Curing Mode (continued)

To change from the C1 to the C2 timer, press the LEFT and RIGHT arrow keys

on the CONTROL WHEEL. The display windows show “C2” in the MODE

window and “05” in the SETTING window.

The ACTIVATOR button on the curing handpiece will activate and deactivate

the lamp. The TIMER SELECT button on the curing handpiece will alternate

between the C1 and C2 timers.

ATTENTION: DO NOT HOLD DOWN THE START/STOP OR ACTIVATOR

BUTTON. PRESS AND RELEASE.

Fast Start

When the curing handpiece is installed, pressing the ACTIVATOR button on the handpiece or START/STOP

button on the front panel will immediately activate the lamp and start the countdown timer. The timer setting will

be either the factory-default 5 seconds or the last setting, from 1 to 10 seconds, when the power was turned off.

When the CURE mode is selected, it is necessary to power down or unplug the light guide to reset the system

and change to BLEACH mode.

Recommended Use of Both Timers

When placing LUMINEERS

, set timer C1 for 2 seconds and timer C2 for 5 seconds. use C1 for spot curing

LUMINEERS with the 2 mm tacking tip, and use C2 for ﬁnal curing with the 9 mm tip. use the TIMER SELECT

button to quickly alternate between the C1 and C2 timers. Spot curing with the 2 mm tacking tip makes clean-up

of margins a breeze and greatly reduces ﬁnishing time.

Curing Instructions

NOTE: Clean the tip prior to use for maximum light output.

ATTENTION: Do not touch the curved tip of the light guide handle to the restorative material. Hold the tip

approximately 2 mm above the material to be cured!

It is recommended that you test all restorative materials for the time required for complete curing prior to use. The

curing test rings provided with the Sapphire are 2 mm deep x 5 mm interior diameter. Fill the ring with the restorative

to be used. Set timer C1 or C2 to 5 seconds. Position the curved tip of the handpiece approximately 2 mm from the

composite and start the system. After the timing cycle is completed and the light turns off, test the bottom surface for

hardness using a dental probe. If the material is not completely cured, restart the system again for another 5-second

exposure. Test, and repeat again, if necessary. This will give you an indication of the optimum timing increment for

the speciﬁc restorative to be used. Select a new timer increment which is close to the total time it took to cure the

material. Repeat the test and verify that complete curing has occurred. If curing time is longer than 5 seconds, it is

recommended that you repeat an additional 5-second exposure. It is important that you maintain a log of composite

materials, shades, and associated curing times. This log can also be used to monitor system performance.

If the cavity preparation is deep, an incremental ﬁlling technique is recommended and each increment should be

cured following the manufacturer’s guidelines or your own experience with the restorative being used.

CAUTION: Do not direct the light on to unprotected gingiva or skin.
