7-9
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:
1. Remove electrical power from the device.
2. Moisten (do not saturate) a clean cotton swab or a lint-free cloth with rubbing (Isopropyl)
alcohol.
3. Rub the sensor surface with the moistened cotton swab or lint-free cloth. Do not allow the
cleaning product to drip onto any electronic components near the sensor.
4. Rub the sensor with a clean dry cotton swab or lint-free cloth to remove any traces of clean-
ing product.
5. Reconnect power to the device.
7.2. C
LEANING
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 dam-
age the reader housing or other peripheral components.
CAUTION
Disposable ESD-safe wipes, such as ACL Staticide wipes, can be used to
disinfect the sensor and buttons on a daily (or even more frequent) basis. Be
aware that some wipes might not offer the same cleaning power as the prod-
ucts mentioned above and thus should not be relied upon to thoroughly re-
move all residue. Use of wipes does, however, helps keep sensor and button
surfaces hygienic and makes an excellent complement to periodic cleaning.
NOTICE
Never use products such as abrasive cleaning powders, steel wool, scouring
pads, or fine sandpaper to clean the sensor surface. These types of cleaning
products will damage the sensor surface.
