TROUBLESHOOTING
If the transilluminator does not yield satisfactory results, follow the
procedures below before attempting to service the unit:
a. Review and comply with the instructions in the Operation section.
b. Check that the transilluminator is connected to a power source
and that the on/off switch or timer knob is positioned correctly.
c. Check that the fuse is operating properly. Use needlenose pliers
to remove the fuse drawer from the power entry unit. There is an
extra fuse in the 120V unit. Remove and discard the spent fuse
and replace it with the spare. The 230V unit has two active fuses
and a filter. Both fuses must be replaced. Use metric fuses for both
the 120V (2.5A F) and 230V (1.5A F) units.
If these steps do not yield satisfactory results, refer to the following
chart:
