1.Take the ETX from its packaging and place it on a sturdy surface. Remove the cover from the bat- tery compartment (20, Fig. 1, page 4) located on top of the drive base and carefully lift the 9v con- nector and the battery holder from the compart- ment. Insert six AA-size batteries into the battery holder, oriented as shown on the battery holder. Connect the 9v connector plug (A) to the connec- tor (B) on the battery holder. Return the battery holder to the battery compartment. Replace the cover. See page 10 for more information.

4.Press the Speed/? key (C) to accept the Sun warning. Keep pressing the ENTER key (A) until "Country/State" appears on the display. (Ignore the prompts requesting "Date" and "Time" for now

– these functions will be explained later). Use the Scroll keys (D) to cycle through the lists of Country/States, Cities, and Telescope Models. Press ENTER (A) when the correct information for each prompt displays. The display then reads "Setup: Align." See page 11 for more information.

You can now use the Arrow keys (B) to slew (move) the telescope up, down, right, or left. To change the telescope’s slew speed, briefly press the Speed/? key (C). Each press decreases the slew speed down one level, and then will cycle back to the fastest speed.

5.Tighten (to a "firm feel" only, do not overtighten) the vertical and horizontal locks (6, 9, Fig. 1). See page 5 for more information. Remove the dust cover from the end of the telescope tube. Place the MA 25mm eyepiece (A) into the eyepiece holder on the telescope and tighten the attachment thumb- screw (B) to a "firm feel" only. Make sure that the flip-mirror control (C) is in the “up” position. See page 6, for more information.
