• Shot switch:
- Press the Shot switch to start the selected curing
program.
- Press the Shot switch during operation to stop the
program in progress.
5.3. Mode selection
• 3K Mode / Ortho Mode: When selected, the LED
display turns to ORANGE color. The output will be 3000
mW/cm².
•
Standard Mode:
When selected, the LED display turns
to GREEN color. The output will be 1600 mW/cm².
Press and hold the Mode switch for 3 seconds to change
curing mode (GREEN and ORANGE light changes alternately).
5.4. Polymerization time setting
•
3K / Ortho Mode:
Quickly press the Mode switch
sequentially on ORANGE light to toggle the light through
the 4 time settings
(1sec. - 2sec - 3sec. - Ortho Mode).
Ortho Mode (Orange) Recommended for curing a full arch of
orthodontic brackets, or 16 brackets total. When activated, the
light will cure for approximately 3 seconds for each mesial or
distal side. A visual half-second blink and an audible beep will
indicate when each bracket side has been cured.

5.5. Composite Curing Test Block Instructions
For Use
Manufacturer’s recommended composite curing times are typi-
cally based on curing 2mm increments with a minimum accept-
able visible light output of 300 mW/cm
2
. For curing lights that
provide significantly higher output, the test block enables the
user to evaluate high power curing and adjust either the time or
increment thickness based on the results. In general, the required
curing energy is a constant function of the light output and time
(mW/cm
2
x sec). Changes in one factor can be offset by adjusting
the other. As an example, doubling the light output (mW/cm
2
)
may reduce the curing time (sec) by half. This relationship can
be used as a guideline for establishing composite curing test
parameters.
The test block is used to determine the curing rate at varying
thickness, of a selected combination of composite material and
curing light. To use the test block:
1. Place the block on a mixing pad or similar smooth
surface, test (bottom) side down.
2. Fill a selected opening (typically the 2 mm deep hole),
flush to the top surface, with the composite to be tested.
