(highlight Select All for complete deletion), press ENTER, then Apply, then OK to confirm your
selection.
To turn off the GPS unit, press in and hold the power button until it turns off (if you quickly press the
power button the backlight adjustment control will appear -useful if working in low light levels).
The Garmin 76CS is a Wide Area Augmentation System (WAAS) capable receiver. It offers potential
accuracy of 1-2 meters horizontal and 2-3 meters vertical, provided ground based reference stations
are nearby. Enabling WAAS in regions that are not supported by ground stations, which corrects
position data, typically does not improve accuracy even when receiving signals from satellites. In fact
it can degrade the accuracy to less than that provided by GPS satellites alone. For this reason, the
Garmin GPS receiver, when in the “WAAS Enabled” mode, automatically uses the method that
achieves the best accuracy.
Unit Accuracy
You can also average a new waypoint over time to produce a more accurate location. For more
information, please consult the complete owner's manual.
