you identify and find individual stars, constel- lations, and planets in the night sky in the Northern Hemisphere. Your Star Navigator’s convenient size and light weight make it easy to carry and use anywhere. Your Star Navi- gator’s features include: 16 Star Maps — divide the visible sky into understandable sections and show the names and locations of the constellations and stars within those sections. This helps you easily identify celestial objects and use them as a reference to locate planets in the night sky. Liquid-Crystal Display — shows the date and time, setup information, star map num- ber, and the names of the celestial objects the Star Navigator can help you find. Height Indicators — show the approximate viewing height (low, medium, or high) of a ce- lestial object to help you find it. LED Indicators — help locate a celestial ob- ject you are looking for on the Star Naviga- tor’s map. Indicator — appears if a celestial object you selected is viewable any time that night until dawn the next morning. Built-in Compass — helps you find the cor- rect direction to point the Star Navigator. “Navigating the Universe” Guide Book — provides valuable information about the ce- lestial objects the Star Navigator can help you find. ˆ A Quick Look at Your Star Navigator RESET IDENTIFY Display FIND Height Indicators SELECT STEP Star Map Rotation Rotational Indicators Star Map Indicators Compass Battery Ring Important: Your Star Navigator can find stars, Stand Compartment constellations, and planets and identify stars Hemisphere between the latitudes of 25° (Key West, FL) and 55° (southern Alaska). and constellations in the sky of the Northern

teries (not supplied) for power. For the best performance and longest life, we recom- mend RadioShack alkaline batteries. Cautions: • Use only fresh batteries of the required size and recommended type. • Do not mix old and new batteries. 1. While holding down the tab on the bat- tery compartment cover, pull the cover up to remove it. 2. Place the batteries in the compartment as indicated by the polarity symbols (+ and –) marked inside. 3. Replace the cover. After you install the batteries, the Star Navi- gator turns itself on and JAN (January) ap- pears, indicating it is ready to set up. When the display dims or the Star Navigator stops operating properly, wait about 1 minute for the Star Navigator to turn off, then replace the batteries. Warning: Dispose of old batteries promptly and properly. Do not burn or bury them. Caution: If you do not plan to use the Star Navigator for a month or more, remove the batteries. Batteries can leak chemicals that can destroy electronic parts. TURNING ON THE STAR NAVIGATOR Press any button to turn on the Star Naviga- tor. To save power, your Star Navigator auto- matically turns itself off if you do not press any button for about 1 minute. Note: Your Star Navigator does not turn it- self off during setup or if any of its rotational or directional indicators are on. SELECTING A LATITUDE To calibrate your Star Navigator, select the latitude of your location from one of these maps, then write it down. For example, if you live in Colorado, your latitude is 40. North America 30 Europe

maps, choose the closest latitude to your lo- cation. If your location lies between any two latitudes, choose either latitude. SELECTING A TIME CORRECTION ZONE The time zone in which you reside can affect your observations. To calibrate your Star Navigator, select the time correction zone for your location from one of these maps, then write it down. For example, if you live in Ohio, your time correction zone is M. Note: If your location is not shown on the maps, choose the closest time correction zone to your location. If your location lies be- tween any two time correction zones, choose either zone.

outdoors on a clear night, away from sources of bright light. Select a location that is in an open area with good overall visibility, without too many trees or buildings nearby, and away from metal and magnetic material. Warning: Never look directly at the sun. Tips for Better Stargazing • Wait at least 5–10 minutes after you first go outside to view celestial objects, to give your eyes time to adjust to the reduced light. • If your location is extremely dark, you might need a source of light to help you operate the Star Navigator. Use a small flashlight or penlight, with a red filter or a piece of clear red plastic over the light source. The red light helps preserve your ability to see at night. • You might not be able to see all the objects shown on the star maps at your location due to factors such as weather, atmospheric conditions, and your prox- imity to “light pollution” such as city lights, automobile headlights, or even a full moon. • Planets are generally bright and do not twinkle as much as stars, offering a steadier light. • The first few times you use your Star Navigator, find the brightest stars and most recognizable constellations first. Then look for distinctive patterns. This can help you locate some of the harder- to-see constellations. ˆ Operation FINDING A CONSTELLATION OR STAR 1. Repeatedly press FIND until CONSTL (to search for a constellation) or STARS (to search for a star) appears. 2. Refer to the tables on Pages 7 and 8 to find the abbreviation for the constellation or star you want to find. 3. Repeatedly press STEP or IDENTIFY until the desired abbreviation ap- pears. appears if the constellation or star is currently visible or will be visible later that night. does not appear if the constellation or star is not currently visi- ble and will not be visible later that night. For example, to find the Big Dipper con- stellation, repeatedly press FIND until CONSTL appears, then repeatedly press STEP or IDENTIFY until BIGDIP appears. 4. If appears, press SELECT. If the con- stellation or star is visible, a rotational indicator on the front of the Star Naviga- tor flashes, one of the star map indica- tors on the back of the Star Navigator flashes, and MAP and a map number appear. Otherwise, the time or date Summer Virgo, Scorpio, Sagittarius, Lyra, Cygnus, Big Dipper Autumn Cygnus, Pegasus, Scorpio, Sagittarius, Big Dipper, Lyra Winter Pegasus, Auriga, Taurus, Canus Minor, Orion Season Visible Constellations

