What is the battery status of the Microphone Kit?

During use, the battery of the Microphone Kit slowly runs out. It is good to be aware of
this, so that you can recognize in time when the Microphone Kit needs to be charged.
The average operating time for each microphone is 4 hours. This means a 100% full battery allows you to have a 4-hour conversation until the microphone switches off.

Full:
As long as the lights are green during use, the Microphone Kit is sufficiently charged.

Almost empty:
If the battery is low, the light will alternately flash green and red.

Battery too low to use:
In case no charging action is taken, the Microphone Kit will automatically switch off. This is indicated by the light(s) flashing red 10 times.
