آپريٽنگ موڊس
The device supports three main operational modes:
1. رسيور (RX) موڊ
In RX mode, the device receives wireless audio from your mobile phone, computer, or tablet and outputs it to an existing audio system (e.g., home stereo, speakers) via AUX, Optical, or RCA cables. This mode makes your traditional audio equipment Bluetooth-enabled.
- Set the mode switch to 'RX'.
- Connect the adapter to your audio system (amplifier, mixer, speakers) using the appropriate audio cable (3.5mm AUX, RCA, or Optical).
- اڊاپٽر کي چالو ڪريو.
- Enable Bluetooth on your mobile device (smartphone, tablet, PC) and search for the Opansten adapter.
- Select the adapter from the list of available devices to pair.
- Alternatively, for NFC-enabled phones, place your phone near the NFC area on the adapter for instant pairing (ensure NFC is enabled on your phone).
- Once paired, audio from your mobile device will stream to your connected audio system.

2. ٽرانسميٽر (TX) موڊ
In TX mode, the device transmits audio from non-Bluetooth audio sources (e.g., TV, PC, iPod, CD player) to Bluetooth headphones or speakers.
- Set the mode switch to 'TX'.
- Connect the adapter to your audio source (TV, PC, iPod) using the appropriate audio cable (3.5mm AUX, RCA, or Optical).
- اڊاپٽر کي چالو ڪريو.
- پنهنجا بلوٽوٿ هيڊفون يا اسپيڪر پيئرنگ موڊ ۾ رکو.
- The adapter will automatically search for and connect to nearby Bluetooth audio devices.
- Once connected, audio from your source device will stream wirelessly to your headphones/speakers.

3. بائي پاس موڊ (وائرڊ ڪنيڪشن)
Bypass mode allows you to use the device as a wired pass-through, connecting your audio source directly to your speakers without Bluetooth. This is useful for quickly switching between wired and wireless audio without disconnecting cables.
- Set the mode switch to 'Bypass'.
- Connect your audio source (e.g., TV) to the adapter's input port (AUX or Optical).
- Connect the adapter's output port (AUX or Optical) to your speaker device (e.g., soundbar, ampوierيڪ زنده).
- Audio will pass through the adapter directly to your speakers.
- You can easily switch back to TX or RX mode without unplugging cables.

- جڏهن گهڻي عرصي تائين استعمال ۾ نه هجي ته ڊوائيس کي ٿڌي، سڪل جاءِ تي رکو.
مشڪلاتون
- Difficulty pairing with Sony Bluetooth devices: Sony's Bluetooth headsets/earphones/headphones use a special, non-public encoding method. When pairing with Sony devices in transmitter mode, it may take longer to establish a connection. The pairing time varies by model, but they should eventually pair successfully.
- ڪابه آڊيو يا خراب آڊيو معيار ناهي:
- پڪ ڪريو ته صحيح موڊ (TX/RX) چونڊيو ويو آهي.
- پڪ ڪريو ته سڀئي آڊيو ڪيبل محفوظ طور تي صحيح ان پٽ/آئوٽ پٽ پورٽن سان ڳنڍيل آهن.
- Check the volume levels on both the adapter and the connected audio devices.
- Ensure the connected Bluetooth device (headphones/speakers) is within the operational range (up to 80m/262ft in open air, 30m/100ft indoors).
- Confirm that both the adapter and the connected device support the same audio codec (e.g., AptX HD, AptX LL) for optimal quality and low latency.
- NFC pairing not working: Ensure your mobile phone has NFC enabled and is placed directly over the NFC area on the adapter. NFC pairing is only supported in RX mode.
- ڊوائيس چالو نه آهي: Ensure the device is fully charged. If the battery is low, connect it to a power source using the Micro USB cable.
استعمال ڪندڙن جون صلاحون
- For the best low-latency experience, ensure both your Opansten adapter and your connected Bluetooth headphones or speakers support AptX Low Latency.
- When using NFC for quick pairing, always confirm that your mobile device's NFC function is active and the adapter is set to Receiver (RX) mode.
- To maximize the long-range capability, try to minimize physical obstructions between the adapter and your connected Bluetooth device.
- If you frequently switch between wired and wireless audio, utilize the Bypass mode to avoid constantly plugging and unplugging cables.
