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 LED's 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 color 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.
