Privaris BPID™ LFBT Security Device, V1.4

6. GENERAL TROUBLESHOOTING

PROBLEM

Difficulty verifying. Getting solid red light instead of a solid green light.

Try the following, in order, until capture speed increases or a green

light appears:

 Make sure you are using a finger that was enrolled.

 Wipe-off any excess dirt or grease from finger.

 Wipe-off the sensor with a clean finger, swiping it down the

sensor twice to clean it.

 Make sure your fingerprint core is directly over the very center of

the sensor in the Center Position, and not aligned with the bottom

edge of the sensor. Remember the placement reference point

given during enrollment and try to replicate it. Unless you have

very small fingers, you will likely be covering all or a portion of the

grey power button.

 Lift finger and replace it during verification, trying slightly different

positions on and around the Center Position (core). Be sure to

hold in place for 2 seconds before moving to a new position to

give the device sufficient time to interpret your fingerprint.

 Too little or too much pressure may be being applied. While the

sensor is scanning, increase the pressure for a few seconds, and

then decrease it to find the right amount. On a scale of 1 – 5 (5

being the highest) pressure should equal about a “2.” Less than

or greater than “2” can present recognition difficulties.

 Hold the device with only one hand, or just as you did during

enrollment.

 Keep finger flat and level with the sensor. The knuckle should

never be raised or bent.

 If still getting a red light, turn the device off and back on, and try

verifying with a different enrolled finger.
