TESTING SYSTEM FUNCTION
1. Normal Operation
After installation is complete, all the system’s components need to be tested.
Apply power to the system and observe the following signs of normal operation:
• The green SilenTouch
™
LED is lit on
the 980.
• The green Power LEDs on the switching
modules and the 980 are slowly blinking.
• The red 980 Low Voltage LED is not lit,
or is very dim.
Note: If the Low Voltage LED is brightly lit, your
system will not function. Check the output
voltage of your power supply and contact Audio
Authority Technical Support.
• For the moment, ignore the color of
the clear LED “Bus Monitor“ on the
980. Later, when product selections
are made, you will notice that the Bus
Monitor LED flickers and is an orange
color. This orange flicker is normal. It
merely indicates that “traffic” is present on the bus.
2. 903 Test Sequence
Test the Control Panel (if your system does not have a 903 Control Panel,
skip to step “3” and ignore other references to control panels.) Reboot
the system (press Secure, 88, Secure) and observe the following test
results on the Control Panel. If you encounter any problems, keep a note
pad handy to record results as they are reported in the Control Panel
windows.
1. All display segments and indicators on the control panel are lit briefly
(lamp test).
2. The Info Display at the left of the panel shows software version
(e.g., 3.4).
3. A System Bus Test is performed.
a. If the word “bUS” flashes in the Info display, it indicates a
problem with a system bus cable or switching module.
b. To find the faulty cable or module, use this process of
elimination: carefully unplug portions of the yellow-red-blue-
black system bus cable to isolate them from the 980 module,
then press any key on the control panel. If “bUS” still appears
on the Info Display, plug the cable back in and try a
different cable.
c. If “bUS” disappears from the Info Display, you have isolated the module or bus cable that is faulty.
Re-address the module and cycle power or replace the cable.
