2.1. 433MHz Wireless Connection
This method provides an extended transmission range, ideal for large spaces like warehouses.
- Plug the 433MHz long-range receiver (integrated into the charging base) into a USB port on your computer or host device.
- The scanner should automatically pair with the receiver. If not, refer to the "Pairing" section in the operating guide.
- The outdoor transmission distance can reach up to 984 feet (300 meters) in open line of sight.
2.2. Bluetooth veza
Bluetooth allows seamless integration with smartphones, tablets, and laptops.
- Provjerite je li skener uključen.
- Activate Bluetooth on your host device (e.g., smartphone, tablet, laptop).
- Traži available Bluetooth devices and select "Symcode MJ-2021R" (or similar name) from the list.
- Pratite sve upite na ekranu da dovršite proces uparivanja.
