the display does not come in contact with metal objects or other
hard objects, as it might cause scratching or damage. Also, be
careful not to scratch or damage the display by using an object
whose metal or other hard part comes in contact with the display.
● When suddenly brought into a warm place from a cold place,
or when in a humid location, or when used where temperature
suddenly changes, water droplets (i.e. condensation) sometimes
are formed inside the product. Note that when used under
conditions such as this, humidity might cause a fault.
