change the latitude from north to

south, if

necessary. Press the

key next

to the "ACCEPT" label when

you've entered the desired latitude offset.

Repeat this procedure to

the

longitude. In this

example,

we have entered .012

degrees

north lattitude

and .068

degrees east longitude as the

PCF

offset. That is the differ-

ence between the present po-

sition shown

onthe unitand our

position shown by

the chart. In

otherwords,

ourposition

shown

on the unit is 0.012 degrees

north and 0.068 degrees east

of the position shown on the

After

you've entered the desired offset, press the key next to the "PCF

OFFSET OFF ON" label. This turns the PCF correction factor that you

entered on. To leave this

screen, press the

key next to the "EXIT" label.

This returns the unitto the last used GPS screen. It also puts yourchanges

into

effect.

To turn these changes off, return to this screen and press

the

key

next to

the "PCF OFFSET OFF ON" label. Remember, Presetting

the unit also

erases any PCF offset, thereby turning

it off.

The white and green wires are for a NMEA interface and a DOPS

beacon receiver. The AccuNavll sends data to another electronic

navi-

gation devices through the white wire and receives data from a beacon

receiver

through the green wire. If the white and green wires are not

used, tape

their ends so that

they

cannot short.

To connect a device to the AccuNav's white or green wires, attach a

shielded, twisted pair

cable

from the device's NMEA intput to the white

wire on the AccuNav It's power cable. Solder the ground conductor of

the twisted pair

and the shield to the black wire on the

power

cable. Do

not connect the shield to the other device. See the other instrument's

manual for more wiring instructions.

See the NMEA section in this manual for more information.

GPS MODULE INSTALLATION

The GPS module can be installed on a flat surface or (with the

supplied

adapter) on a

pole. Mount the module in an area that guarantees a clear

view of the

sky

at all times. In order for the module to receive the

signals

from the satellites, it must not be obstructed. An ideal location is on a

cabin roof, or deck. The

gunhels also make

a good location. Attaching

the pole mounting adapter lets you

install the module on a one inch mast. 17mm

However, for lightning protection, the (11/16")

antenna shoutn't be the highest part

of the boat.

Surface Mounting -

With Access

If you have access underneath the

mounting surface, use the gasket

supplied with the OPS module as a

template. Drill four 5.5 mm (7/32")

holes and one 17 mm (11/16") hole

for the module's cable. Attach the

cable to the module and pass it down

through

the hole in the

gasket and the

mounting surface. Use 5 mm

screws, flat washers, and lock wash-

ers to fasten the OPS module to the

mounting surface. Route the cable to

the AccuNav II.
