required. When using the Trim Ring Kit, add

3/4”

to the width and height

clearance dimensions.

CAUTION

Make sure there are no hidden electrical wires or other items behind the

desired location before proceeding. Check to see that free access for mount-

ing and cabling is available.

2.Using the dimensions for the cutout hole shown,

draw the pattern for the cutout hole on the console.

3. Drill two l/2” pilot holes inside the cutout guide

area at diagonal corners.

4. Using an appropriate saw, cut along the outside

of the cutout line.

5. Remove the yoke knobs and the yoke and the rubber spacers from the

cabinet. If using the Flush Mount Kit verify that the unit fits correctly into

the cutout. If using the Trim Ring Kit, attach the Trim Ring, then test fit into

the cutout. It may be necessary to notch out some clearance in the cutout to

pass the trim ring hardware through the panel.

7. Complete the installation of the DC power cable, data output, and sensor

wiring into the console as per section 2.4 of this chapter. Be sure to allow

some slack in the cables for service to the equipment when necessary.

8. Connect all cables to the unit rear panel.

9. Insert the NAV unit into the panel. Use a flat washer, locking washer,

and nut on each stud and secure to the console. In some cases you may prefer

to apply a light coat of RTV sealant around the cutout to seal the console.

2.3 Electrical Connections

The standard connections which are

normally made to enable the

NAV 398

to operate are the ship’s DC power, to

either a Raynav 508 or 508A Loran-C

sensor or to a Raystar 108 GPS sensor

or both. The NAV unit can also supply

NMEA data to other equipments. The

next sections discuss how to make NMEAj!EATALK

these connections.
