If you're having trouble with your Gemini Bluetooth speaker, there are a few things you can try to reset it. First, make sure that the batteries are properly charged. If they are, then try turning off the speaker and then back on again. If that doesn't work, try unplugging the speaker from its power source for a few seconds and then plugging it back in. Finally, if none of these things work, you can try resetting the speaker by pressing and holding down the power button for about 10 seconds.
