I practiced Yoga on my mat and it stopped to warm, please, advice how to reload the controller.

It appears that the internal sensors or bimetal switches may have been damaged, and the mat will likely need repair. Amethyst mats are wonderful for relaxation and meditation, but if you plan to use one for active training, we recommend purchasing our unpowered mat instead — it is much less expensive and designed for that type of use.

Please contact us so we can arrange repair or replacement.

To help prevent damage in the future, please follow these precautions:

• Never fold the mat while it is hot, and never heat it while folded.
• Avoid walking on the mat, exercising on it, or placing heavy objects on top, as this can damage the internal sensors and heating system.
• When storing, always fold the mat the same way it arrived — with the crystal surface on the inside. Folding it the opposite direction can cause damage.

Although the mat may look firm and strong, there are many delicate internal components that require careful handling. The best way to use it is on a flat surface while lying down. Gentle, careful use will help ensure long-lasting performance.
