● Do not use this function to view the radar beacon, the START signal, or a target
moving at a high speed on the radar screen.

● This function is used most suitably in TM mode.
When you use the function in RM mode, select N-UP or C-UP. Use of the
function with H-UP may cause images to be blurred.
1. Setting image processing [MENU]
There are three types of image processing, PROC1, PROC2, and PROC3.
PROC1: Select PROC1 when there is a target moving at a low speed.
The image of a relatively unstable target is highlighted and displayed in stable
state.
PROC1 is effective for suppressing irregular signals like sea clutters.
However, the image of a target moving at a high speed dims.
Use PROC1 in a range of 1.5 nautical miles or less as a rule of thumb.
PROC2: Select PROC2 to display images in more stable state than "PROC1" does.
PROC2 is effective particularly when there are many sea clutters.
Use PROC2 in a range of 3 nautical miles or more as a rule of thumb.
PROC3: Select PROC3 when a target is not displayed at the very limit of remote noise.
Use PROC3 in a range of 6 nautical miles or more as a rule of thumb.
Disadvantage of PROC3 is that the target may be more difficult to observe because
noise or the like also appears clearly.
PROC1+3: PROC1 is performed in a preset processing range (the processing range from own
ship), and PROC3 is performed outside the processing range (the processing range
or more).
Use PROC1+3 as navigation when you want to display a target at the very limit of
remote noise while performing PROC1 that makes it easy to observe other ships
influenced by sea clutters in short range.
PROC2+3: PROC2 is performed in a preset processing range (the processing range from own
ship), and PROC3 is performed outside the processing range (the processing range
or more).
Use PROC2+3 as navigation when you want to display a target at the very limit of
remote noise while performing PROC2 that makes it easier to observe other ships
influenced by sea clutters in short range than PROC1 does.
