3.1 Important Note on S ignal and P ower C ables
The signal and power cables connected to the modules are not
designed to be used as lanyards to hold the modules in place
when unlatched from the display face.
When performing maintenance on the display face,
Daktronics recommends removing the modules completely
from the display face to avoid possible damage.
If module removal is not possible, use the safety lanyards —
provided in the spare parts box or installation kit — to hang
modules from the display face. Refer to Figure 3 for an
example of module damage caused by using a SATA cable as
a lanyard.
