3. Skaitytuvo susiejimas su imtuvu
The scanner and receiver are typically pre-paired. If pairing is lost or you are connecting a new scanner to an existing receiver, follow these steps:
- Ensure the USB receiver is plugged into your computer.
- Įjunkite brūkšninių kodų skaitytuvą.
- Scan the specific pairing barcode provided in the quick start guide or on a dedicated pairing card (if applicable). Refer to your product's specific pairing barcode for successful connection.
- A successful pairing will be indicated by an audible beep from the scanner and/or a change in the indicator light status.
Note: One receiver can support up to 99 scanners, making it suitable for multi-scanner environments.
Skaitytuvo valdymas
1. Basic Scanning Operation
Norėdami nuskaityti brūkšninį kodą:
- Nukreipkite skaitytuvo langelį į brūkšninį kodą, kurį norite nuskaityti.
- Press and hold the trigger button. A red aiming line or illumination will appear.
- Position the aiming line across the entire barcode.
- Once the barcode is successfully read, the scanner will emit a beep and the data will be transmitted to your connected device.

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. Belaidis ryšys
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.
Priežiūra
1. Skaitytuvo valymas
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. Akumuliatoriaus priežiūra
- Recharge the battery when the low battery indicator is active.
- Kad pailgintumėte akumuliatoriaus tarnavimo laiką, venkite jo dažnai visiškai iškrauti.
- Kai ilgesnį laiką nenaudojate skaitytuvo, laikykite jį vėsioje, sausoje vietoje.
Trikčių šalinimas
| Problema | Galima priežastis | Sprendimas |
|---|---|---|
| Skaitytuvas neskaito brūkšninių kodų. | Barcode damaged or poorly printed; scanning window dirty; scanner out of range; scanner not paired. | Try scanning a different barcode; clean the scanning window; move closer to the receiver; re-pair the scanner. |
| Į kompiuterį duomenys neperduodami. | USB receiver not properly connected; scanner not paired; software issue on host device. | Ensure receiver is firmly plugged in; re-pair scanner; check host device's input settings or restart application. |
| Skaitytuvas neįsijungia. | Baterija išsikrovusi arba jos įkrova maža. | Visiškai įkraukite skaitytuvą. |
