Does Wicked Mouse PLUS have an alert function?

Yes. When the battery is low or it gets completely stuck during operation for over 10 minutes, Wicked Mouse PLUS will emit a regular "beep-beep" sound. You can check its status via the color of the taillight strip:

• Red – Needs charging;
• Yellow – Completely stuck. To resolve this, you can either touch the toy, power it off, or it will automatically restart after 30 minutes.
