Turn the unit off and back on to reset. • Simulating Navigation—The receiver is in simulator mode (page 23). GPS accuracy information is indicated along the bottom of the screen. • Accuracy—indicates the approximate accuracy of the unit. • DGPS Rcvr—indicates the status of the DGPS receiver (page 16). GPS 152H Owner’s Manual 1 Settings • DOP (Dilution of Precision)—displays DOP, which is an indication of satellite geometry quality measured on a scale of one to ten. Lower numbers indicate higher quality signals. • DGPS SNR—displays the SNR when the unit is receiving a DGPS signal. The SNR range is 0dB to 30dB, with 30dB being the best. WAAS (Wide Area Augmentation System) can provide more- accurate GPS position information in North America. However, when using WAAS, the device takes longer to acquire satellites. To disable WAAS: 1. From any Main page, press Menu twice and highlight GPS. 2. Press Menu, and select Disable WAAS. When your unit is turned on, it starts the search for your location based on where you were when it was turned off. AutoLocate is used by the GPS 152H to find your location when the unit does not know your previous location. To use AutoLocate to find your location: 1. From any Main page, press Menu twice and highlight GPS. 2. Press Menu, and select AutoLocate. You can manually enter your altitude when in 2D navigation or simulator mode. Any altitude entered will be automatically calculated when the unit is in 3D navigation mode. To set 2D altitude: 1. From any Main page, press Menu twice and highlight GPS. 2. Press Menu, and select 2D Altitude. Using the Tide TabFrom any Main page, press Menu twice and highlight Tide. The Tide tab shows a chart that displays tide station information in a 24 hour span, starting at midnight station time. You can select different dates. 1 GPS 152H Owner’s Manual Settings The top of the screen displays the tide station. The top of the chart shows a 24-hour block of local time (LCL) for your position, with the reported station time (STA) appearing at the bottom. The solid, light vertical lines are in 4-hour increments, and the light, dotted vertical lines are in 1-hour increments. A dark, vertical line indicates the current time. High tide Maximum tide level Present tide level Minimum tide level Present t me Low tide The four data fields below the chart indicate event times and levels at which the tide changes. To view tide information for a different date: 1. From any Main page, press Menu twice and highlight Tide. 2. Press Menu, and select Modify Station Opt. 3. Select the Date field and enter text as described on page 2. To select the tide station nearest your location: 1. From any Main page, press Menu twice and highlight Tide. 2. Press Menu, and select Nearest Tide Station. The name of the nearest tide station appears along the top of the screen. Note: You must be within 100 nautical miles of a tide station to use this feature. GPS 152H Owner’s Manual 1 Appendix Appendix Specifications Physical Specifications Size : W . H .
