"I need to have the black light on longer than the 20 seconds when it starts to dim?"
-You could push one of the up/down or menu buttons again, which should reset the light's timer for another 20 sec., or whatever the (factory set) duration is
AFAIK, the duration is not user adjustable... at least on the G2/3 SK100 Body pack transmitter and EK100 portable receiver.

But I have the G3 wireless and how do you keep the backlight on?

I need to have the black light on longer than the 20 seconds when it starts to dim?




My question would be - why?

The backlight going off is to: A) to prevent an annoying glow from the equipment during a performance and B) to maximise battery life.

The 20 odd seconds is normally more than enough to make adjustments and is from the last button press.
