Fixed time trails
When the elapsed time clock counts up to
the trail time selected, the elapsed time
display freezes. The oldest portions of trails
are erased so only the latest trail, equal in
length to the trail time selected, is shown.
Then, trails start extending again. For
example, the one minute trail time is
selected. When the elapsed time display
freezes at 60 seconds, all but the latest one
minute of trails are erased and then trailing
continues.
Continuous trail
The maximum continuous trail time is 99
minutes and 59 seconds. When the
elapsed time clock counts up to that time
the elapsed time display is reset to zero, all
trails are erased and then trailing is
restarted.
