: Do not operate the radar in a hangar unless the energy is directed toward an absorption shield to prevent reflections.

Before beginning the installation, you must review the aircraft type certificate data sheet and plan the system layout. Structural Requirements

due to its off-center mount point, making it a tight or impossible fit for some specific wing pods, like those on certain Cessna models. Specifications to verify: Operating Voltage: 14/28 Vdc. Approximately 9.9 lbs (10-inch) to 10.1 lbs (12-inch). Operating Temp: -55°C to +70°C. 3. Wiring and Communication Modern Garmin systems rely on high-speed data buses. The

The GWX 75 features a primary high-density connector. Wiring must comply with FAA Advisory Circular AC 43.13-1B/2B regarding aviation-grade shielding and grounding practices. Power Requirements

Once physical installation and wiring are complete, you must configure the unit using the Garmin integrated flight deck configuration mode (e.g., G1000 NXi, G3000, or GTN Xi series). Entering Configuration Mode Ensure the radar breaker is pulled.

Before opening the shipping box, prepare your workspace using the guidelines found in the :

The GWX 75 interfaces with your avionics stack via high-speed Garmin HSDB (Ethernet) or ARINC 429 networks. Clean electrical bonding is crucial to prevent RF interference. Power Requirements 14 VDC or 28 VDC nominal.

Avoid using metallic or carbon-based paints on the radome, as they attenuate and reflect radar energy back into the receiver. Use only radar-approved, non-conductive polyurethane coatings. Mechanical Alignment