ible appears. Note: If does not appear and you press SELECT, the date that the constel- lation or star will be visible or the time the next night when it will be visible appears. The constellation or star you selected will not be visible that night. Press STEP to return to the constellation or star list, select another constellation or star, then start over at Step 2. 5. If the star/constellation is currently visi- ble, turn the Star Navigator over and carefully remove the star map whose indicator is flashing from the holder. Then insert the star map into the rotation ring on the front panel between the body of the Star Navigator and the back of the ring. Note: Make sure the star map’s notch fits properly into the rotation ring’s tab. 6. Rotate the ring until its tab covers the flashing rotational indicator. The star map now matches the orientation of the sky. 7. Press SELECT. A directional indicator and a height indicator flash, and TURN appears. 8. Hold the Star Navigator flat, then stand in the same place while you slowly turn your body until the compass’ arrow points to the flashing directional indica- tor. You are now facing in the correct direction. 9. Raise your head to the level shown by the flashing height indicator (HIGH, MID, or LOW). Then lift the Star Navigator until it is directly under your line of sight 10. Press SELECT. LOOK appears and the star map brightens. The directional and rotational indicators turn off. Red stars and red lines appear on the star map. Compare the stars in the sky with the stars on the star map. Notes: • If necessary, repeatedly press IDEN- TIFY to adjust the display’s bright- ness. • The star map does not light during daylight hours or when constellations on the map are not visible in the night sky. 11. Press STEP. The green lines on the star map light, showing you the shape of the constellation as the ancient Greeks and other civilizations pictured it. 12. Press STEP again to turn off the green lines. 13. Press SELECT to return to the abbrevia- tion of the star or constellation you are viewing, then press FIND. READY appears. FINDING A PLANET 1. Repeatedly press FIND until PLANET appears. LOW MID HIGH

abbreviation for the planet you want to find. 3. Repeatedly press STEP or IDENTIFY until the desired abbreviation ap- pears. appears if the planet is cur- rently visible or will be visible later that night. does not appear if the planet is not currently visible and will not be visi- ble later that night. For example, to find Mars, repeatedly press FIND until PLANET appears, then repeatedly press STEP or IDENTIFY until MARS appears. 4. If appears, press SELECT. If the planet is visible or just rising, a rotational indicator on the front of the Star Naviga- tor flashes, one of the star map indica- tors on the back of the Star Navigator flashes, and MAP and a map number appear. Otherwise, the time when the planet will be visible appears. Note: If does not appear and you press SELECT, you see any of the follow- ing: • NOTVIS appears. The planet you selected is not visible and will not be visible that night. • appears, a rotational indicator on the front of the Star Navigator flashes, one of the star map indica- tors on the back of the Star Navigator flashes, and MAP and a map number appears. The planet you selected is still visible but just setting. • and the time the next night when it will be visible appears. The planet you selected has already set and will not be visible that night. Press STEP to return to the planet list, select another planet, then start over at Step 2. 5. Turn the Star Navigator over and care- fully remove the star map whose num- ber is flashing from the holder. Then insert the star map into the rotation ring on the front panel between the body of the Star Navigator and the back of the ring. Note: Make sure the star map’s notch fits properly into the rotation ring’s tab. 6. Rotate the ring until its tab covers the flashing rotational indicator. The star map now matches the orientation of the sky. 7. Press SELECT. A directional indicator and a height indicator flash, and TURN appears. If the object is just rising in the sky, RISING also appears. 8. Hold the Star Navigator flat, then stand still while slowly turning your body until the compass’ arrow points to the flash- ing directional indicator. You are now facing in the correct direction. 9. Raise your head to the level shown by the flashing height indicator (HIGH, MID, or LOW). Then lift the Star Navigator until it is directly under your line of sight 10. Press SELECT. The name of the constel- lation where the planet is in or near appears and the star map brightens. 11. Compare the stars in the sky with the stars on the star map. Any bright “star” in the sky that does not match the stars on the star map you are looking at and does not move is the planet you are looking for. Notes: • If necessary, repeatedly press IDEN- TIFY to adjust the display’s bright- ness.

