Speed (Hertz) : Frequence of the light flashes.
Start by the speed: Press “Modify”: Increase or decrease gradually until the reader no longer perceives the light flashes and feels comfortable reading.
Balance (%) : The LEDs are switched off in % of the lighting time.
Then, go to balance: Repeat the same procedure as with speed.
Continuous lighting: Interrupts the pulsed effect, the light becomes continuous. The speed and balance settings are removed.
Finally, without telling the reader, activate the continuous mode and ask him/her about his/her feelings. Do the same after switching off the continuous mode. If the patient identifies a benefit when returning to pulsed light, Lili is effective for them.
