The GPS system is operated by the government of the United States, which is solely responsible for its accuracy and
maintenance. Although the GPS 18x is a precision electronic NAVigation AID (NAVAID), any NAVAID can be
misused or misinterpreted, and therefore become unsafe. Use these products at your own risk. To reduce the risk,
carefully review and understand all aspects of these Technical Specifications before using the GPS 18x. When in
actual use, carefully compare indications from the GPS to all available navigation sources including the information
from other NAVAIDs, visual sightings, charts, etc. For safety, always resolve any discrepancies before continuing
navigation.
