2. Scanning 2D and Mobile Barcodes
The SC402BT is capable of reading various 2D barcodes and barcodes displayed on mobile phone screens, including coupons, mobile tickets, and digital wallets. For optimal performance when scanning from screens, ensure the screen brightness is adequate and avoid glare.
3. Komunikasi Tanpa Wayar
The scanner maintains a stable wireless connection with the USB receiver up to 100 meters in open areas. Obstacles such as walls or other electronic devices may reduce this range. If the scanner moves out of range, it will store scanned data in its internal memory and transmit it once the connection is re-established.
Penyelenggaraan
1. Membersihkan Pengimbas
To ensure optimal scanning performance, keep the scanner's window clean. Use a soft, lint-free cloth lightly dampened with water or a mild, non-abrasive cleaner. Do not use harsh chemicals or abrasive materials, as these can damage the scanning window.
2. Penjagaan Bateri
- Recharge the battery when the low battery indicator is active.
- Elakkan menyahcas sepenuhnya bateri dengan kerap untuk memanjangkan jangka hayatnya.
- Simpan pengimbas di tempat yang sejuk dan kering apabila tidak digunakan untuk tempoh yang lama.
