Periodic Maintenance and Inspection

Cleaning Display Screen

Time periods between cleaning depend upon local conditions and are at the discretion of the operator. This routine cleaning can be carried out in the normal way using a damp and/or dry cloth.

Note: This screen is specially coated to reduce reflections and although this coating is very durable misuse or incorrect cleaning procedures can damage it.

LED Illumination Test Inspection

The purpose of this test is to ensure no LED fails to illuminate and should be checked annually.

Remove the left-hand end cheek and carefully slide out the logic control board so that the dip-switches are accessible. Set switch 8 to ON, inspect the LED display that will run blocks of Green, Red and Yellow across the display. Look for any LEDs that fail to illuminate.

Return switch 8 to the OFF position to stop this test.

LED Matrix Scanning Inspection

The purpose of this inspection is to ensure the LED matrix is being scanned correctly. Remove the left-hand end cheek and carefully slide out the logic control board so that the dip-switches are accessible.

Set switch 7 to ON, Yellow diagonal stripes will run across the display. Check that these stripes are straight and that Yellow is the only colour displayed. Having completed this visual inspection return switch 7 to OFF and ensure that all switch settings comply with system requirements for baud rate and wallboard network address number. See Section D for dip-switch details.
