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.
WATER FILLED
WITH GRAY
LAND FILLED WITH
GRAY
Gray Fill
When this unit is first turned on, all water (lakes, oceans, rivers) is filled
with gray to distinguish it from land, which is clear. (See below) To make
the land fill with gray and water remain clear, select the “Gray Fill” label
from the Earth Map menu, then press the left arrow key. Press the EXIT
key repeatedly to return to the mapping screen.
Normally, you'll want to fill water with gray when you're using the GPS
receiver on land and fill land with gray when you're using it on the water.
