Introduction

The BioSlimDisk fingerprint sensor is a rugged solid-state device to provide years of trouble-free service. Although maintenance and handling requirements for the BioSlimDisk are few in number, observance of a few basics in caring for it will help ensure a high level of performance over the life of the sensor.

Cleaning the Fingerprint sensor

Oily deposits from your finger accumulates on the surface of fingerprint sensor after repeated use. These deposits can inhibit the functionality of the sensor. RiTech recommends that the sensor be cleaned at least once per week, but it should be cleaned anytime an oily residue is visible on sensor surface.

Use Isoporyl alcohol (rubbing alcohol) and a clean cotton cloth or tissue paper to remove oily deposits. Do not use a soiled cloth or tissue paper to clean the sensor. A clean cotton cloth or tissue paper will absorb the deposits, but a solied cloth will smear the deposits over the sensor surface. Rubing alcohol is the preferred cleaning solution because it disolves the oily residue and evaporates quickly.

The use of nylon brushes or souring pads, abrasive cleaning fluids or powders, or steel wool is not recommended.

Caring for the Fingerprint sensor

The BioSlimDisk is designed to perform well even under harsh conditions, nevertheless, some precautions should be taken to avoid damaging the sensor.

  • The BioSlimDisk can be damaged by a discharge of static electricity from your body. However the fingerprint sensor is typically surrounded by conductive plastic which is connected to a ground plane. You should always touch the conductive plastic before touching the sensor in order to discharge any static electricity that may be present on your skin or clothing.
  • Do not place the fingerprint sensor to a heat source such as a radiator or hot plate. The BioSlimDisk can be stored in temperatures ranging from -65 to +150 degrees celcius and can operate in temperatures ranging from 0 to 60 degrees celcius. In addition, the sensor should not be exposed to rain or excessive moisture. The sensor can operate within a range of 5% to 95% relative humidity (non-condensing). With the exception of isoporyl alcohol, do not spill any liquids on the sensor.
  • Do not subject the fingerprint sensor to heavy shocks or vibrations
  • Do not allow the sensor to come in contact with metallic objects