daylight hours or when constellations on the map are not visible in the night sky. 12. Press SELECT to return to the list of planets. IDENTIFYING A STAR OR CONSTELLATION If you see a star or constellation you cannot identify, you can use the Star Navigator to confirm its name. Note: If you try to use your Star Navigator during the day (when celestial objects are not visible), DAYTIM appears. 1. Hold the Star Navigator flat, then turn your body to face the object you want to identify. 2. Repeatedly press FIND until READY appears. 3. Press IDENTIFY. MAP and a map number appear. Then, a rotational indicator, directional indicator, and height indicator on the front of the Star Navigator flashes and one of the star map indicators on the back of the Star Navigator flash. 4. Repeatedly press IDENTIFY until the directional indicator closest to the point of the arrow on the compass flashes. A new map number appears and its indi- cators flash. 5. Confirm if the height of the object you want to identify matches the height indi- cated by the flashing height indicator. If they do not match, press IDENTIFY again. Note: If the heights do not match exactly, compare the object you are viewing with different star maps while looking in the same direction. In some cases, you might have to compare more than one star map. 6. Turn the Star Navigator over and care- fully remove the star map whose indica- tor is flashing from the holder. Then insert the star map into the rotation ring on the front panel between the body of the Star Navigator and the back of the ring. Note: Make sure the star map’s notch fits properly into the rotation ring’s tab. 7. Rotate the ring until its tab covers the flashing rotational indicator. The star map now matches the orientation of the sky. 8. Slowly turn your body until the compass’ arrow points to the flashing directional indicator. You are now facing toward the center of the star map. 9. Raise your head to the level shown by the flashing height indicator (HIGH, MID, or LOW), then lift the Star Navigator until it is directly under your line of sight. 10. Press SELECT. LOOK appears and the star map brightens. Red stars and red lines appear on the star map. Compare the object you want to identify with the objects on the star map. Notes: • If necessary, repeatedly press IDEN- TIFY to adjust the display’s bright- ness. • The star map does not light during daylight hours or when constellations on the map are not visible in the night sky. 11. Press STEP. The green lines on the star map light, showing you the nearby con- stellations, stars, and planets. 12. Press STEP again to turn off the green lines. 13. Press SELECT. READY appears.

at different locations on earth can affect your Star Navigator’s compass readings, making it more difficult to find celestial objects. If you have trouble finding celestial objects, use the maps shown in “Selecting a Magnetic Cor- rection Zone” on Page 13 to find the adjust- ment (if any) you must take to find the correct direction in which to stand to view celestial objects. Selecting a Magnetic Correction Zone Each magnetic zone map is divided into three parts – LED, TURN LEFT, and TURN RIGHT. If your location lies within a part of the map labeled LED in the maps on the right, you should not need to make any corrections for magnetic variations. Face in the direction of the object you want to find as closely as pos- sible, then simply turn your body until the compass’ arrow points directly to the flashing directional indicator. If your location lies within a part of the map labeled TURN LEFT, you must make a cor- rection for magnetic variations. Turn your body until the compass’ arrow points directly at the flashing directional indicator. Then turn your body slightly to the left so the compass’ needle points to the I indicator. If your location lies within a part of the map labeled TURN RIGHT, turn your body until the compass’ arrow points directly at the flashing directional indicator. Then turn your body slightly to the right so the compass’ needle points to the II indicator. Note: Your Star Navigator’s compass is de- signed so the letter closest to you (in the six o’clock position) indicates the direction you are facing.
