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 Fingerscan sensor in a 3G or 4G V-Station

 

STEP 1. Remove the electrical power from the device (if possible).

​

​

STEP 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 fingerscan sensor, but they could damage the electronic circuitry surrounding the fingerscan sensor.

 

   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.

​

​

STEP 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.

​

​

STEP 4. Rub the sensor with a clean dry cotton swab or lint-free cloth to remove any traces of cleaning product.

​

​

STEP 5. Reconnect power to the device.
