Plug the Fire TV Stick into the HDMI port on the TV and plug the power cord into a wall outlet.
Some TVs might come with a USB port. It may be tempting to use that to power your Fire TV Stick, but Amazon does not recommend this since the USB port on the TV most likely won’t provide enough power to the device, resulting in performance issues.
It is recommended that you enable the “Parental Controls” when prompted. This will prevent unwanted use of the Fire TV Stick if the remote falls into the wrong hands.
Once finished with setup, go to the search. On the Fire TV remote, click the left arrow and then “select” (middle button).
Search for “Markey” and select the “Markey Digital Signage” app.
Download the app. Once downloaded, the screen will display a device key.
Log onto https://my.markeyds.com/ from your computer and register the new device by entering the device key and select a display for this device.
