12.Key pair code can support multiple groups of non-interfering parallel work at the same time.
13.Multiple
candidate frequency bands, easy to avoid interference frequency: This
product works in 2.4GHz ISM (ie industrial, scientific, medical)
frequency band, with 16 selectable frequency points to meet
multi-frequency and frequency hopping needs; to avoid In the 2.4GHz
public frequency band, the influence of the interference on the sound
quality, the product provides the frequency selection function. If the
product has strong noise during the working process, that is, when the
interference occurs at the current frequency, the output sound quality
is affected. New working frequency points can be selected to keep the
product in good working condition.
