Took me awhile but I found out how to re-pair a previously connected remote control for the Hisense Pulse using BlueTooth. Lucky enough I still have the original manuals. I've included the a picture of the manual with the step-by-step guide. Overall to reconnect the remote press and hold the "OK" and "A" (coloured red) buttons, go to the Network/Bluetooth and select the previously connected remote (if not there select new). Enjoy!
