Common Problems


1. When using a rechargeable lithium battery with poor performance, its voltage reduction circuit will interfere with the performance of the receiver.

2. When multiple sets of equipment are used at the same time, if the frequency point is set improperly, it is easy to cause performance degradation due to intermodulation interference.


Notes


  1. This model of product is recommended to be used with the iweex® brand, the same technology platform, and the model is DTR22X ("X" is any number) receiver device.

  2. Please use batteries from regular manufacturers with qualified products! Counterfeit batteries may cause leakage or even explosion. If any abnormality is found in the battery, please stop the equipment immediately and replace it to avoid the risk of explosion or damage to the equipment!
