Lowrance electronic LMS-480DF, LMS-480M Press MENUMENU↓ to GPS SETUPENT↓ to Require Dgpsent

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.)

1.Press MENUMENU↓ to GPS SETUPENT↓ to POSITION PINNINGENT.

Require DGPS

You can force the unit 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 manda- tory DGPS on and off.

1.Press MENUMENU↓ to GPS SETUPENT↓ to REQUIRE DGPSENT.

3.You can return to this command and press ENT again to turn the fea- ture off.
