4. Replace the fuse with a fuse of the correct rating as indicated in Table 3 on
page 39.
Use only 250 V slow-blow fuses that meet IEC 127 standards. Using fuses that are not
recommended could cause a fire hazard.
5. Reinsert the fuse holder.
The fuse is now replaced, and the TomoScan FOCUS LT should be ready for
operation. If the instrument still does not operate after the fuse replacement, refer
to a qualified technician.
To ensure that you have a spare fuse of the correct rating on hand, always keep a
spare fuse in the fuse holder (see Figure 4-3 on page 40).
