6.2 Residual heat warning (HOT)
In order to prevent burns from the hotplate, the digital hotplate has a residual heat warning
function. When the heating function is switched off and the heating plate temperature is still above
50°C, “Hot” will flash on the LED screen to warn that there is a hazard of burns from the hotplate.
When the unit is powered off, the LED screen alternates the temperature of the hotplate and “Hot”.
When the hotplate temperature drops to below 50°C, the unit will automatically switch off. If users
want to turn off the LED immediately, just pull out the plug directly. When the plug is pulled out, the
residual heat warning function stops running.
