Knob Function

Brightness knob: Color temperature knob: Rotate knob to adjust 1-100% brightness Rotate knob to adjust temperature value,
When turn off light, display OFF. From White to cold white (2700-6500K), display 270-650.
Brightness 100% Warmwhite, 2700K
Note: When display OLA, overload alarm. When display OHA, overheat alarm.
PWM Frequency Setting
1. Push twice Match key fastly, enter PWM frequency setting state, then rotary color temperature knob to select seven PWM frequency: 250Hz(F02), 500Hz(F05), 1KHz(F10), 2KHz(F20), 4KHz(F40), 8KHz(F80) or 16KHz(F16).
2. Rotary brightness knob or timeout 10 seconds, automatically exit PWM frequency setting state.
3. Higher PWM frequency, will cause lower output current, higher power noise, but more suitable for camera(No flickers for video).
4. Default PWM frequency: 2KHz.
Color temperature output mode
Two color temperature output mode selectable: NW=50%WW+50%CW or NW=100%WW+100%CW.
Long press match key for 10s, restore factory settings, set NW=50%WW+50%CW, display RES.
Long press match key for 15s, set NW=100%WW+100%CW, display C10.
