Welcome
The GPSMAP 276C uses GPS technology in order to fi nd your
precise location. GPS stands for Global Positioning System,
a group of 24 satellites, circling the earth twice a day at an
altitude of about 12,000 miles. The satellites transmit very low
power radio signals containing position and time information,
allowing anyone with a GPS receiver to determine their location
on the Earth within 100 meters or better. For more detailed
information regarding GPS, Garmin has prepared a booklet
titled “GPS Guide for Beginners” available from our Web site at
www.garmin.com.
