TRAIL OPTIONS
The line extending from the present position symbol is
called a plot trail. You can customize the plot trail and
save trails using the trail options menu. To use it, press
the MENU key, select “MAP SETUP”, then “TRAIL
OPTIONS”. The screen at right appears.
Clear Trail
To erase the current plot trail from the screen, select
Clear Trail from the Trail Options menu. A message ap-
pears, asking if you really want to erase the plot trail.
Follow the instructions on the screen. When the trail is erased, the unit
returns to the map screen.
Flash Trail
By default, the plot trail flashes once per second. This typically makes it
easier to see the plot trail against the background map. To turn the flash-
ing off, select “FLASH TRL” from the trail options menu. Press the left
arrow key to turn it off.
Update Options
By default, the plotter places a dot on the screen every
3 seconds to create the plot trail. You can change this
time from once per second to once every thirty min-
utes. The plot trail can also be updated by distance
instead of by time. The distance update rate can be set
from 0.01 to once every 10 miles.
From the trail options menu, choose “UPDATE BY” to
change the update rate or type. To change the rate or
distance, simply select either the “UPDATE RATE” or
‘UPDATE DIS” menus as appropriate, use the left or right arrow keys to
adjust it, then press the EXIT key to erase the menu.
PLOT TRAILS - Save Trail
This unit automatically saves the current plot trail in
memory when you turn it off. You can save two other
trails in memory. To save your current plot trail in a spe-
cific memory location, choose “SAVE TRAIL” from the
“TRAIL OPTIONS” menu. The screen shown at right
appears. Highlight the desired number that you wish to
save the current trail under, (i.e. “Trail 1 or Trail 2) and
press the right arrow key. Your current trail is saved.
Press the EXIT key to erase this menu.
