Why does my Myndr Switch beep?

Sometimes the Myndr Switch makes beeping sounds. What do those beeps actually mean?

Below is an overview of what the different tone combinations mean:

Sound	Meaning	Action
Rising "jingle"	The switch has started up and is ready for use
Two short tones: mid-high	The changed mode has been sent
Two short tones: mid-low	Sending the changed mode failed	Replace the batteries with a new pair of high-quality AA batteries
Three long, low tones	The batteries are too weak to send anything	Replace the batteries with a new pair of high-quality AA batteries

What the beeps mean depends on how many beeps there are and whether they are short (a fraction of a second) or long (one second).

1 short beep
The Myndr Switch is starting up.

2 short beeps
Sending the mode failed. The switch will try again a few more times by itself.

3 short beeps
The batteries are too weak. It is best to replace them with new ones. Make sure you use the recommended batteries.

3 long beeps
Sending the mode is not working. Replace the batteries with new ones and try again. Make sure you use the recommended batteries.
