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.
If there is no sound from the unit or no sound when connected to an external device
Make sure the adapter on the receiver is well connected to your device. Or remove the
adapter and wipe the charging contacts with a clean cloth.
Make sure the mic gain is not turned to minimum.
Make sure the unit is not muted.
If the sound of the unit is too low or too loud or even distorted
Adjust mic gain to the suitable level for recording in the current environment to improve the
recording effect.
Current noise or other abnormal noise appears during monitoring
Make sure there is no interference near the unit. If the noise still exists after changing the
unit's position, please contact our customer service.

Make sure there is no interference between the transmitter and receiver. If the intermittent
sound still occurs frequently, please contact our customer service.
Howling noise occurs when using the receiver with an adapter
Make sure your phone's speaker is disabled in the receiver's menu.
Failed to charge the transmitter(s) or receiver via the charging case

charging box to check whether it is in a charging state. If the transmitter(s) or the receiver is
still failed to be charged, please contact our customer service.
