2. Ijikọ ihe nyocha

The MJ-2021R offers two primary connection methods: 433MHz wireless via its receiver and Bluetooth.

2.1. 433MHz Wireless Connection

This method provides an extended transmission range, ideal for large spaces like warehouses.

1. Plug the 433MHz long-range receiver (integrated into the charging base) into a USB port on your computer or host device.
2. The scanner should automatically pair with the receiver. If not, refer to the "Pairing" section in the operating guide.
3. The outdoor transmission distance can reach up to 984 feet (300 meters) in open line of sight.

2.2. Njikọ Bluetooth

Bluetooth allows seamless integration with smartphones, tablets, and laptops.

1. Ensure the scanner is powered on.
2. Activate Bluetooth on your host device (e.g., smartphone, tablet, laptop).
3. Chọọ maka available Bluetooth devices and select "Symcode MJ-2021R" (or similar name) from the list.
