CHAPTER 7 - MAINTENANCE AND CLEANING

CHAPTER OVERVIEW

This chapter explains how to clean the 4G V-Flex Lite and 4G V-Station Lite device sensor.

The 4G V-Flex Lite and 4G V-Station Lite devices require very little in the way of daily

maintenance except for occasional cleaning and disinfecting.

7.1 CLEANING FINGER PRINT DEVICES

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 damaging the sensor surface or surrounding components.

To clean the fingerprint sensor in a 4G V-Flex Lite and 4G V-Station Lite devices:

1. Remove the electrical power from the device.

2. 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 bathroom 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.

WARNING

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.
