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.
