WARNING: For safety reasons, GNC 255 operational procedures must be learned on the ground. CAUTION: The Garmin GNC 255 does not contain any user-serviceable parts. Repairs should only be made by an authorized Garmin service center. Unauthorized repairs or modifications could void both the warranty and the pilot's authority to operate this device under FAA/FCC regulations. CAUTION: The GNC 255 display uses a lens coated with a special antireflective coating that is very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE ANTIREFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free cloth and an eyeglass lens cleaner that is specified as safe for anti-reflective coatings. NOTE: Garmin recommends that if flying in a region with 8.33 kHz COM channel spacing, the radio should remain in 8.33 kHz mode. This will prevent the loss of stored user and recent frequencies. NOTE: Do not use outdated database information. Databases used in the system must be updated regularly in order to ensure that the information remains current. Pilots using an outdated database do so entirely at their own risk. NOTE: All visual depictions contained within this document, including screen images of the GNC 255 bezel and displays, are subject to change and may not reflect the most current GNC 255 software.
