply alcohol
to the surface of the sensor. Move the cloth in a left and right direction
until the sensor surface is clean. Repeat this process as necessary. Make
sure that no dirt remains on the sensor.
Prepare the fingerprint sensor. Use a microfiber cloth to apply
fragrance-free skin lotion to the surface of the sensor. Make sure that you
remove all the visible lotion from the sensor to complete the process. The
lotion improves the quality of the fingerprint image.
Before each touch
Clean the sensor with a microfiber cloth to remove any dirt or finger
marks.
Clean the touch screen
Clean the screen with a microfiber cloth. Use tap water. Do not use
solvents. Always use the stylus or your finger tip to select the items. Do
not use finger nails, pens, or pencil erasers.
Clean the card reader
The smart card reader is an opening in the Be.U Mobile case. During wet
conditions, moisture can enter the card reader. If liquids, dust, or other
particles reach the card reader, do not insert a smart card unless the card
reader is clean and dry.
