Northstar 972
according to Defense Mapping Agency
publications.
You should always be sure that the current
datum matches the chart being used. In
the 972, the datum is generally selected
automatically for the chart in use. Most
current charts use the WGS84 datum. A
few old charts from South America and
other areas use other datums. If you
choose a datum other than WGS84, an
offset will be applied, but only to the GPS
lat/lon of your vessel’s position. The vessel
will be moved on the chart, but not
waypoints, routes, or track points.
To change the datum reference:
1. On the
Navigation Options
screen, select the
Geodetic datum
option and press
Edit.
2. Press the cursor pad up or down to scan
through the alphabetic listing.
3. When you see your choice, press
ENTER
.
For a list of the available datums, Appendix
A beginning on page 155 in this manual.
NOTE:
You can specify a different datum for the
972’s output ports than the one set for the
positional display. For instructions on how to
do this, see the Northstar 972 Installation
Manual (part number GM972IM).
Entering a personalized owner’s
message
To provide your 972 with a substantial
measure of theft protection, you can enter
a personalized owner identification
message that is displayed every time the
unit is turned on. To enter or change this
message, you need an access code that
Northstar provides when you confirm
registration of your system. You can
contact customer service by phone or fax
with your registration information in order
to obtain that code. Once you’ve received
your registered-owner access code, you can
enter your owner ID message:
1. From the Display Options menu select the
Owner’s Message
option and press
Edit
.
2. Enter the access code from your Northstar
owner’s card, then press
ENTER
. The first
character block of the owner’s message
flashes.
3. Enter your message using the keypad and
cursor pad, then press
ENTER
.
Your message can be changed only by
entering your access code number and
repeating the above procedure. The 972
gives you three attempts at entering the
correct access code; after that, all opera-
tions freeze, requiring you to turn power
off, then turn it back on again to resume
functioning.
