Second press to the RL/TL button to turnoff/on the illumination (the indicator light not affected).Intensity/LM knob(see Fig. 2-6/10)Yes Yes YesTurn: Controls the light intensity of the active light sourceShort press *:Repeated short pressing switches a single LED or allLEDs of the Colibri 3 together on or off (if Colibri 3 isconnected).Long press **:Saves the set light intensity. During this action, theindicator light blinks twice in GREEN and the imagebackground appears BLACK for 300 ms (this does notapply to halogen illumination).Long press for20 s:Activates the factory default settings (enables LightManager, sets light intensity to the initial value, clearsall saved parfocal positions).When the knob is pressed, the indicator light startsblinking in RED after 3 s until 20 s is reached. After20 s, the indicator light blinks in GREEN. Then releasethe knob. The indicator light turns to GREENpermanently if the system reset is done.After factory default reset, need re-power on thesystem.* Short press: hold less than 1 second, then release.** Long press: hold at least 1.5 seconds.*** BLINK: the indicator light alternately goes on/off at 500 ms intervals.
