Remove the ETX from its packaging and place it on a
sturdy surface. Place the eyepiece (A) and viewfinder
(B) into their appropriate positions on the telescope
and tighten the appropriate attachment screws to a
firm feel only.
Securely place the ETX on its side and remove the
battery compartment cover (C) from the underside of
the drive base. Insert eight (user-supplied) AA-size
batteries into the battery compartment (D) in the
proper orientation. Replace the cover and return the
telescope to an upright position.
Verify that the computer control panel power switch (E)
is in the OFF position. Remove the Electronic
Controller (F) from the packing materials and plug it
into the HBX port (G). Tighten the vertical and
horizontal locks (6 and 10, Fig. 1), then remove the
dust cover from the end of the telescope tube.
Flip the Power Switch (E) on the computer control
panel to the ON position. The lights flicker on the
Electronic Controller. Press any key and the motors
briefly move the telescope. The Electronic Controller is
now operational.
Use the arrow keys (H) of the Electronic Controller to
move the telescope up and down and/or left and right.
To change the telescope’s slew speed, press the
SPEED key (I). The indicator lights signify the speed,
with the upper light showing the highest speed. Each
press slows the speed down one level, then cycles
back to the highest speed.
Sight along the side of the telescope’s main tube to
locate an object. Practice using the arrow keys on the
Electronic Controller to center an object in the
telescope’s field of view. Use the telescope’s focus
knob (9, Fig. 1) to bring the object into focus.
