6. メンテナンス

To ensure the longevity and optimal performance of your ZIOCOM BT5804 Bluetooth Transmitter, follow these maintenance guidelines:

• クリーニング： デバイスのクリーニングには、柔らかく乾いた布をご使用ください。液体クリーナーや溶剤は表面や内部部品を損傷する可能性があるため、使用しないでください。
• ストレージ： デバイスは、直射日光、極端な温度、高湿度を避け、涼しく乾燥した場所に保管してください。
• 取り扱い： デバイスは丁寧に取り扱ってください。落としたり、強い衝撃を与えたりしないでください。
• 環境： Do not expose the device to water or other liquids. Keep it away from heat sources and open flames.

7。 トラブルシューティング

If you encounter issues with your ZIOCOM BT5804, please refer to the following common problems and solutions:

• No Audio After Successful Pairing:
          If connecting via optical cable, ensure your TV's audio output format is set to PCM/ステレオ. Different TVs may have varying settings for this. Check your TV's audio settings menu.
• Audio Delay/Lag (Even with aptX Low Latency):
          For aptX Low Latency (aptX-LL) to function correctly and eliminate audio delays, both the ZIOCOM BT5804 transmitter and your Bluetooth headphones/speaker must support aptX-LL. If your receiving device does not support aptX-LL, you may still experience some audio-video synchronization delay.
• Connection Issues or Short Range:
          The 30-meter range is an optimal value. Physical obstructions (walls, furniture) and wireless interference (Wi-Fi routers, other Bluetooth devices) can reduce the effective transmission distance. Try moving the transmitter and receiving device closer or away from potential interference sources.
• デバイスの電源が入っていない:
          Ensure the USB power cable is securely connected to both the transmitter and a functional 5V USB power source. The product does not include a power adapter; use a standard 5V USB adapter.
