Troubleshooting

This section will help you solve minor problems that could occur during the operation 
of your TomoScan FOCUS LT. Olympus has developed this troubleshooting guide 
assuming that the instrument has not been modified, and that the cables and 
connectors are those provided and suggested by Olympus.

Table 4  Troubleshooting guide 

Problem

Cause

Solution

The instrument does 
not turn on.

The fuse is blown.

Verify the fuse and replace it, if 
applicable, with a fuse of the 
correct rating. For the detailed 
procedure, see “Fuse Changing” 
on page 38.

Communication 
problems occur 
between the 
computer and the 
TomoScan 
FOCUS LT.

The workstation and 
the TomoScan 
FOCUS LT

 

are not 

connected with the 
proper Ethernet cable 
type.

Ensure that you use a crossover 
Ethernet cable for a direct 
connection between the 
workstation and the TomoScan 
FOCUS LT.
