Warnings, Cautions & Notes
CAUTION
Do not clean display surfaces with abrasive cloths or cleaners containing ammonia.
They will harm the anti-reflective coating. Use a clean, lint-free cloth and anti-reflective
lens cleaner.
CAUTION
Ensure that any unit repairs are made by an authorized Garmin service center.
Unauthorized repairs or modifications could void both the warranty and affect the
airworthiness of the aircraft.
NOTE
Foreign materials (i.e., moisture, objects) that come into contact with the touchscreen
can prevent the unit from responding to touch commands. To restore functionality, wipe
the screen dry and/or remove interfering objects.
NOTE
The COM 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
Mounted along the fuselage, the COM transceiver antenna(s) of the equipment is (are)
accessible only to aircraft maintenance personnel.
NOTE
All visual depictions contained within this document, including screen images of the
system panel and displays, are subject to change and may not reflect the most current
system software and aviation databases. Depictions of equipment may differ slightly from
the actual equipment. Feature depictions may differ from actual unit features depending
on configuration.
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.
