[. . . ] The "Alert Message" controls whether or not the receiver will alert you with the beeper and a message on the display indicating a course deviation left or right in excess of the value on the scale. Parallel Track With this option, you can set a parallel track course to a destination. Useful in aviation applications where busy air corridors may dictate a parallel track, this option sets the receiver to navigate a course with a selectable course deviation distance left or right. You can select whether or not the receiver will alert you with the beeper and a message on the display indicating that this option is in use and reminding you of the course deviation. The left or right offset distance you select represents CDI mid-scale when "Parallel Track On" is set to "Yes. " D 13 Magnetic Variation This option allows you to override automatic magnetic variation and manually enter a variation value. This is normally not required for navigation anywhere in the world except near the poles, where magnetic variation is the greatest. D 14 If manual entry of magnetic variation is necessary, obtain the correct value from a reliable chart or other source. To disable magnetic variation, select "True. " All course headings will show referenced to true north. Countdown Time The Apollo handheld GPS receiver includes a countdown timer. After starting the timer, the receiver will sound the beeper and show a message on the display when the entered time has elapsed. D 15 Display Units This option allows you to change the way navigation units of measure show on the display. You can select the units shown for each navigation parameter: n n n distance: nm/kts; sm/mph; km/kph altitude: feet; meters LAT/LON: d-m. mmm; d-m-S. (where d=degrees, m=minutes, and s=seconds of latitude or longitude) Serial Outputs The Apollo handheld GPS receiver is equipped with a serial data port for communication with external serial devices. Using this option with an appropriate cable connection, you can: n n D 16 n send serial data to an external moving map display send serial data matching the NMEA formats to any serial device capable of accepting it disable the serial data port Before attempting to send serial data to an external device, use the optional serial data cable to connect the receiver to the desired device. The cable is equipped with a standard DB9 connector to fit most device serial ports. If the device has a serial port with a different connector, you need to purchase the correct connector and attach it to the cable. See "Making External Connections" at the back of this section for information on properly connecting the serial cable. Use this option to select: n n D 17 n n "None" - disable the serial port "NMEA 0183 v1. 50" - output NMEA sentences GPBWC, GPGLL, GPRMB, GPRMC, GPR00, GPWPL, GPXTE "NMEA 0183 v2. 00" - output NMEA sentences GPBWC, GPGLL, GPRMB, GPRMC, GPRTE, GPWPL, GPXTE "Moving Map" - output moving map data using Apollo NMC2001 format Battery Check This option provides a graphic indication of battery condition on a scale from "Low" to "Full. " The combined voltage of the six AA batteries is indicated at the bottom center of the screen. Also, a small battery symbol is shown at the top of the main menu indicating the battery capacity. For satisfactory receiver operation, battery voltage should be between 6 and 9 volts. You will receive a warning message on the display if battery voltage falls below 6 volts. After the warning message shows on the display, the receiver will continue to operate for 20 to 30 minutes. Replace the batteries promptly to avoid loss of time, user waypoints, routes, and system setup information stored in memory. Do not allow low or discharged batteries to remain installed in the receiver as leakage could damage internal components. D 18 User Waypoint Management This option allows you to manage the database of user waypoints. You can edit or delete waypoints as your area of travel or other requirements change. With the capacity to store up to 2, 000 user waypoints in memory, the Apollo handheld GPS receiver can retain an immense amount of information. When you edit, use intuitive identifiers for waypoints you have created. This will help you find waypoints more easily when you need to navigate to them. Use the LEFT or RIGHT ARROW keys to select "Edit" or "Del. " Select "Edit" and press the ENTER key to edit existing waypoints. Use the ARROW keys to select and change the waypoint identifier and/or position. D 19 Edit the waypoint information as required. Press the ENTER key to save the waypoint information. [. . . ] IFR: Instrument Flight Rules INT (Intersection): A point defined by any combination of courses, radials, or bearings of two or more navigational aids. LAT (Latitude): Any line circling the earth parallel to the equator, measured in degrees, minutes, and seconds north and south of the equator. G 4 LON (Longitude): Any line from the north to the south pole, measured in degrees, minutes, and seconds of a circle, east or west of the Prime Meridian, which runs approximately through Greenwich, England. Magnetic North: The region, some distance from the geographic north pole where the earth's magnetic lines concentrate. [. . . ]
