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. See Section D for dip-
switch details.
