Step 4. Check the assemblies on the IIC bus by repeating the following steps for each
assembly.
Set the power switch to off ( O ).
Reconnect one assembly at a time in the following order.
A11 Keyboard Controller (cable to A7 P1)
A10 Rear Panel (cable to A10 P100)
A5 Analog
A1/A2 Input (lower slot)
A2 Input (upper slot)
Set the power switch to on ( l ).
After the softkey menu appears, (about one minute after power up) press
any key.
If the analyzer does not respond correctly, the assembly just reconnected is
probably faulty.
Step 5. If the failure still is not isolated, go to page 4-29, ‘’To troubleshoot fast bus
failures.’’
