[. . . ] Proper orientation of bracket when attached to telescope's focuser. Before the focus motor can be attached to the bracket, the cover plate on the right-hand focus knob (when looking directly down the focuser) must be removed. This is best done with a flat-head screwdriver. Wedge the screwdriver under the cover plate to remove it (see Figure 3). [. . . ] This can easily be done by prying the tab that protrudes from the cover plate on the bottom of the hand controller. Insert the batteries into the battery compartment in the proper orientation, as shown in the diagram engraved in the bottom of the battery compartment. The batteries should now be properly installed. To check that this is the case, push one of the buttons on the front of the hand controller. You should hear the focus motor turning. If you don't, remove the cover plate and check that the batteries are properly placed in the battery compartment. Installing the Electric Focuser on the Telescope Focuser To install the Electric Focuser, the focus motor bracket must first be attached to the underside of the telescope's focuser. Locate the cover plate that goes over the pinion gear of the telescope's focuser (see Figure 1). The open end of the bracket fits directly over the cover plate; position the bracket so the exposed shafts of the focuser's pinion gear line up with the slots in the open end of the bracket. Also, orient the bracket so the notch in the closed bottom end faces to the IN 111 Rev. A 0199 Operation Using the Electric Focuser is easy. While looking into an eyepiece held in the focuser, simply depress the push-buttons on the hand controller (one at a time!). The button on the left side of the controller racks the focuser drawtube in, while the button on the right racks it out. There are no "on/off" switches to worry about; the motor is always turned off until one of the buttons is pressed. Push the buttons until an approximate focus point is found. Then push the appropriate button to go just through the actual focus point. Now, use the other button to get back to the exact focus point. The motor takes a second to reverse directions, so keep that in mind when making fine adjustments. If manual focusing is needed, the button on the outside of the motor housing serves as a release clutch (Figure 4). Simply press the button, then while it is depressed, turn the focus knob on the left side of the focuser. Releasing the clutch button will revert the system back to electric focusing. Care and Maintenance When not in use, the Electric Focuser can be either removed and stored, or left on the telescope. [. . . ] The electric focuser properly installed. Figure 3.
