12. LIGHT CONTROL FREQUENCY
1 2
ENTER
The Frq function allows for setting the basic control frequency for the LEDs. This function is
extremely useful in applications for the television industry. By applying the "flicker free"
technology, it is possible to avoid the unpleasant flickering effect which is caused by improper
signal synchronization that controls the LEDs. The user can choose from the available frequency
range from 366 Hz up to 25.0 kHz which can be smoothly changed using the previous or next
buttons and selecting a different value.
The frequency value in the upper range (e.g. 1.50 = 1.5 kHz) helps to avoid the flickering effects
that are visible in video cameras.
To set the selected range of basic frequencies:
1. Set the Frq function.
2. Set the selected value using the „next” or „previous” buttons.
