4. Setting a trail reference level (trail threshold) [TRAILS]
A trail reference level is used to determine whether to store trail data depending on the
strength of targets.
A level 0 to 15 can be set as a threshold.
When level 1 is set, the data of all the targets displayed on the PPI screen is stored/displayed.
As a higher level is set, the trail data of only stronger targets is stored/displayed.
Level 8 is usually set.
If sea clutters are strong and they are also stored/displayed, set a level higher than 8.
Conversely, if the trail data of weak targets is difficult to store/display, set a level lower than 8.
