1. Before each authentication it is recommended that the user simply wipe the sensor slowly with a clean dry finger and then position the finger for the authentication This action assures that residue from previous usage will be removed hence giving the best surface conditioning Clean the sensor periodically Dampen a lint free cloth or cotton swab with alcohol or acetone Gently rub the cloth across the sensor surface in a left and right direction Move slowly down the sensor to cover the entire surface area Repeat this process 2 3 times Visually observe that no residual solution remains on the sensor Caution Do not use any abrasive materials to clean the sensor 10 9 Specifications Size 102mm x 68 5mm x 18mm Weight 100g Operating temperature 0 to 50 deg C Storage temperature 20 to 70 deg C Operating humidity 10 to 90 RH non condensing Fingerprint sensor Upek TouchChip Silicon Fingerprint sensor 18 0mm x 12 8mm sensor surface 256 x 360 square pixels 15kV ESD resistance Bluetooth transceiver Class II bluetooth transceiver Battery Replaceable lithium ion battery 3 7V handphone compatible Battery charger Built in Li ion battery charger External power adapter 5V 5 regulated power adapter 500mA or higher Operating Speed Typical fingerprint capture and transfer cycle time lt 6 secs in good communication environment 11 10 Trouble Shooting Below is a compiled list of possible symptom2. is not plugged in or is not turned on then this green status also indicates battery has enough charge Red Unit is on operating normally but battery charge is low Flashing green Unit is in low power standby mode and battery level is OK 5 secs interval Flashing red Unit is in low power standby mode and battery level is low 5 secs interval Flashing orange Unit is off battery is charging 2 secs interval Steady orange Unit is off battery charging is complete Activity LED Flashing blue Power is on and unit is ready 1 sec interval Steady blue Fingerprint captured waiting for host to pull fingerprint information over Flashing blue Fingerprint downloading in process around 5 Hz 7 Battery charging The BlueFin unit has a built in charger for the Li ion battery Use only good quality batteries for the BlueFin To use the built in charger for the battery check that the battery is installed properly in the BlueFin unit Check that the unit is off None of the 2 LEDs are lighted up Plug in the external power adapter Check that the power status LED starts flashing in orange colour The unit is now charging the battery After a period of time the LED should turn to a steady orange colour indicating battery charging is complete This period of time should normally be less than 6 hours depending on how empty the battery is before charging starts Since the ty

9. pe of battery is a Li ion battery it is recommended to charge the battery regularly Using the unit until the battery drains completely flat often will degrade the life of the battery If the unit is not to be used for a long period of time it is better to charge the battery first then remove the battery from the unit before storing 8 Care and maintainence Cleaning the finger In normal usage conditions dirt residue oils or other material can collect on the users finger resulting in degradation of the quality of fingerprint captured For best results it is recommended that the user ensure their fingers and hands are clean and free of any residues before use Remove dirt from the finger by flushing and rinsing fresh warm water over the hands Use water softeners only if only hard water is available If a soap is used to help dirt removal then it is recommended to thoroughly rinse with fresh water followed by a second warm water rinse Mineral deposits can accumulate quickly if soap is used and is sometimes difficult to remove from the skin Alternatively alcohol can be used as a cleaning agent for finger skin in high humidity conditions Rubbing a commercially available alcohol saturated wipe on the surface of the finger prior to placing it on the surface of the sensor is preferred Allow sufficient time for the excess alcohol to evaporate In areas were skin may be dry lotion may be applied to moisten the skin Cleaning the sensor
