Troubleshooting

If you encounter problems when using the unit, please refer to the following checklist before contacting technical support. If the problem cannot be solved, please contact the dealer’s after-sales service department.

No sound

Operating range is limited, sound changes, or noise appears

1. Make sure there is no interference from high-power wireless routers or devices in your recording environment. If the recording environment can’t be changed, you need to find the best distance and angle to record.
2. Due to 2.4GHz wireless frequency, signal can be easily attenuated. Please try to avoid obstacles, such as walls and buildings, and avoid close proximity to devices with 2.4GHz signal, such as high-power Wi-Fi antennas, radios, etc.
3. Make sure the receiver is well connected to your device properly.
