III. Using

There are 2 device for alignment the platform for northern pole. 

Set the compass according to your observing location. You need to check, if is any deviation between magnetic and geological north pole at your location.

Lastly it is needed to set the spirit level according to northern latitude of your observing location. The platform are developed for the middle of the using range.
4045 → 42.5°
4550 → 47.5°
5055 → 52.5°
With the adjustable feets it is possible to change the pole angle. To higher angle you need to lift the front feets of platform or sink the southern feet.

Now you can put the telescope onto the top of platform.

With the slide switch can be switched on the platform, then the platform will resetting itself. If it is done, the tracking will be startad automatically also.

At the end of tracking 3 short beep can be heard, and you have 12 sec before auto-reset. If you push the red button, the platform will not reset itself.

In this case you can start the resetting with long press of red button (min. 2s).

The sound feedback, and the auto-reset function can be switched off. For this you need to take out the control board. Pull down the connector at the rear side of controller unit. Remove the front plate of controller (4 screws), and pull out the board. With 2-pole DIP switch you can swith off the auto-reset function, and the sound feedback.

Is there one more setup possibility. If your mount is not rotatable easily, than you can increase the torque moment of motor, so the moving of mount will be not rotate the top plate of platform. Near to the heat sink you can see a small potentiometer. Rotate them ccw to increase the torque.
