Subject to accuracy degradation to 100m 2DRMS under the U.S. DoD-imposedSelective Availability Program.2. With optional GARMIN GBR 21 Beacon Receiver input.3. The temperature rating for the eMap may exceed the usable range of somebatteries. Alkaline batteries can rupture at high temperatures. Alkaline batterieslose a significant amount of their capacity as temperature decreases. If using theeMap in below freezing temperatures, use lithium batteries for longer battery life.4. Extensive use of backlighting will also significantly reduce battery life.5. External power can only be applied using the GARMIN Vehicular Power Adapter or PCInterface Cable with Vehicular Power Adapter with self-contained voltage regulation-
