Specifi cations subject to change without notice.
1. Subject to proper user calibration.
2. The temperature rating of the GPSmap 76CS may exceed the usable range of some
batteries. Some batteries can rupture at high temperatures.
3. Subject to accuracy degradation to 100m 2DRMS under the U.S. DoD imposed Selective
Availability (SA) Program when activated.
4. WAAS accuracy in North America. (DGPS using Beacon Receiver input.)
5. Alkaline batteries lose a signifi cant amount of their capacity as the temperature decreases.
Use Lithium batteries when operating the GPS map 76CS in below-freezing conditions.
Extensive use of screen backlighting, electronic compass and audible tones signifi cantly
reduce battery life.
