Assembly
First remove the flexible shaft. Bring the entire assembly to the horizontal
(illustration A). Remove the black plastic cap by undoing the small screw on
the back so that the motor guide on the R.A*. drive side of the telescope
mounting is exposed. Now insert the motor in the mounting guide using the
dovetailing (illustration A). Make sure the motor shaft points towards the
mounting drive shaft. Insert the long Allen screw (5) through the drill hole on
the back of the mounting to fasten the RA* motor in place (the upper decl**
motor is secured to the mounting with the short Allen screw (6). Initially
tighten the screw/s only hand tight. Which motor is mounted where doesn't
matter, as they are identical. Now install the enclosed sets of cogs on the
drive shafts as shown in (illustration B). Align the cogs on the axles (illustra-
tion C) so that they interlock. The grub screws must face the flattened shaft
side as in (illustration B) before being tightened.
The motor fastening screw can now be tightened.
Please then check the position of the cogs again. They must not be slanted
or press hard against one another.

Commissioning
Insert eight Mono type batteries in the battery box (3) and make sure when
doing so that their polarity is correct. Now turn to the manual control system
(2) and connect the motor (1) cables as illustrated. The R.A*. marking is
connected to the hour drive (lower motor) whilst the cable marked Decl.** is
connected to the declination motor (upper motor).The battery box (3) cable
can now be connected to the DC power socket of the manual control system.
Operation
To ensure correct tracking the mounting must first be aligned to the celestial
pole (see Operating Instructions). To turn on, the right sliding control is set to
„N" (when in the northern hemisphere), or S in the southern. Tracking then
commences automatically. Use the direction buttons to make corrections.
The yellow buttons move the telescope north/south and the white ones move
it along the hour axis (right ascension). Use the left sliding control to set the
correction speed - 32x, 8x or 1x. 32x is suitable to centre an object in the
viewfinder or eyepiece. 8x is suitable for making fine corrections. 1x is for
very fine corrections, e.g. in astral photography.
Note
Instead of using batteries the control system can also be powered from
the mains using a standard mains power unit or from lead accumulator
batteries. Make sure the connecting plug has the correct polarity (check the
specifications) and that the power supply is a constant 12 V DC.
The stepping motors warm up after lengthy use. This is quite normal and not
a sign of malfunction.
