[. . . ] Instruction Manual LXD55-Series Telescopes Meade Instruments Corporation CONTENTS WARNING! Never use a Meade® LXD55-Series Telescope to look at the Sun!Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope or its viewfinder at or near the Sun. [. . . ] Custom: Allows entry of user-defined tracking rates. Reverse L/R: Reverses the functions of the Left and Right Arrow keys (i. e. , the Right key moves the telescope to the left). Reverse U/D: Reverses the functions of the Up and Down Arrow keys (i. e. , the Up key moves the telescope down). Calibrate Motor: If the telescope motors appear to have a problem, use this option to retest the motors before performing a Reset. This option is also used if an Autostar unit is moved between telescopes, to match Autostar to the new telescope. To calibrate the motors, select this option and press ENTER. High Precision: If High Precision is turned on, when looking for a faint celestial object (i. e. , a nebula or galaxy), Autostar first slews to a nearby bright star and displays "ENTER to Sync. " Center the star in the eyepiece, then press ENTER. At that point the telescope has a high precision alignment to that part of the sky and it then slews to the object that was originally requested. b. Tip: If the "ENTER to Sync" feature is accessed by mistake (holding the ENTER key for more than 2 seconds), press MODE to return to the previous screen. s Targets switches between Astronomical targets and Terrestrial targets. If "Astronomical" is selected, the telescope tracking motor is activated and any object you observe will remain centered in the eyepiece. If "Terrestrial" is selected, the tracking motor is turned off. To learn how to track an object automatically, see page 18. Site provides access to several options including: s Select: Displays the currently selected observing site. Use the Scroll keys to cycle through all available sites (see ADD below). Press ENTER when the site you wish to select displays. Use this option when you move to a different geographic location.

Scroll through the list of Countries/States. Press ENTER when the site you wish to add displays. Then choose the desired city in the same manner. Delete: Deletes a stored site from the database. Edit: Edits a selected site, including: the name, latitude, longitude, and time zone. Time Zone refers to the Greenwich Mean Time (GMT) time zone shift.
