The command remains available in the unit's software, but we recom-
mend that you leave it in the default off (unchecked) mode. The "wan-
dering" plot trail issue has now been corrected by the Track Smoothing
feature. Turning on Position Pinning could actually result in an inaccu-
rate plot trail if you are moving around in a relatively small area. If you
want to experiment with Position Pinning, the same instructions are
used to turn the feature on (checked) and off (unchecked.)

Require DGPS
(SeaCharter 480DF only)
You can force the SeaCharter 480DF to require DGPS for reporting a
valid position. (The default setting, off, uses DGPS automatically when
an optional DGPS beacon receiver is connected. However, this auto
mode doesn't require DGPS reception to yield a position.) Here's how to
turn mandatory DGPS on and off.
1. Press
MENU|MENU|↓ to GPS SETUP|ENT|↓ to REQUIRE DGPS|ENT.
2. To return to the last page displayed, press
EXIT|EXIT.
3. You can return to this command and press
ENT again to turn the fea-
ture off.
