color bars and/or audio test tones are transmitted after a
specified delay.
• A Stby (Auto Standby) - If a loss of video signal occurs,
the transmitter is automatically placed into standby (PA is

your IDU and you select the Color Bars screen On, A
Gen, or A Stby option, selection of an analog Preset will
result in no audio, video, or color bar outputs.
