9.2 Maintenance Instructions
The BioPointe is a very rugged device that can operate trouble-free for many years. Although no stringent
maintenance and handling requirement is required, some basic caring, and precaution is still needed to ensure
good and reliable performance.
Cleaning and caring
Never use a sharp object to scrape deposits from the fingerprint sensor. Permanent damage will result.
Normally do not require routine cleaning of fingerprint sensor if no noticeable degradation of fingerprint
verification performance. However, for general cleaning, wipe the fingerprint sensor with a piece of dry and
soft tissue paper.
Only use 99% pure Isopropyl Alcohol and lightly damp a piece of soft foam, soft cotton cloth or soft tissue
paper to remove oily deposits or dirt from the fingerprint sensor or the enclosure surface.
Do not use wet (soiled or excessive moisture) cloth to clean the sensor or it’s surrounding because the liquid
can diffuse into the enclosure or the fingerprint sensor.
Normally not require to switch off the power supply when cleaning the fingerprint sensor or the enclosure
surface.
After cleaning the fingerprint sensor, always allow two minutes for the liquid to dry up (before resume using
it).
Preventive maintenance
Fingerprint sensor and other electronics devices inside the BioPointe device do not require routine calibration
or preventive maintenance.
The optical based fingerprint sensor can withstand harsh environment and ESD; nevertheless, adequate
precaution has to be taken to prevent degradation. Do not expose the device to intense sunlight, operate or
storage environment exceeding the rated specification. Fingerprint sensor should not be exposed to excessive
moisture or condensation.
Ensure wiring is secured to the screw terminal blocks and the screw terminal blocks are fully inserted.
Inspection maintenance frequency
Conduct weekly inspection to check for damages on the LCD display, key buttons or enclosure. Normally do
not require routine cleaning of fingerprint sensor if no noticeable degradation of fingerprint verification
performance.
