UNPACKING AND INITIAL CHARGING
The Radii Plus has been carefully packed to withstand any damage during transit.
Ensure all parts contained within the box match the product contents list above.
1) Remove all parts from the box.
2) Place the plug pack cable into the charger.
3) Fix the correct adapter head onto the plug pack.
4) Plug the plug pack into an available power outlet and turn power outlet on.
The charger will conduct a brief LED test: the charge light LED should momentarily
show red/green and the 5 blue radiometer LEDs should turn on/off.
5) Place the curing light handpiece into the charger. The handpiece can be rotated
360º in the charger. Depending on the length of time from manufacture to
package opening, the charge remaining in the battery can vary. The charge light
will show the below three conditions.
Charge Light Color Battery condition
Red – discharged
Flashing Green charging - OK to use
Green – charged
To ensure the highest level of performance, allow the Radii Plus to fully charge
prior to first use. On average, it will take approximately 1-3 hours to initially charge
the Radii Plus
• Turning unit on and off
Simply pick up the curing light handpiece, press the on/off button once to activate
and de-activate the light. Audible beeps facilitate accurate time measurement of
curing. Replace the Radii Plus back in the charger when not in use.
• NO RAMP mode and RAMP mode.
The Radii Plus has two curing modes, NO RAMP and RAMP mode. NO RAMP mode
will output 100% intensity immediately after pressing the on/off button whereas
RAMP mode will output a reduced intensity for the first 5 seconds before
irradiating at 100% intensity.
• Switching between the NO RAMP mode and RAMP mode.
The Radii Plus has been set at the factory to the NO RAMP mode. To switch
between the NO RAMP mode and RAMP mode, when the Radii Plus is off, hold
down the on/off button for 3 seconds. Two audible beeps will be heard. The unit
will now be programmed for RAMP mode. To switch back to the NO RAMP mode,
hold down the on/off button for 3 seconds, a single audible beep will be heard
indicating the unit has switched back to NO RAMP mode.
NOTE: In RAMP mode
the visible light starts slightly dimmer and progressively gets stronger, as opposed
to in NO RAMP mode, where the visible light is constant from the start
RAMP mode indicator:
This unit has been fitted with a blue indicator light above the on/off button.
When in RAMP mode, the indicator light will show blue. The indicator light is
off in the NO RAMP mode.
• Audible beeps for NO RAMP and RAMP modes:
Depending on the mode set (NO RAMP or RAMP), the beeping cycle will differ.
Rotating and changing the LED attachment
The LED attachment, can be rotated 360º to ensure accurate and detailed
polimerization in any area of the mouth.
WARNING: Do not rotate the LED attachment at the LED end, instead turn at the
end closer to the control section as shown below:
The Radii Plus has been supplied with a lens cap fitted. The lens cap should be
inspected prior to each use for scratches, cracks or foreign matter that may reduce
the effectiveness of the LED light source. Generally lens caps should be replaced
every 2 weeks. To remove the lens cap carefully unscrew the old lens cap counter-
clockwise and fit the new lens cap by tightening clockwise.
• Built in Radiometer
The Radii Plus’s built-in radiometer provides a simple test to check the
functionality of the unit. With the Radii Plus on, carefully position the lens
cap on the built-in radiometer. 4 or 5 lights should illuminate indicating a
fully functional unit. If only 1,2 or 3 lights illuminate, it could be due
to the following reasons:
1) There could be some material on the lens cap such as composite: - the
lens cap should be replaced.
2) The lens cap could be damaged or cracked: - it should be replaced.
3) The battery could be extremely low - the unit should be recharged.
4) In a severe case the light could be malfunctioning: - the unit should be serviced.
• Disposable barrier sleeves
Transparent, disposable barrier sleeves are supplied to protect the handpiece and
prevent cross contamination. Testing showed no significant difference in spectral
and energy output when operating with or without a barrier sleeve in place.
Slide the barrier sleeve over the end of the handpiece before placing the orange
light shield on the end of the handpiece.
It is essential to use disposable barrier sleeves to prevent any liquids
getting on the handpiece. Evidence of liquids entering handpiece causing
damage due to not using barrier sleeves will void warranty
• Automatic shut off function using the standard LED attachment
Should the Radii Plus standard LED attachment become too hot due to
excessive use (after about 4 minutes of continuous irradiation), the unit will
automatically shut off and be un-usable for about 1 minute until it cools down.
If using a different LED attachment, please refer to the instruction sheet for that
attachment’s automatic shut-off sequence as it may vary.
• Changing the LED Attachment
The Radii Plus allows you to change the LED attachment depending on the curing
situation. To change the LED attachment, pull off the LED attachment carefully.
• Changing the battery pack
Carefully unscrew the battery pack counter-clockwise to remove and replace. A
single beep will be heard when the battery pack is successfully connected.
• Cleaning the Radii Plus:
The ideal way to protect patients from cross-infection is to utilise Radii Plus barrier
sleeves. Barrier sleeves are also essential to keep the Radii Plus clean. When
cleaning the Radii Plus handpiece, ensure lens cap, battery pack, control section
and LED attachment are connected as one unit.
LIQUID CONTACT WITH TERMINALS OF
HANDPIECE AND CHARGER WILL CAUSE
DAMAGE VOIDING WARRANTY.
• LIQUID CONTACT WITH LED WILL CAUSE
DAMAGE VOIDING WARRANTY.
• LIQUIDS MUST NOT ENTER ANY PART OF THE
HANDPIECE OR CHARGER.
• DO NOT SPRAY LIQUIDS DIRECTLY ONTO, OR
APPLY COPIOUS AMOUNTS OF LIQUIDS TO
THE RADII PLUS.
• DO NOT AUTOCLAVE THE RADII PLUS.
• General Surface Cleaning
General surface cleaning can be conducted with anti-microbial
surface disinfectant such as Glutaraldehyde, Chlorhexidine
gluconate, and 70% Isopropyl alcohol. When applying the
disinfectant to any component of the device, spray the disinfectant
agent onto a piece of cloth and wipe over the external areas to be
• Curing Times
Curing times will differ for different formulations of composite restorative
materials. Follow the manufacturers instructions for recommended curing times.
Always bench test new materials before use in-vivo.
• Disposal of battery pack
As a means of protecting the environment, the Radii Plus battery pack is fitted with
a Lithium Ion battery pack. Dispose of battery pack in accordance with local legal
