A:Answer Hello! When the internal temperature of the unit rises during use, a message will be displayed. When this happens, the unit will turn off automatically a few minutes later. Wait until the temperature has dropped before resuming use. In certain situations, continuous use could cause the unit to overheat and cause a malfunction. Such use is strongly discouraged. If you require further assistance, please contact the Support Team via Live Chat on the Panasonic Website, Contact Us option, Mon-Fri, 9am-5pm EST. -C
