requires only

the appears.To select a radius, simply press

the

key adjacent to the up or

entry

of the

present position

from the

operator. You don't have to know

which stations

are best

or the

CR1 to use the initial position only startup.

However,

when the Z-9500 is in the automatic mode, it can change

stations

at any time if it decides one or more stations are better to use

than others. This can result in small position inaccuracies. For ex-

ample, suppose you use the bran one day and save a waypoint. The

day you decide to navigate

to that waypoint. If the Z-9500 uses

different set of stations on the second

day than the ones used

on the

first, you could end up at a location that is a small distance away

from

the desired

one. You can avoid

this by switching the Z-9500 into the

manual mode after

it has locked on to the stations in the

chain and has

both a good fix and shows a position. Using the manual mode forces

the unit to use the ones it is currently using

or ones you choose. (See

the Manual Station Selection section for more

information.)

GRI ONLY INITIALIZATION

This method of starting

the Z-9500

requires the most

thought

from the

user. Not

only

will

you need to select

the best SRI to use for

your

area,

but you will also have to choose the stations for the Z-9500 to use.

Using

the SRI only method forces the Z-9500 into the manual mode.

PRESENT POSITION AND GRI INITIALIZATION

Giving

the Z-9500 both your present position and the SRI typically

lets it

find the stations faster. Therefore,

it can give you a position faster

using

this initialization procedure. However, you may

need to select

stations,

since the unit could start in the manual mode.

The reason for this is there are areas of the world that are covered

more than one CR1. One of the GRIs is better to use than the others

(depending on your location), due to crossing angles and signal

strengths. If the SRI you enter happens

to be the preferred SRI for

your location, the Z-9500 will switch to automatic and choose the sta-

tions to use. If the SRI is not preferred, then the unit will switch to the

manual mode and

you will have to choose the stations. Based upon

the

SRI used, you can always

switch the Z-9500 into the manual mode, but

you can't

always

use automatic.

Plotter

Update

Interval

The

plotter

shows your

track

by drawing a solid line behind your present

position. When the unit is turned on for the

very

first time, the position is

updated

once every ten seconds. You can vary this time from 2 sec-

onds to 20 minutes.

As each dot is

on the track

line, one is erased from

the end after

a certain length has been achieved. This shortens the plotted line, but

still shows the

you plot a course that's a long

WAYPOINT NAVIGATION

HOW TO SAVE A WAYPOINT

Waypoints are locations that you save in the Z-9500's memory. You

can then navigate to these positions using

the Steer

Indicator, Naviga-

tion, or Plotter screens. Waypoints are useful

for marking shipwrecks,

hot fishing spots, and other fishing or navigational locations. The Z-

9500 can store

to 75

waypoints. You can store

your present position

as a

waypoint, or enter TD's or latitude/longitude positions.
