sources when they occur. During flight operations, compare display indications
to information from other NAVAIDs, visual sightings, charts, and other available
sources before continuing navigation.

NOTE
The application supports channel tuning for both 8.33 kHz and 25 kHz channels within
radio-frequency range. If flying in a region where 8.33 kHz channel spacing is available,
set the COM radio to 8.33 kHz to prevent the loss of any stored or recently used
frequencies.

NOTE
The United States government operates the Global Positioning System and is solely
responsible for its accuracy and maintenance. The GPS system is subject to changes
which could affect the accuracy and performance of all GPS equipment. Portions of the
system utilize GPS as a precision electronic NAVAID. Therefore, as with all NAVAIDs,
information presented by the system can be misused or misinterpreted and, therefore,
become unsafe.
