How do I turn the blocks on and off?

To turn a block on, press and hold the circular power button (just above the SAM logo on the rubber casing) for about 2 seconds until the light turns red. Once it’s red, the block is ready to connect via Bluetooth.

To turn a block off, press and hold the power button again, or simply leave it unused—after a few minutes of inactivity, it will go into sleep mode. If you close SAM Studio, the blocks will also unpair and power off automatically after about 30 seconds.
