B. Measuring the Light's Effectiveness
To ensure complete polymerization at all times, it is critical
to periodically test the light intensity output.
C. Radiometer Display
A reading of 300 mW/cm
output is acceptable for the polymerization of material up
to a 2.0 mm depth. Follow the dental material manufacturer's
instructions for recommended exposure time, and check
using the supplied test block.
A reading below 300 mW/cm
the light output in comparison to the original value, indicates
that corrective action should be taken.
(See Section VII, D Troubleshooting.)
V. INDICATORS
A. Ready Mode
When the unit is charged and ready for use the handpiece
indicator will light green.
B. Sleep Mode
If the handpiece is left out of the charger base for more than
15 minutes the unit will enter sleep mode. During sleep mode
the handpiece indicator light will not be lit. Activating the unit
or placing the unit into the charger base will wake it from sleep
mode. If the indicator light is not lit, and the unit does not
respond to On/Off button presses, the battery may need to be
charged. Place the unit into the charger base and check that the
charger base indicator light turns red. If the light does not turn
red see section VII. Troubleshooting.
C. Thermal Protection Mode
®
The Coltolux LED incorporates thermal protection circuitry
designed to inactivate the unit if operating temperatures become
too high. If this happens, the handpiece indicator light will turn
red until the unit cools. Once the handpiece has sufficiently
cooled (approximately 10 minutes) the indicator light will return
to green indicating the unit is ready for use. If the indicator light
does not return to green within 20 minutes contact your dealer
or Coltène/Whaledent Inc. for service.
If a problem with the unit is suspected, the following functionality
test should be used to determine if there is an issue with your
®
Coltolux LED Curing Light:
1. Fully charge the unit.
2. Activate the unit allowing it to complete the
entire 20 second cycle.
3. Repeat step 2 immediately. Continue until the unit
will no longer activate.
The unit should be able to perform a minimum of 18 complete
twenty-second cycles before it enters thermal protection mode.
If this is the case, the unit is operating as designed and meets
Coltène/Whaledent Inc.'s test specifications.
To reinforce confidence in the LED's operation, always test
restorative materials utilizing the provided Test Block (P/N: 09890).
Only by testing materials with the test block can true depth of
cure and necessary curing times be determined.
D. Low Battery
When the unit's battery has reached a low level the handpiece
indicator light will blink green. The unit may still activate once it
has reached the low battery state, however, few activation cycles
remain and it is recommended the unit is placed on the charger
to fully recharge the battery.
If the unit detects a low battery condition while in thermal
protection mode the handpiece indicator will blink red. Once the
unit has sufficiently cooled the indicator may return to blinking
green and, depending on remaining battery charge, the unit may
still activate, however, few activation cycles remain and it is

recommended the unit is placed on the charger to fully recharge
the battery.
E. Fault Mode
If a fault is detected by the unit the handpiece indicator will turn
solid orange and activating the unit will result in an error sound.
See section VII. Troubleshooting.
VI. CLINICAL APPLICATION
CAUTION: Always test restorative materials with this LED light
by using the supplied test block.
• Polymerization: Determine the exposure time in accordance
with the dental material manufacturer's instructions using the
test block provided.
• Remove the charged handpiece from the charger base;
position the light shield; slide the barrier sleeve over the light;
attach the light shield; direct the tip of the light lens as close
to the restorative material as possible without touching.
®
• Activate Coltolux LED with a momentary push of the button.
Avoid contact with unpolymerized restorative material,
glass ionomer, liquid resin or bonding agent because direct
contact will cause these materials to adhere to the light lens.
This will block the light transmission and result in improper
polymerization.
VII. TROUBLESHOOTING
A. If the light on the charger base does not illuminate:
• Check to see that the power cord is securely plugged into
the charger base and the wall outlet.
• Ensure the wall outlet has power by plugging a lamp into it.
B. If the On/Off button on the handpiece does not activate the blue
LED curing light and the green light on the handpiece is not lit
(and handpiece is not in base):
• The unit may be discharged and needs charging.
Replace handpiece in the charger base. If the charger base LED
is red, handpiece is being charged. If the charger base LED is
green and the handpiece indicator light remains unlit, the unit
requires service. Contact your dealer or Coltène/Whaledent Inc.
C. If the On/Off button on the handpiece does not activate
the curing light and the green light above the button is
illuminated, unit requires service. Contact your dealer
or Coltène/Whaledent Inc.
D. If your light registers a reading below 300 mW/cm
a light meter, take the following steps:
• Check the light lens. The light lens should be checked daily.
Replace lens with Coltène/Whaledent Inc. Light Lens
(Cat. No. C7972) if material has cured to the lens or if it
is otherwise obstructed.
• If the intensity of the light output is still under 300 mW/cm
extend the curing time according to the material's manufacturer
recommendation until the Coltolux
Contact your dealer or Coltène/Whaledent Inc. for service.
E. If activating the unit results in an error sound and
the indicator is solid orange:
• The unit requires service. Contact your dealer
or Coltène/Whaledent Inc.
VIII. REPLACING THE LIGHT LENS
IMPORTANT: The Coltolux

and must be handled with care at all times.
CAUTION: Only use Coltène/Whaledent's Light Lens
(Cat. No. C7972). Do not use other manufacturer's light lens
with this product.
