Garmin VHF 110 Marine Radio Installation Instructions - Page 2

6 After the device fits correctly in the cutout, ensure the mounting holes on the device line up with the pilot holes on the template. 7 If the mounting holes on the device do not line up, mark the new pilot-hole locations. 8 Using a 3.5 mm (9/64 in.) drill bit, drill the pilot holes. 9 Remove the template from the mounting surface. 10 If you will not have access to the back of the device after you mount it, connect all necessary cables to the device before placing it into the cutout. 11 If necessary, cover unused connectors with the attached weather caps to prevent corrosion of the metal contacts. 12 Install the foam gasket on the back of the device. À The pieces of the rubber gasket have adhesive on the back. Make sure you remove the protective liner before installing them on the device. Item Description Ground À connection Power, NMEA® Á 0183, and speaker wiring harnesses VHF antenna  connection Additional à microphone connector NMEA 2000® Ä connector Notes You can use the included grounding screw to connect the device chassis to water ground, if needed (Additional Grounding Considerations, page 2). You must connect the device to a 12 Vdc power source (Connecting the Wiring Harness to Power, page 2). You can connect this device to a NMEA 0183 device using this wiring harness to share DSC and GPS information (optional) (NMEA 0183 Device Connections, page 3). You can connect this device to a hailer horn using this wiring harness (optional) (Connecting to a Hailer Horn or PA Speaker, page 3). You can connect this device to an external speaker using this wiring harness (optional) (Connecting to an External Speaker, page 3). You must connect the device to a VHF antenna (sold separately) (Connecting a VHF Antenna, page 2). You can add an additional microphone (sold separately) or relocate the existing microphone on a VHF 210 AIS radio (microphone relocation kit sold separately). This connector is not available on a VHF 110 radio. You can connect this device to a NMEA 2000 network on your boat to share DSC and GPS information (optional) (NMEA 2000 Device Connections, page 2). 13 Place the device in the cutout. 14 Secure the device to the mounting surface using the included screws . Á 15 Install the decorative bezel by snapping it in place around the edges of the device. Mounting the Microphone Hanger NOTICE If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer when the screws are tightened. Stainless-steel screws may bind when screwed into fiberglass and overtightened. It is recommended to apply an anti-seize lubricant on the screws before installing them. You can mount the microphone hanger in a convenient location near the radio. 1 Select a mounting location for the microphone within reach of the microphone cable. 2 Using the microphone hanger as a template, mark the pilot holes. À 3 Drill the mounting holes using a 3 mm (1/8 in.) drill bit. 4 Secure the microphone hanger to the mounting surface using the included screws . Á Connection Considerations Connecting the Wiring Harness to Power 1 Route the wiring harness to the power source and to the device. 2 Connect the red wire to the positive (+) battery terminal, and connect the black wire to the negative (-) battery terminal. Additional Grounding Considerations This device should not need any additional chassis grounding in most installation situations. If interference is experienced, the grounding screw on the housing can be used to connect the device to the water ground of the boat to help avoid the interference. Connecting a VHF Antenna 1 Mount the VHF antenna (sold separately) according to the installation instructions provided with the antenna. 2 Connect the VHF antenna to the antenna port on the back of the radio. NMEA 2000 Device Connections NOTICE If you are connecting this device to an existing NMEA 2000 network, the NMEA 2000 network should already be connected to power. Do not connect the NMEA 2000 power cable to an existing NMEA 2000 network, because only one power source should be connected to a NMEA 2000 network. If you are connecting this device to an existing NMEA 2000 network or engine network by another manufacturer, you should install a NMEA 2000 Power Isolator (010-11580-00) between the existing network and the Garmin devices. If you are installing a NMEA 2000 power cable, you must connect it to the boat ignition switch or through another in-line switch. NMEA 2000 devices will drain your battery if the NMEA 2000 power cable is connected to the battery directly. To connect this device to your existing NMEA 2000 network, you must purchase a NMEA 2000 cable and connector. If you are unfamiliar with NMEA 2000, you should read the "NMEA 2000 Network Fundamentals" chapter of the Technical Reference for NMEA 2000 Products. Go to www.garmin.com/manuals/VHF_110_210/. 2
