before assembling the module onto the Display Head. Fold the cable with a loop
that routes through the slot in the Biometrics Module Back.

9. Separate the Biometrics Module Back from the Biometrics Module Assembly by

gently pivoting the bottom edges of the Biometrics Module Front and Back as
shown below to unlatch the pieces at the top eges.

Using the Biometrics Module

Guidelines for Fingerprint Registration

High quality fingerprint templates are imperative for the security of the biometric
security system. Low quality fingerprint templates can impact future read rates.
Therefore, using the Biometrics Module should be done very carefully. In case of
inexperienced users who are using the module for the first time, the process should be
assisted (guided) by an administrator or experienced user.

Procedures

Prior to using the module make sure the fingerprint sensor is clean: See the Sensor
Cleaning Procedure section.

Normal Usage

Place your finger flat and straight on the sensor. If this is not possible, try to place
your finger on the sensor in the same angle every time.

Registering a New Fingerprint

Multiple images (4) are required to register a fingerprint into the system. Therefore,
great care should be taken to place the same part of the fingerprint on sensor every
time. The best way to achieve this is to:

1. Lean the finger comfortably against the front of the housing with the fingertip

raised.

2. Bend the tip of the finger down to touch the sensor.

3. After the fingerprint image is captured (light blinks), lift tip of the finger up.

Location of the Fingerprint on the Sensor

The core of the fingerprint must be centered on the sensor.

11

The Biometric Module algorithms automatically recognize it if the fingerprint is
placed too low, too high, or too far to the left or right side of the sensor and then
provide the user with feedback to improve the fingerprint placement.

Pressure: Put your finger gently on sensor. Do not press it down too firmly (or too
lightly). Exert approximately the same amount of pressure as if you were pressing a
doorbell button.

Choose the correct finger: To obtain a good fingerprint image, and a good fingerprint
template, the print itself must be a good quality. A damaged fingerprint, e.g. with
cuts, will not result in a high quality template. The most suitable fingers to use are the
index finger or middle finger. The small finger is not recommended because it
typically contains fewer details.

Troubleshooting & Cleaning

Troubleshooting

If the reader is having difficulty acquiring a scan of your fingerprint, consider the
following:

• The reader window may need cleaning, see Cleaning the Reader.

• You may not be touching the reader correctly. In order for the reader to acquire a

good scan of your fingerprint, you must place the pad of your finger—not the
tip—in the center of the oval window, and apply gentle, even pressure. Do not roll
your finger. Pressing too hard distorts your fingerprint. Pressing too lightly does
not expose a large enough area of your fingerprint.

• Make sure you hold your finger on the reader until you see the reader light blink.

This can take longer if the skin is dry. Then, lift your finger. Although you may
use any finger with the reader, your index finger of either hand works best.

• If the reader is capturing your fingerprint (as indicated by the reader blink) and

you have tried all the above suggestions, you may need to re-register your
fingerprint.

Cleaning the Reader

Depending on the amount of use, the reader window may need to be cleaned
periodically.

To clean it, apply the sticky side of a piece of adhesive cellophane tape on the window
and peel it away.

Under heavy usage, the window coating on some readers may turn cloudy from the
salt in perspiration. In this case, gently wipe the window with a cloth (not paper)
dampened with a mild ammonia-based glass cleaner.

Reader Maintenance Warnings

There are several things you should never do when cleaning or using the reader

• Do not pour the glass cleaner directly on the reader window.

• Do not use alcohol-based cleaners.

• Never submerge the reader in liquid.

• Never rub the window with an abrasive material, including paper.

• Do not poke the window coating with your fingernail or any item, such as a pen.

Caution: The fingerprint reader is for indoor home or office use only.

USB Controller Configuration

Check the USB controller configuration using the following steps:

1. Click Start → Settings → Control Panel → System.

2. Click the Hardware tab.

13

3. Click the Device Manager button.

• In the Device Manager verify that you have an entry called Universal Serial Bus

controller.

• If this entry does not exist, you need to contact the vendor of your USB

hardware for information on how to correctly configure the USB controller.

4. If the entry does exist, continue to next step.

5. Open the Universal Serial Bus controller icon by clicking on the plus (+) sign to

the left of the icon. Verify that there is a USB Root Hub icon and an icon for the
USB Port.

• If either of these icons is missing or have exclamation points or red X's on

them, contact the computer manufacturer for information on correctly
configuring the USB Controller.

• If these settings appear to be correct, the sensor may be faulty and should be

replaced.
