5. 문제 해결
If you encounter issues with your SIMOLIO SM-824D2 headphones, please refer to the common problems and solutions below. For more detailed assistance, consult the 문제 해결 가이드(PDF) or 사용 설명서 (PDF) provided by SIMOLIO.
일반적인 문제 및 해결책:
- 소리가 나지 않거나 볼륨이 낮음:
- Ensure the TV volume is turned up to a sufficient level (30-40%) to provide a strong signal to the transmitter.
- Check the volume level on the headphones themselves and adjust as needed.
- Verify that the correct audio output is selected on your TV (e.g., Optical, RCA, AUX).
- Confirm that the TONE and MONO/STEREO switches on the back of the transmitter base are set correctly. We recommend TONE set to 'Dialog Clear' and MONO/STEREO set to 'MONO' for initial setup.
- Audio Delay/Lip-Sync Issues:
- The 2.4GHz technology is designed for no audio delay. Ensure your TV's audio output is set to PCM if using optical, as some TV settings (like Dolby Digital) can introduce delay.
- Intermittent Sound or Signal Loss:
- Ensure the transmitter is within the effective range (up to 164 feet) and not obstructed by dense materials.
- Check battery level of the headphones and replace with the spare battery if low.
- 헤드폰이 충전되지 않음:
- Ensure the headphones are correctly seated on the charging pins of the transmitter base.
- Verify the power adapter is securely connected to the base and a working power outlet.
