3.6 Video mode (VIDEO)
This is a function to change the relation between the strength of signal of target echo and their display
gradation.
At [VIDEO 0], the difference of signals strength between dark images and bright images becomes
larger. As the numerical figure becomes larger as [VIDEO 1], [VIDEO 2] and [VIDEO 3], the difference
in signal strength becomes smaller.
At [VIDEO 4], the difference of signal strength becomes gradually smaller in the range at close to 5 NM
and becomes constant at 5 NM or higher. When the difference of signal strength is large, it will be easy
to display clutter at darker level and targets at brighter level.
[VIDEO] can be changed directly at the upper light of the screen.

Move the cursor to the setup value window of [VIDEO] at the upper right part of the screen.
Press [ENT] key repeatedly until desired value appears.
When the difference of signal strength is small, images becomes sharper.
However, signal strength from small ships and buoys is weak, and the difference between clutter and
them is not large enough.
Therefore, it is necessary to display the clutter not to get in the way and not to overlook small ships and
course buoys. Therefore, it is recommended to use [VIDEO 1] or [VIDEO 4].
