2.4 Cooling Fans
Four (4) thermostatically controlled cooling fans are provided to cool the rear of the display. The
thermostat is set to turn the fans on when the video board temperature reaches 30° C. If the display
is used in direct sunlight, airflow must be directed across the front of the display or the display LCD
fluid may reach its clearing point, then the LC1200R will become temporarily unreadable.
2.5 Connectors
There are four connectors supplied as an integral part of the LC1200R.
