KERR will, upon request, make available circuit diagrams, part lists, calibration
instructions and other information which will aid appropriately qualified technical
personnel to repair parts of the equipment classified as repairable.
SERVICE PROCEDURE
1. See Section 9, OPERATION, item
l, RADIOMETER for service
procedure.
2. Unit must be shut off immediately
and returned for repair.
3a. Check to make sure power switch
located on control unit is in "ON"
position and 5 second "activate"
time has elapsed.
3b. Check power cord connections
both at unit and at AC outlet
(Mains) to be sure they are
properly seated. Check primary
fuses located in the back of the
unit (see Section 5, FUSE
REPLACEMENT).
•
If fuses are blown, a larger
problem is often indicated.
problems recur with new fuses,
return entire unit for repair.
3c. Try another power outlet.
4a. Check the lamp to be sure it is
properly seated. If OK, then,
4b. Replace the lamp. (See Section 4,
LAMP REPLACEMENT).
4c. Unit may have overheated due to
very extended operation.
•
Wait for unit to cool down. Lamp
will respond to switch activation.

•
Use enclosed Hardness Disk to determine curing time.
•
Do not place light directly on or towards unprotected gingiva or skin.
•
Adjust your curing techniques in accordance with the increase in
curing energy. Some examples are; decrease curing time, increase
composite thickness, increase distance between light guide end and
light cured materials.
