Open your QR code scanner app
Most devices have one built into the camera app. If not, download a free QR code scanning app.
Why this helps? The scanner translates the QR code into readable text, including your recorder’s details.
Point your camera at the QR code label
The label is on top of your recorder and will give you a long string of text that consists of: UID, MAC Address, and a random number. Here's an example below:
ABCDEFGHIJKLMNOP111A,bc51fe112233,90
In this example, you have to tap the text to see everything. If you don't know what to get, the MAC address is the one after '111A' that is 12-characters long (that's the highlighted text in the example above).
