A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION This GPS receiver, (like all GPS 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 beturned off oraccuracy can be degraded at will by the system operators. Re member that the UltraNav II, or any GPS receiver is only as accurate as the system it’s using.

This code is of interest only to the service department. However, the UltraNav II interprets this code and displays a status message. This message is either “GPS MODULE PASSED” or “GPS MODULE FAILED” and shows at the bottom of the screen. The current software version number also appears near the bottom of the screen. Contact the factory customerservice department if the modulefails the self test. Do not attempt to use this product if it fails the self test. To use the self test feature, press the MENU key twice while it’s in the GPS mode, then press the key next to the “GPS MODULE SELF TEST’ label. The screen shown below appears. To exit from this screen, press the CLEAR key. GPS SIMULATOR This feature places position and navigation data on ail screens, including the plotter. The unit “navigates” a closed course. It shows bearing and distance to go, course over ground, and other information. A recurring message appears, alerting you that the simulator mode is enabled. Don't navigate when the simulator is on! To turn the simulator on, press the MENU key twice, then press the key next to the “GPS SIMULATOR OFF ON” label. The simulator mode starts immediately. To turn the simulator off, either press and hold the OFF key or repeat the above steps. Press the key next to the “GPS SIMULATOR OFF ON” label. 1 : :• GPS SELF ■ TEST v; 1 BIT SUMMARY 0000 LOW ORDER RAM FFFF HIGH ORDER RAM FFFF PRE PROCESS TEST 0000 PRE PROCESS RAM FFFF MULTI INTERFACE 0000 UCÜ TEST 0000 SIGNAL INJ. 0000 SOFTWARE UERSION r m rAD 1 -____— 3.20 78 TABLE OF CONTENTS INTRODUCTION.............................................................................................................................. 1 MOUNTING.......................................................................................................................................1 POWER CONNECTIONS.................................................................................................................£ GPS MODULE INSTALLATION........................................................................................................3 TRANSDUCER..................................................................................................................................6 KEYBOARD BASICS........................................................................................................................6 DISPLAY..................................................
