I cannot use the CRC button?

Why can I not use the bottom corner signals?

What is its weight

What is its dimensions

Power down the instrument, hold the 100% bar button down and now power on, the text willl now be scrolling. This feature disables the selection of any other button i.e. you cannot change signal, to do so would mean turning the scrolling text off (power down then power on) select new signal then switch scrolling text on

The CRC function is only available if all 'shift' functions are turned off i.e. ID and MPEG pattern

When the text ID is turned on i.e. the black line near the top of the screen with characters on the bottom corner buttons are used to move the text along the line. To use these signals first turn the text ID off, select signal, then turn text ID on
