  1. The LCD displays of ST may occasionally blur when they are used for hours at over 40℃ ambient operating temperature. This is a temporary phenomenon. After the temperature returns to normal, the normal display will be restored. The ST's operation will not be affected even though the display is blurred.
  2. The degree of protection provided by these products is equivalent to IP65f, however their performance cannot be guaranteed for every environment. Be sure to confirm your work environment requirements prior to installation.
