1.2 How to turn on and off
Refer to the figure in section 1.1 to locate the SCAN and DOWN buttons.
Note: The trigger on the Ring Scanner and Finger Trigger Glove work as SCAN buttons.

b) The KDC will beep when it is turned ON.
c) Press and hold the SCAN + DOWN buttons simultaneously for 3 seconds again to turn off
the KDC.
Pairing (Bluetooth or NFC)
Connecting your KDC using Bluetooth is made easy with the below pairing barcodes.
If using an Android device, pairing via NFC is even easier: just approaching the KDC to the back of the host
device’s NFC area is enough for pairing. For more details, see section 2.3
2.1 Bluetooth Profiles Explained
a. HID Profile: Allows one-way Bluetooth communication with an Android or iOS host
device. The KDC only transmits data to the host device.
b. SPP Profile: Allows two-way Bluetooth communication. The KDC transmits data to the
host device and the host device can transmit data back to the KDC.
c. HID Windows Profile: Allows one-way Bluetooth communication with Windows host
device. The KDC only transmits data to the host device.
Note:HID inputs data directly into an application. SPP requires the KOAMTAC SDK to
input data into an application. To gain access to the SDK, please complete the form here:

Bluetooth profile. If you are unsure which Bluetooth profile is right for you, please refer
to Chapter section 2.1.
•If you use an Android, iOS, or Mac device and desire an HID connection, then scan
barcode #1 above.
•If you use a Windows device and desire an HID connection, then scan barcode #2
above.
•If you desire an SPP connection for any device, then scan barcode #3 above.
c. In HID or HID Windows Profile, check the list of available Bluetooth devices on your host
device. From the list, select the KDC80 listed by serial number in brackets that matches
the serial number found on the back side of the KDC80. KDC80 will beep upon
connection and display “Bluetooth Connected” on its screen. Now it is ready to use.
