7.1.2 CLEANING
Sensors become soiled with residue, oils, or other contaminants due to contact with
fingers and exposure to the elements. The sensor surface should be cleaned
periodically for performance, aesthetic, and hygienic reasons. Care must be taken when
cleaning the sensor to prevent dam-aging the sensor surface or surrounding
components.
To clean the fingerprint sensor in a V-Station 4G or V-Flex 4G device:
9. Remove the electrical power from the device.
Moisten (do not saturate) a clean cotton swab or a lint-free cloth with rubbing (Isopropyl)
alcohol.
CAUTION
Do not use chlorine-based cleaners, such as bleach, or chlorine-
based bath-room or mildew cleaners. Chlorine-based cleaners will
not adversely affect the fingerprint sensor, but they could damage
the electronic circuitry sur-rounding the fingerprint sensor
.
Do not use solvents such as acetone, methyl ethyl ketone, lacquer
thinner, etc. Solvents will not adversely affect the sensor, but they
are likely to damage the reader housing or other peripheral
components.
