Why do I fail to connect the Bluetooth?

Reason ①: Unprepared printer 

Please turn on the printer and wait for it to finish the initializing process until you hear consecutive 3 beeps, then connect the Bluetooth. 

Reason ②: For Mac and Chromebook

Bluetooth does not support MacOs or Chrome OS, please use the USB cable to connect.

Reason ③: For Windows

(1) Check if your computer supports the Bluetooth function

(2) The driver hasn’t been installed successfully 

Remove the driver and the "BY-482BT" in the device list, and reinstall the driver via Bluetooth again.

Reason ④: For Smartphones

Please make sure the “Bluetooth Button” on your smartphone is on, and “Location Service” and “Tracking” is on
