[. . . ] INSTRUCTION MANUAL Meade #1697 Computer Drive System ® For LXD 650 and LXD 750 Equatorial Mounts Meade Instruments Corporation MEADE LIMITED WARRANTY Every Meade telescope, spotting scope, and telescope accessory is warranted by Meade Instruments Corporation ("Meade") to be free of defects in materials and workmanship for a period of ONE YEAR from the date of original purchase in the U. S. A. Meade will repair or replace a product, or part thereof, found by Meade to be defective, provided the defective part is returned to Meade, freight-prepaid, with proof of purchase. This warranty applies to the original purchaser only and is non-transferable. Meade products purchased outside North America are not included in this warranty, but are covered under separate warranties issued by Meade international distributors. [. . . ] Be sure to enter the correct local time and the observing site's latitude and longitude before beginning. The following procedure should be performed in two or three 15 minute intervals. At each interval the telescope will slew to the area where the pole star should be centered in the optics. The - 12 pole star may be somewhat off-center in the eyepiece, showing that an alignment error was made during the initial setup. Using the Latitude adjustment knob and Azimuth control knob on the LXD Equatorial Mount, center the pole star during each interval exercise, then follow the rest of the routine. From the ALIGN menu option in the TELESCOPE mode, press the ENTER key. Ignore the Keypad display instructions to return the telescope to 90 degrees in Declination and 00 HA. Instead, press the GOTO key and the CDS will slew to the calculated position of where the pole star should be. Using only the Latitude and Azimuth adjustments on the LXD Equatorial Mount, re-center the pole star in the field of view in the eyepiece. Press the ENTER key, and the CDS will slew to a bright star overhead. Center this star using the "N", "S", "E", or "W" keys and press ENTER. While waiting 15-20 minutes between alignment intervals, the telescope may be used to observe. After 15-20 minutes, repeat the process, beginning with Step 1. This process may be repeated as often as desired to obtain the highest accuracy. After each 15 minute interval, the pole star becomes more accurately centered. An optional illuminated reticle crosshair eyepiece makes the job of centering the star easy. SMART DRIVE training, set the brightness and/or the pulse rate of the illuminated reticle (see page 10, The RET Key) on the chosen guide star and practice guiding (keeping the star exactly centered in the eyepiece) for a few minutes. While in the SMART menu, move the LCD arrow to LEARN by using the PREV or NEXT key and press ENTER. Numbers appear next to the LEARN display. These numbers will begin counting down to zero. The highest number that can appear is 200. This number represents a sector of the worm wheel. [. . . ] Obtain a rough polar alignment as described in the telescope's instruction manual. Once approximate alignment has been accomplished, insert the 2x Barlow lens and the illuminated reticle eyepiece into the telescope's eyepiece holder. With the motor drive running, point the telescope at a moderately bright star near where the meridian (the north-south line passing through your local zenith) and the celestial equator intersect. For best results, the star should be located within +/­30 minutes in R. A. [. . . ]
