NOTES: WARNING! USE THIS GPS RECEIVER ONLY AS AN AID TO NAVIGATION. A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION This GPS receiver, (like all OPS navigation equipment) will show the shortest, most direct path to a waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigator will not only take advantage of all available navigation tools when travelling to a waypoint, but will also visually checkto make certain a clear, safe path to the waypoint is always available. NOTICE! As of this writing, the Department of Defense (DOD) has not declared the GPS navigation system 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. Rememberthat the GlobalNav II, or any GPS receiver is only as accurate as the system it's using.

Using menu features and "soft-ke?' operation, the GlobalNav Ills also one of the easiest-to-use products that Lowrance has ever built. The wide "Clearvision" screen shows the navigation and plotter screens with high resolution and detail. The display and keyboard are also lighted for night operation. Read this manual and take itwith you thefirstfewtimes you use your unit. It makes a great reference if you need it. MOUNTING - Bracket Mount Install the GlobalNav II in any convenient location, provided there is clearance behindthe unitwhen it istilted forthe bestviewing angle. Holes in the bracket base allow wood screw orthrough-bolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panels to securethe mounting hardware. Make certain there is enough room behind the unit to attach the power and GPS module cables. The smallest hole that will pass one power or transducer plug is one inch. Afterthe hole is drilled, passthe OPS connector up through the holefirst, then pass the power cable down through it. Afterthe cables have been routed, fill the hole with a good marine sealing compound. Offsetthe bracketto coverthe hole. Routethe powerand OPS module cables through the slot in the back of the bracket. PDF compression, OCR, web-optimization with CVISION's PdfCompressor 46 1 GROUP "F" GROUP 'G"

IN-DASH MOUNTING The GlobalNav II can be installed in the dash with the supplied hardware if the dash is 1/2" thick or less. Determining the dash thickness can be difficult, however, if you remove a gauge from the dash, you can easilly measure the thkness.

Measure carefully before cutting! After culling the dash, place the gasket supplied with the GlobalNav II around the unit and place the unit in the hole. Supplied with the GlobalNav II are rubber pads, bolts, washers, and cam clamps to attach it to the dash. Peel the adhesive backing off the rubber pads and place one on each side of the unit in the location where the cam clamp will touch the back side of the dash. Using the hardware supplied with the unit, attach the unit to the dash. Make certain that the cam clamp on the left side of the unit is pointing down and the cam clamp on the right side of the unit is pointing up before you start tightening the bolts. RUBBER PAD !

the chart. For this reason, you should be careful when enter- ing the PCF offset. This offset is saved in memory. It doesn't change when the unit is turned off. However, a Preset does erase the PCF factor. To set the PCF factor, first press the MENU key, then press the key next to the "Change GPS Settings" label. "PCF Offset" label. The screen shown N o°uaoou' Now press the key next to the above appears. Now pressthe key adjacent to the "Change Offset' label to enter the correction factor for your location. The screen shown at right appears. Re- member, this is the difference between the location shown on the presentposition display and the position shown on the chart. Use the arrow keys to move the black box to the number that you wish to change in the latitude, then enterthe numbers. Press the key next to the "Latitude N 3" to change the latitude from north to south, if necessary. Press the key next to the "Accept Offset" label when you've entered the desired latitude offset. Repeat this procedure to change the longitude. Inthis example, we haveentered Odegrees,.012 minutes north lattitude and 0 degrees, .068 minutes east longitude as the PCF offset. That is the differ- ence between the present po- sition shown on the unit and ourposition shown bythe chart. In other words, our position shown on the unit is 0.012 min- utes north and 0.068 minutes east of the position shown on the chart. N 0000.012 POWER CONNECTIONS The GlobalNav II works from a twelve-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it's saferto go ahead and attach the power cable directly to the battery. If the cable is too short, splice #18 gauge wire onto it. The power cable has four wires; red, black, green, and white. Red is the positive lead, black is negative or ground. Make certain to attach the in-line fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the powercabletothe battery orpowerbuss, attach one end of thefuse 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 GlobalNav II uses a 3-amp fuse. Do not use this product without a 3-amp fuse wired into the power cablel Failure to use a 3-amp fuse will void your warranty.

The white and green wires are for a NMEA interface. The AccuNavil sends data to another electronic navigation devices through the white wire and receives NMEA data through the green wire. If the white and green wires are not used, tape their ends so that they cannot short. Tu uuIIlIeei d deviuw u ilie GiobuiNavs NMEA output, auacn a shielded, twisted pair cable from the device's NMEA intput to the white wire on the GlobalNav Ii'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 OPS 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. However, for lightning protection, the antenna shouln'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 GPS 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 washers to fasten the OF'S module to the mounting surface. Route the cable to the GlobalNav II. 17mm (11/16') Hole (4 places) 5.5mm (7/32") \[ , DECK7 5MM SCREWS : BACK LIGHT ON/OFF To turn the back lighting on, pressthe menu key, then press the key nexttothe "More" label twice. Now press the key adja- cent to the back igni On Oft label. This moves the black box from "OFF" to the "ON" posi- tion. To turn the backlights off, repeat the same steps. SPEAKER VOLUME The speaker volume has two levels: high or low. When the GlobalNav II is first turned on, the speaker volume is high. To change it, pressthe MENU key, then pressthe key next to the "More" label twice. Now press the key next to the "Speaker Volume Low High" label. This switches the volume from high to low. A short tune sounds, letting you hear the volume. To switch back to high volume, simply press the key again. To exit from this menu, press the CUR key. PCF OFFSET The GPS navigation system relies on complex mathematical calculations to determine your position based on satellite data and other factors. One factor is the Earth's shape. Since the Earth is not a true sphere, variations in the calculations have to be made to accommodate deviations. To make matters more complex, not everyone uses the same data to determine what the deviations are. The size and shape of the ellipsoids that are used to approximate the earth's surface are improved often. This can lead to errors if your navigation device uses one ellipsoid, while your chart uses a different one. The term used for these ellipsoids is "Datum." To reducethe errorfactorbetween datum, this unit gives you the capability to move or "offset" the position shown on the display to match the one on the chart. The unit will add this offset to all position displays at all times. For example, suppose you are anchored at a location that is accurately marked on a chart. Your unit shows a longitude position that is .010 degrees less than the one on the chart. Using the Position Correction Factor (PCF) Offsetfeature, you makethe unit read the same asthe chart. If you raise anchor and move, the unit will continuously add the change to all position displays. This makes it more closely match the datum used by PDF compression, OCR, web-optimization with CVISION's PdfCompressor 45 4
