Sensor cleaning
The fingerprint sensor can become soiled by user's fingers, dust, or other sources. This contamination may
affect image quality, degrading authentication performance. It is therefore recommended that you
periodically clean the Signo 25B sensor.
In order to avoid scratching the senor surface use soft lint-free material (or a cotton swab), with gently
movements to clean the capture area.
Note: Optical cleaning products that are used for glasses or cell phone glass surfaces can be used to
clean the sensor area.
Caution: Do not use acidic liquids or abrasive materials to clean the sensor.
Disinfecting the sensor
To disinfect the sensor, use Ethanol or Isopropanol in a concentration of up to 70% on a soft, lint-free cloth
or a cotton swab and gently wipe the capture area.
If a haze is left on the fingerprint sensor, gently dab the area with a soft cloth, dampened with a mild
ammonia-based glass cleaner. Do NOT wipe the area.
Caution: Do not pour cleaning fluid directly on the fingerprint capture area.
Caution: Do not submerge the sensor in liquid.
Caution: Do not rub the fingerprint capture area with any abrasive material, including paper.
Note: To minimize the spread of germs, it is recommended to wash or sanitize your hands before and after
using the fingerprint reader.
