3.7 Display ship’s trail
Displaying the target ship’s trail is done as follows.
Two types of display mode, relative display (REL) and true display (TRUE) are available.
At the start of test, “TRAIL” characters at lower left of the screen change to yellow.
* The trail by its nature records and displays past images. The trail does not display an image just after
being transmitted.
In addition, after the change of [TIME], or after the change of two or more steps of [RANGE], the trail
does not display an image, because the record is reset (erased).
* The trail can be changed directly at the lower left of the screen, with trackball and [ENT] key, without
using menu function.

* [TRUE/REL] is in common with [PAST POSN]. So, if you change one part, the other part will
change accordingly.

[DETECT LEVEL]: This is to set up echo level of trail to be recorded.
