5 Maintenance
5.1 Light output monitoring
1. Make sure that the LED aperture is clean and scratch-free; otherwise light output will
be reduced and may be insufcient for proper curing of the material.
2. The light intensity of SmartLite®Focus®should be checked frequently to ensure ap-
propriate curing by using a commercially available radiometer. As radiometers differ
greatly, the following procedure is recommended.
3. Upon receipt of SmartLite®Focus®check the light intensity with the radiometer of
your choice and record the value. This initial reading is for reference only, and may
not represent the actual light intensity.
4. For subsequent monitoring retest the light intensity with the same radiometer that
was used for the initial reference and compare it to the reference intensity.
5. If radiometer value drops below reference intensity, light efciency can be veried
using the i.Cure. Place i.Cure on a sheet of paper on a at surface. Choose i.Cure
segment according to step height required (please note that the step height should
be twice the curing depth to be conrmed). Fill with composite. Hold SmartLite®
Focus®in close proximity to the upper aperture and cure. If the material on the lower
aperture has been cured (i.e. cannot be scraped off with a plastic spatula), the curing
depth according to ISO 4049:2009 equals half the chosen step height. If i.Cure test
is successful, SmartLite®Focus®is ready to use.
6. Do not continue to use SmartLite®Focus®if both light output is below reference inten-
sity and i.Cure test has failed.
5.2 Battery 2
• Battery is equipped with low self discharge technology resulting in a long operating
life.
• Battery is pre-charged and ready to use upon purchase. Charging before rst use
may improve initial operating time but is not mandatory.
• When the battery light ashes green 1.2 , the battery is charging. Upon com-
plete recharging, the battery light remains permanently green. The battery needs
approximately 3 hours to be fully recharged. SmartLite®Focus®has a Smart Re-
charging Technology. Depending on battery status, SmartLite®Focus®will automati-
cally choose between Automatic Quick Charging Mode (fast ashing green light) and
Standard Charging Mode (ashing green light).
• The SmartLite®Focus®Automatic Quick Charging Mode allows a minimum of 5 min-
utes operating time after 10 minutes recharging.
• When the battery light ashes yellow (fast) 1.3 , the battery needs to be recharged.
At rst occurrence approximately 1 minute curing time remain for completion of the
treatment. Light output is not reduced during this period. After this period, the device
switches off automatically and the battery light remains permanently yellow indicat-
ing the need to recharge.
• If the battery pack 2needs to be replaced, release battery pack by gently inserting
a screwdriver into the hole at the lower back end of the handpiece. The screwdriver
is just needed to unlock the battery pack, please use ngers to completely remove
battery pack as shown in Figure A4 and Figure A5 .Do not use the screwdriver as
a lever, in order to avoid damage to the SmartLite®Focus® handpiece.
