Note(1) 90%RH maximum humidity, 60℃ maximum wet-bulb temperature (2) When operated at a temperature lower than 0℃, the LCD worked slowly and the screen appeared low-contrast images due to the characteristics of LC(Liquid Crystal). (3) If any fixed pattern is displayed on LCD for minutes, image-sticking phenomenon may occur.
