GC-206BTB: How do I turn the LED light show on or off?
To turn the LED light show on or off on your Gemini Sound GC-206BTB, hold down the MODE/LED SWITCH button on the back of the speaker until the lights turn on or off. Hold the button down again to switch back.
One thing to watch for: if you don't hold the button and instead give it a quick tap, the GC-206BTB switches playback modes instead of toggling the lights.
