WARNING! 
USE THIS GPS RECEIVER  ONLY AS AN AID TO NAVIGA- 
TION.  A CAREFUL NAVIGATOR  NEVER  RELYS  ON ONLY 
ONE METHOD  TO OBTAIN POSITION  INFORMATION. 
CAUTION 
This GPS receiver, (like all GE'S navigation equipment) will show 
the shortest, most direct path to a waypoint.  It provides  naviga- 
tion data to the waypoint  regardless of obstructions.  Therefore, 
the pnident navigator will not only take advantage of all available 
navigation tools when travelling to a waypoint, but will also visu- 
ally check to make certain a clear, sate path to the waypoint is 
always available. 
NOTICE! 
As of this writing, the Department  of Defense  (DOD)  has  not 
declared the GPS navigation system as operational.  The system 
is still in a testing phase.  Satellites can be turned off or accuracy 
can be degraded at will by the system operators.  Remember 
that the GlobalNav, or any GPS receiver is only as accurate as 
the system it's using. 
Features and specifications  subject to change without notice.

INTRODUCTION 
The GlobalNav represents one of the best values in GPS receiv- 
ers today.  It rivals other GPS units costing much more in both 
features and performance.  The GlobalNav offers easy-to-use 
operation at the touch of a button. 
Although  the GlobalNav  has many features and functions, the 
"soft key" menu system makes it easy to use. Above all, don't be 
afraid to try different  features  and functions on the unit.  You 
can't hurt it by pressing buttons! 
Read this manual and take ft with you the first few times you use 
It makes a great reference should you need it.  The 
your unit. 
more you know when you get to the water, the more your 
GlobalNav can do for you! 
MOUNTING 
Install the GlobalNav in any convenient location, provided there is 
clearance  behind the unit when it is tilted for the best viewing 
angle.  Holes in the bracket base allow wood screw or through- 
bolt mounting.  You may need to place a piece of plywood on the 
back of thin fiberglass panels to secure the mounting hardware. 
Make certain there is enough room behind the unit to attach the 
power and GPS cables. 
The smallest hole that will pass the GPS module's connector is 
91 16".  After drilling  the  hole,  pass the  GPS connector up 
through the hole first, then pass the power cable down through it. 
After the  cables  have  been routed, fill the hole with  a  good 
marine sealing compound.  Offset the bracket to cover the hole. 
POWER CONNECTIONS 
The GlobalNav  works  from a twelve-volt battery system only. 
You can attach the power cable to an accessory or power buss, 
however if you have problems with electrical interference,  then 
attach the power cable directly to the battery.  If the cable is not 
long enough, splice #18 gauge wire onto it.

The power cable has three wires;  red, white, and black.  Red is 
the posilive lead, black is negative or ground.  Attach the in-line 
fuse holder to the  red  lead as close to the power source  as 
I 
possible.  For example, if you have to extend the power cable to 
the battery or power buss, attach the fuse holder directly to the 
battery or power buss.  This will protect both the unit and the 
power cable in the event of a short. The white wire is for a NMEA 
interface. The GlobalNav sends data for another electronic navi- 
gation devices through this wire.  If the white wire is not used, 
tape the end so that it cannot short. 
To connect a device to the GlobalNav's  NMEA output, attach a 
shielded, twisted pair cable from the device's NMEA intput to the 
white wire on the GlobalNav'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.  The 
GlobalNav  automatically  sends  NMEA data out the while wire 
once it acquires and 'locks on" to the satellites. 
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 
gunnels also make a good location.  Attaching the pole mounting 
adapter lets you install the module on a one inch mast.  A high 
location  is preferred.  However, for lightning protection, the an- 
tenna shouln'l 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 GPS module as a template. Drill four 
7/32" holes and one 9/16" 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 #10-32 machine screws 
(not included) to fasten the GPS module to the mounting surface. 
Route the cable to the GlobalNav.

Surface Mounting - Without Access 
If you don't have access to the back side of the mounting sur- 
face1 use the "cleats" supplied with the GlobalNav.  (Note: This is 
assuming you can "snake" the module's cable to a location that is 
accessable.  A hole will still need to be drilled in the mounting 
surface for the cable.) Using the gasket as a template, mark and 
drill the 9/16" hole for the cable.  Attach the cable to the module 
and drop the other end of the cable through the gasket and down 
the hole. Place the module on the gasket.  Slide the "cleats" onto 
each end of the module and (using the cleats as templates) mark 
four holes for #10 mounting screws.  Drill the holes, then replace 
the cleats on the module and fasten them to the mounting sur- 
face with #10 screws.  Route the cable to the GlobalNav.
