First-Aid in the Event of Malfunction

Error functions can sometimes have trivial causes; however, they

can also sometimes be complex in nature and require costly

analysis.

General guidance

Note

The regular running of the Windows® programs “De-

frag” and “Scandisk” on the PC can remove sources of

error and raise system performance.

Check Connections and Cables

Start with a careful visual check of all cable links. If the LCD’s are

not working, make sure that the power is reaching the computer

and all peripherals.

Note

Switch off the computer and check all cable links. If

the computer is connected to peripherals, check also

the plug connections of all cables. Do not arbitrarily

swap the cables between various units, even if they

appear to be precisely the same. The pin assignments

of the cables are likely to be different. Once you have

ascertained that the power supply is not at fault and

all connections are intact, switch on the computer

again.
