The Scan2 and RC Pro2 remain connected even if the Scan2 battery is replaced.
Once the Scan2 wearable barcode scanner powers back up, you’ll hear a sound on the Rufus Cuff/Rufus Cuff Pro that will confirm it is paired to that Scan Glove 2.There will also be an on screen message that says scanner reconnected successfully. You can always test scanning a barcode into a text field to ensure the scanner is connected.
