What are the safe storage conditions for the XH2164-001 sewing machine?

Do not store the machine in locations exposed to extremely high or low temperatures, extreme temperature changes, high humidity or steam, near a flame or heater, outdoors or in direct sunlight, or in extremely dusty or oily environments. Storing the machine in these conditions may cause damage such as rust from condensation. Additionally, in order to extend the life of the machine, periodically turn it on and use it, as extended storage without use may reduce efficiency. (Page 2)
