Switch mode

The mode is activated (DETECT or FEEDBACK) with a shining key with dark let‐

tering.

To switch to the other mode, press the corresponding key.

After pressing the key, the just activated mode is bright with dark text.

Note
Detection and feedback mode are mutually locked against each other. When de‐

tection mode is activated, it deactivates feedback mode and vice versa.

4.9.2

Standard therapy mode

Press the bright mode key to deactivate the selected mode without activating the

other modes. This shuts off both detection and feedback mode. No information ap‐

pears in the area between the frequency readout and mode key.

Note
The laser can be operated under this setting but without the feedback function.
