- Power On: Press and hold the power button on the receiver until the color TFT LCD screen illuminates.
3. Operating Instructions
The receiver features a user-friendly menu design and a clear color TFT LCD screen for intuitive information display.
3.1 Frequency Adjustment
Use the navigation controls on the receiver to access the frequency settings. The receiver bandwidth is 36MHz, with a frequency adjustment step of 25kHz for precise tuning. Select a frequency that matches your S3D transmitter within the supported ranges:
- 560-596MHz
- 640-676MHz
- 863-865MHz
- 902-928MHz
3.2 Audio Settings
The receiver allows for adjustment of audio parameters:
- High Boost: Adjust this setting to enhance high-frequency audio response according to your preference.
- Left and Right Channel Balance: Fine-tune the balance between the left and right audio channels for optimal stereo imaging.
4. Maintenance
- Cleaning: The receiver's aluminum shell is designed to be scratch and wear-resistant. Clean the device with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Battery Care: To prolong battery life, avoid fully discharging the receiver frequently. Recharge the battery when the low battery indicator appears. If storing the device for an extended period, ensure it is partially charged (around 50%) and recharge every few months.
- Storage: Store the receiver in a cool, dry place away from direct sunlight and extreme temperatures.
5. Troubleshooting
- No Sound/Intermittent Audio:
- Ensure the receiver is powered on and fully charged.
- Verify that your earphones are securely plugged into the 3.5mm output.
- Check that the receiver's frequency matches the transmitter's frequency.
- Confirm that the transmitter is powered on and sending a signal.
- Ensure the S3D receiver is not being used with an ANLEON S2/S3 wireless in-ear monitor system, as they are not compatible.
- Short Working Range:
- The typical indoor working range is about 50 meters. Obstacles like walls or large metal objects can reduce this range.
- Ensure the receiver's antenna is unobstructed and properly positioned.
- Check for potential interference from other wireless devices operating on similar frequencies.
- Receiver Not Charging:
- Verify that the Type-C charging cable and power adapter are functioning correctly.
- Ensure the charging port on the receiver is clean and free of debris.
