5. Installation on Host (Devices)
Install the module on the device, as shown below, by tightening the four screws in the holes and linking the holder to the wire.
Note: In order to ensure good and convenient fingerprint scanning, it is recommended to install the module on the wall horizontally or at an angle of 0-45 degrees.

6. Demo Testing Procedure
It is required that the first time Users need to install the Device Driver before using the Fingerprint Scanner, and the process is as follows: (If the Users have already installed the Device Driver of SLK ID series Fingerprint Scanner, they can directly test without re-installing it.) 1. Download the ZKFinger SDK compressed package and then double-click the setup.exe file to open.
Page 7

2. On the Setup Wizard, click Next and then click Install to install the driver. Page 8

3. After the completion of the Driver installation click Finish.
4. Connect the Fingerprint Scanner Device to the Computer and go to Control Panel and open Device Manager. If the driver is installed successfully, the Device Name will be displayed on the Computer Management window. Page 9

Page 10

5. Once after the installation of the Device driver, open Demo interface from ZKFinger SDK compressed package, and then click Connect Sensor to connect with the Fingerprint Scanner.
Page 11

6. After the Sensor is connected, the Sensor Count is automatically displayed as 1. (It's equivalent to a user ID. and we can set it on User ID, when we need to register many User.
Page 12

7. The default ID of the system is 1. Click Register and press the finger three times on the Fingerprint Scanner to Register and click Save Image.
Page 13

8. After successful Registration, click Identify (1:N) and press the registered finger on the Fingerprint Scanner for verification.

7. Operating Instructions
Guide to Place the Finger
It is recommended to use the index finger, middle finger or the little finger for registration. Proper Positioning of Finger
Note: The finger needs to be pressed flatly and placed accurately over the Sensor area.
Improper Positioning of Finger

Vertical (not flat)

Too close to the edge Page 15

Crooked

Too low or high

Cautions
1. Make sure the fingers are clean when using the Fingerprint Scanner. 2. Place the finger correctly. 3. Recommended to use the index, middle or little fingers for Registration. 4. Please avoid using the thumb and pinky fingers, because these two are clumsy when pressing on the
Semsor Area.

Page 16

Suggestions
1. Please keep the sensor away from dust. 2. Please use adhesive tape to clean the Sensor area.
Do not use water or other detergents, which may damage the sensor. 3. Please use a wool-free cloth to wipe the Sensor area. 4. Please make sure the Sensor area is clean after each use.
Possible Complications Some issues may cause difficulties to recognize the Registered fingers or during new Registration. They are:
1. Smoothed out fingers; 2. Too many wrinkles on fingers; 3. Layer of any material on fingers; 4. Extremely dry and wet fingers.
Page 17

Solutions
1. If the user experiences any difficulty during Registration, they can either delete the fingerprint and re-register or can try using any other fingers.
2. It is recommended to choose the suitable finger with fewer wrinkles, no peeling, and clean finger for Registration.
3. Always try to maximize the Contact Area of the finger. 4. Armatura suggests registering alternative Fingerprints. 5. Soaked alcohol cotton is used for cleansing if the fingers are dry, and a clean napkin is used for cleansing if
the fingers are wet.
