7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from earbuds | Receiver not powered on; low battery; transmitter not powered on; incorrect frequency; earbuds not connected; volume too low. | Ensure receiver and transmitter are powered on. Check receiver batteries. Verify frequency matching via IR sync. Confirm earbuds are securely plugged in. Increase receiver volume. |
| Interference or static | Conflicting frequencies; excessive distance from transmitter; environmental RF noise. | Perform auto-scan on the transmitter to find a clear frequency. Ensure receiver is within the 160ft operating range. Adjust RF power to 'High' if in a large area. Avoid other wireless devices operating on similar frequencies. |
| Distorted audio | Input signal too high; receiver volume too high. | Activate the -12dB PAD switch on the transmitter. Reduce the input level on the transmitter. Lower the volume on the bodypack receiver. |
| Mono signal only in one earbud (when expecting stereo) | Only one input channel connected to the transmitter. | Ensure both Left and Right audio input channels are connected to the transmitter for stereo operation. If a mono source is used, a Y-splitter cable may be required to send the mono signal to both L/R inputs of the transmitter. |
| Settings change accidentally | Lock function not activated. | Activate the lock function on the transmitter after configuring settings (refer to Section 5.4). |
