How do I ensure that my kid is heard properly?

The microphone on the Noise Explorer smartwatch is very sensitive and comes with high-quality noise-cancelling feature. In normal background noise level conditions, keep the smartwatch 20-30cms away from the mouth to be heard clearly by the receiver. In high background noise level conditions, keep the smartwatch closer to your mouth.

How do I get the best audio output from the Noise Explorer watch's speaker?

The speaker level can be adjusted on the Noise Explorer smartwatch by swiping down from the home screen to reveal the volume level. The holes on the top of the Noise Explorer smartwatch allow audio from the speaker to be heard. But make sure that the holes are not blocked and do not have water in them.
