by watching the display.
Note:
• In typical environment RAIN should be turned all the way down via RAIN knob, and no white level
should be indicated by RAIN window.
• Turning the knob to the right shows profiles of the targets hidden in the rain/snow image, but care shall
be taken that small target may be hidden and not displayed.
• Small target becomes harder to detect when RAIN is used together with SEA.
