Garmin GNX 120 7_inch 安装指导

This device bridges the connection between Nexus

®

 network 

devices and a NMEA 2000

®

 network. When the device is 

connected to a computer using the included USB cable, you can 

calibrate advanced wind transducers such as the gWind Race™ 

using the NexusRace™ software, and you can use data from the 

transducers with programs such as Expedition

®

 and Adrena.

See the Important Safety and Product Information guide in the 

product box for product warnings and other important 

information.

Always wear safety goggles, ear protection, and a dust mask 

when drilling, cutting, or sanding.

When drilling or cutting, always check what is on the opposite

This device should be mounted in a location that is not exposed 

to extreme temperatures or conditions. The temperature range 

for this device is listed in the product specifications. Extended 

exposure to temperatures exceeding the specified temperature 

range, in storage or operating conditions, may cause device 

failure. Extreme-temperature-induced damage and related 

consequences are not covered by the warranty.

When selecting a mounting location, observe these 

considerations.
• To avoid interference with a magnetic compass, the device 

should not be installed closer to a compass than the 

compass-safe distance value listed in the product 

specifications.

• You can use the included screws to mount the device on 

your boat. If the included screws are not appropriate for the 

mounting surface, suitable hardware must be purchased 

separately.

Determine the mounting location.

Using the device as a template, mark the two pilot hole 

locations on the mounting surface.

Using a
