Úsáid an lasc TX/RX ar thaobh na feiste chun an modh oibriúcháin atá uait a roghnú:
- Mód TX (Tarchuradóir): To send audio wirelessly from a non-Bluetooth device (e.g., TV, PC) to Bluetooth headphones or speakers.
- Mód RX (Glacadóra): To receive audio wirelessly from a Bluetooth device (e.g., smartphone, tablet) and play it through a non-Bluetooth audio system (e.g., car stereo, wired speakers).
3.3 Pairing in RX (Receiver) Mode
Follow these steps to connect the device as a receiver:
- Athraigh an gléas go RX mód.
- Insert the 3.5mm audio jack into the auxiliary input of your non-Bluetooth audio system (e.g., car stereo, wired speaker).
- Press and hold the multi-function button for approximately 3 seconds until the LED indicator flashes, indicating pairing mode.
- On your Bluetooth-enabled device (e.g., smartphone), enable Bluetooth, search for available devices, and select "BT-18" to connect.
- Nuair a bheidh sé ceangailte, stopfaidh an táscaire LED ag splancadh agus fanfaidh sé soladach.

6. Fabhtcheartú
If you encounter issues with your device, refer to the following troubleshooting tips:
| Fadhb | Cúis Féideartha | Réiteach |
|---|---|---|
| Ní chuireann an gléas cumhacht ar. | Ceallraí íseal. | Muirear an gléas go hiomlán. |
| Ní féidir péireáil le gléas Bluetooth. | Incorrect mode selected; device not in pairing mode; receiving device too far or not in pairing mode. | Ensure correct TX/RX mode. Press and hold multi-function button for 3 seconds to enter pairing mode. Ensure receiving device is in pairing mode and within 10m range. |
| Gan fuaim nó droch-chaighdeán fuaime. | Incorrect cable connection; volume too low; interference; incompatible codec. | Check 3.5mm cable connection. Adjust volume on both devices. Move away from sources of interference. Ensure devices support SBC/AAC. |
| Audio delay/latency. | Bluetooth technology inherent latency; codec limitations. | While Bluetooth 5.2 reduces latency, some delay may still occur, especially with certain codecs or older receiving devices. This is often an inherent characteristic of wireless audio transmission. |
| Tá saolré na ceallraí níos giorra ná mar a bhíothas ag súil. | High volume usage; frequent pairing/disconnection; aging battery. | Reduce volume. Ensure full charge before use. Battery performance may degrade over time. |
| Cable is too short for my setup. | Standard cable length. | Smaoinigh ar cheannachasing a longer 3.5mm audio extension cable if needed for your specific setup. |
