Thank you for purchasing the Radii Plus LED curing light. The Radii Plus is a
powerful, cordless, lightweight curing light using an LED for the polymerization of
composite restorative materials that contain the photo-initiator Camphorquinone.
The Radii Plus produces a strong blue light in the wavelength range of 440 – 480
nm, the relevant range for Camphorquinone containing products. The Radii Plus
features a ‘NO RAMP’ mode and ‘RAMP’ mode for convenient polymerization
shrinkage minimization of composite materials. In addition to this, the
LED attachments can be changed depending on the clinical application.

• 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.
Below is a table explaining the audible beeps for each mode.

At the end of 60 seconds (or 65 seconds in case of “RAMP” mode) one long beep
will be heard before the blue LED is automatically switched off.
NOTE: The above cycle is based on the Standard LED attachment supplied in this
kit. Other access types of LED attachments from SDI will have different cycles. Refer
to instruction sheets associated with those products for beeping cycle.
• 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:
• Lens Cap
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.
Note:
Portable radiometers can give inaccurate and inconsistent results. These
results can vary by as much as 300 mW/cm
2
or more.
• 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.

INSTRUCTIONS FOR USE
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 by
placing fingers as shown below. Please refer to LED attachment instructions for use
for operation guidelines.
• 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.

cautIoN!
Irradiation of the eyes bears an inherent health risk. Hence,
the light must not be directed towards the eyes. Exposure must be
restricted to the area of the oral cavity in which clinical treatment is
intended. Suitable blue-light filtering safety goggles should be used.
The Radii Plus emits a high intensity light and intensive light exposure of
soft tissues (gingiva, oral mucosa and skin) should be avoided as this
exposure may cause damage or irritation.The emitted light should be
placed directly above the material to be cured. If applicable cover soft
tissue areas.
Do not use the Radii Plus in patients or by users with:
• heart pacemaker implants who have been advised to be
cautious in regards to their exposure to small electrical devices.
• a history of photo biological reactions (including individuals
with urticaria solaris or erythropoietic protoporphyria) or who are
currently on photo-sensitizing medication (including 8-methoxypsoralen
or dimethylchlorotetracycline).
• a history of cataract surgery. These people may be particularly
sensitive to the exposure to light and should be discouraged from Radii
Plus treatment unless adequate safety measures, such as the use of
protective goggles to remove blue light, are undertaken.
• a history of retinal disease. These people should seek advice from
their ophthalmologist prior to operating the unit. In operating the Radii
Plus unit, this group of individuals must take extreme care and comply
with all safety precautions (including the use of suitable light-filtering
safety goggles).
