Using your Audo Ignus H20 Flameless Candle is super easy. First, make sure to insert the batteries as indicated. Once the batteries are in, you can turn on the candle. You can adjust the brightness to one of the three settings according to your mood. For a cozy reading nook, choose a lower setting. If you're having a party, go for the highest setting. When it comes to maintenance, keep the candle clean by gently wiping it with a soft, dry cloth. Avoid using any harsh chemicals or abrasive materials as they might damage the matte finish of the bone china. Store the candle in a cool, dry place when not in use. If you want to return the product, just make sure it's within 30 days of purchase and in its original condition.
