7.Replace the Declination slow-motion knob (2), Fig. 2. Lock in place by tightening the set screw, and replace the rubber knurling.

8.Remove the cover plate on the opposite side of the Declination housing, by removing the four Phillips-head screws holding it in place.

9.Route the 16-pin ribbon cable from the Driver PCB so that it exits the housing on the lower right-hand side. Be sure this cable does not cover the hole in the Declination shaft, which will block light from reaching the optional #814 Polar Alignment Finder should one be installed.

10.Connect the 16-pin ribbon cable (2), Fig. 4, to the CDS PCB (1), Fig. 4.

11.To position the CDS PCB into the Declination casting, first angle the top of the PCB into the opening, allowing it to clear the housing. Then, tilt the lower section of the CDS into the housing. Secure the CDS in place with the four screws.

12.Plug the RA motor coil cord into the R.A. motor port (8), Fig. 5 on the CDS Power Panel.

13.Plug the #1697 Keypad Hand Controller into the keypad port (7), Fig. 5, on the CDS Power Panel.

14.Plug in one of the provided power supplies: the AC Wall Adapter Power Converter, or the DC Cigarette Lighter Power Cord (used in an automobile's cigarette lighter outlet). The power supply plugs into the power port (9), Fig 5.

Installation of the #1697 CDS is now complete.

Basic Telescope Setup:

1.Polar align your telescope. See the instructions that accompany the telescope.

2.Turn "on" the #1697 Control Box. The Keypad Display (1), Fig. 6, displays “MEADE” for several seconds as the micro- processor does a self-diagnostic test. When the self- diagnostic test is complete, the display shows “TELE- SCOPE” on the top line, and “OBJECT LIBRARY” on the lower line. The Speed Indicator LED (3), Fig. 6, next to the “SLEW” button is illuminated.

QUICK START

Although the electronics within the #1697 Computer Drive System are advanced, the system is very straightforward to operate—even for the beginning observer. This section is designed as a "quick start" section for those observers anxious to begin. Be sure to come back and read the more detailed sections of this manual. Most of the system’s features cannot be accessed without full knowledge of these details.

3.At this point, the #1697 Computer Drive System is ready to use. Select a speed at which to move the telescope by pressing the appropriate Speed Selection Key (4), Fig 6. As a speed is selected, the red LED next to the selected speed lights up. Then press one of the four direction keys, (2), Fig. 6, to move the telescope in that direction at the selected speed.

4.With the CDS power turned on, the LXD mount can be moved in either of two ways: (1) By loosening the R.A. and Dec locks as described in the instruction manual supplied with your telescope; or (2) by using the N, E, W, or S keys (2), Fig. 6, on the Keypad.

NOTE: Telescope movement can only been seen in the SLEW and FIND modes; CNTR (center) and GUIDE motions can only be seen while looking through the telescope.

DO NOT attempt to adjust the LXD Equatorial Mounts with the manual R.A. or Dec slow-motion controls when the CDS Drive is turned on. Serious damage to the drive motor assemblies could result.

Please note that it is possible for the telescope to hit one of the tripod legs while manually moving the LXD Equatorial Mount with the Keypad direction keys. The CDS software is programmed, however to avoid hitting the tripod legs provided the proper time, date, and site information has been entered, and that the telescope has been properly aligned, as described on page 7.

The quick start method described above allows you to use the telescope, but does not make any use of the computer features available. To utilize all the features of the #1697 Computer Drive System, it is necessary to enter some information into the
