How to connect a mobile phone to the printer?

 Search "FlashLabel Pro" on App Store or Google Play to get the App or scan the QR code below to download. 

You need to turn on the Bluetooth on your mobile phone when connecting "FlashLabel Pro" App to the printer. 

Tips: Do not directly pair with the Y42BT in your mobile phone's Bluetooth settings. Otherwise, it will show that it cannot be connected.

If you've already paired the Y42BT directly through your phone system's Bluetooth settings, please unpair and delete it first.

Enter the connection page, select the correct Bluetooth device. 
Note: A "Bluetooth Connection Successful" pop-up notification will appear in the App after successfully connecting to the printer. Currently, the printer's status light is still blue.
