The indicator above the light meter lights up green
according to the light output measured. Each lamp
indicates a light output of approximately 200 mW/cm
(see Indicators on the handpiece holder). If the value
measured does not correspond with the expected light
output, proceed as follows:
– Check the selected curing program
– Clean the light meter with a moist cloth
– Clean any light probes which may be dirty
(see Maintenance and cleaning)
– Replace any damaged light probe with a new one
If these measures do not improve the readings, please
contact your dealer or local Service Center.
The light meter is not suitable for measuring the light
output of other light-emitting devices or light probes.

Maintenance and cleaning
Make sure that no liquids and other foreign substances
enter the handpiece, handpiece holder and particularly
2
the power pack (electrical shock hazard).
Disconnect the handpiece from the power source when
cleaning it.
Housing
Wipe the handpiece and handpiece holder with a
standard aldehyde-free disinfecting solution. Do not
clean with highly aggressive disinfecting solutions
(e.g. solutions containing orange oil or solutions with
an ethanol content of more than 50 %), solvents (e.g.
acetone) or pointed instruments, which may damage or
scratch the plastic. Clean dirty plastic parts with a soap
solution.
Light probe
Clean light probes with a disinfectant and a soft cloth.
Carefully remove any possible material residue, such as
composite material, from the light probe with e.g. finger-
nails or a plastic spatula. Do not use sharp or pointed
instruments, since they may scratch the surface of the
light probe and thus reduce light transmission. Light
probes and anti-glare cones may be autoclaved
(e.g. 134 °C, 3 bar, 5 minutes).
Check light probes for damage. If the light probe is held
against a light source and certain segments appear
black, then the glass fibres are broken. In this case, the
light probe has to be replaced with a new one.
