Instructions for use KEY Laser III 1243
4 Operation

4.9 Modes

4.9.4 Feedback mode

The feedback mode combines the detection function of the detection mode with the

therapeutic function of the laser beam.

When the laser pulse trigger is pressed in the ready mode, laser pulses are triggered

only when, as a result of the detection, an altered tooth substance is found, i.e. when

the fluorescence measurement is above the said threshold value.

As soon as the fluorescence measurement falls below the threshold value, triggering

of laser pulses is stopped.
