Setup guide

2.4G receiver / Bluetooth BLE-HID / USB
Manual V22-(2.4+LY)

Scan only the setting you need. Use your scanner, not your phone camera. Codes are alternatives unless a sequence is stated.
Save to your phone: open a group image, then touch and hold to save it. Enlarge the image or print it if a code is difficult to scan.

Bluetooth and 2.4G pairing

Choose the connection you use. BLE-HID is keyboard pairing; BLE passthrough requires compatible software and is not SPP. Holding the button for 18 seconds switches between BLE-HID and the receiver.
