some batteries. Some batteries can rupture at high temperatures.
Performance
Receiver: WAAS enabled
Acquisition Times*:
Approx. 1 second (warm start)
Approx. 38 seconds (cold start)
Approx. 45 seconds (factory reset)
*On average for a stationary receiver with an open sky view.

*Alkaline batteries lose a significant amount of their capacity as the
temperature decreases. Use Lithium batteries when operating the GPSMAP
76Cx in below-freezing conditions. Extensive use of screen backlighting, and
audible tones significantly reduce battery life.

imposed Selective Availability (SA) Program when activated.
DGPS: 3-5 meters (10-16 feet) 95% typical*
*
WAAS accuracy in North America.
