3.3 Offline Storage Mode
When operating in 2.4G wireless mode and the scanner moves beyond the receiver's range, it automatically enters offline storage mode. In this mode, scanned barcode data is stored internally in the scanner's FLASH memory. Once the scanner returns within range, the stored data can be uploaded to the host device.
To upload stored data, scan the "Upload Data" configuration barcode (refer to the separate configuration guide for specific barcodes).
4. Priežiūra
4.1 Skaitytuvo valymas
To ensure optimal performance, keep the scanner clean.
