This function allows you to monitor the video depth of modulation in

graphical and precise numerical format. A marker is placed at the

optimal modulation level (NTSC 87.5%, PAL 90%) to assist techni-

cians while making adjustments.

An Audio and Depth soft key is used to select the type of modulation

to be displayed.

An additional feature is the ability to listen to the audio modulation

of the tuned channel or frequency. Use the Audio soft key to listen to

the audio modulation.

Use the UP and DOWN arrow soft keys to adjust the volume.
