Do not allow the product to maintain contact with the same area of skin for extended
periods of time during use.
This may result in low-temperature contact burns, including skin redness and blistering,
even if the product does not feel hot. The use of a tripod or similar equipment is
recommended when using the product in hot places and for people with circulation problems
or less sensitive skin.
Follow any indications to turn off the product in places where its use is forbidden.
Not doing so may cause other equipment to malfunction due to the effect of electromagnetic
waves and even result in accidents.
