Step one is to set up the hand controller. It's important that the Time is correct and your location(longitude and latitude) is correct as well. Without these two settings accurately set you'll never get aligned.
1) IMPORTANT: You'll need to align your finder scope(yours looks like a red dot illuminated unit in the diagram) with the main scope to assist you in pointing to and centering stars. You can do this with ground objects like a very distant blinking tower light for instance or use a bright star(Polaris is good because it won't drift on you while you're adjusting). You'll do this with the mount turned off(not tracking). First mount the finder to the telescope if it isn't already. Then place an eyepiece(20mm or so will be good, don't try it with a 4mm or 10mm, that's too much magnification) in the scope focuser like you would for viewing. Next point the scope at the distant object and look trough the eyepiece(not the finder) until you see the object, and center it in the eyepiece field of view. Tighten things down so it can't move. Now adjust the finder scope with the adjustment screws until the distant object is centered in the finder just like it was in the eyepiece. Once you've got the object centered in biot the eyepiece and the finder scope you now have an accurate way of pointing the scope, much like a rifle with a scope.
2) Set up scope/tripod in a place with a clear view of the northern sky, and as much of the rest of the sky as possible too.
3) Level the tripod/mount. Use a small bubble level or carpenter's level if the tripod does not have one built in. Being level allow the mount motors/gears to operate with minimal stress.
4) Locate Polaris(north star). It's the top and brightest star on the handle of the Little Dipper. If you use a compass to find north that will point you toward Magnetic North which is just west of true north. If needed you can use a compass to find magnetic north and then look several degrees to the east of that spot and you will see Polaris about 30 degrees up from the horizon.
5) Point the scope so that Polaris is centered in the eyepiece of the scope and double check the finder scope to be sure it is centered as well(should be unless it was bumped).
6) Now follow the prompted procedure of the hand controller. You'll have to select a star so it helps to know the brightest stars in the sky at the time you are setting up. The brighter they are the easier they are to see and you'll want to choose stars the scope will have a clear shot at, no trees or houses in the way for example. Once the mount motors to the star you select, look through the finder scope(nice wide view to help find the star) and using the hand control motor the scope to move the star to the center of the field of view. Look in the scope eyepiece and make sure it's centered and push the button on the hand controller that say OK or whatever to indicate you have it centered. The hand control should then ask you to select a 2nd star. Repeat the same process you did with the first star and hit OK and it should say alignment complete or something like that. Now you should be able to select objects from the controller and accurately motor to the object.
It all seems complicated at first but after doing this a few times you'll get faster at it and hopefully more accurate too. Hope this helps.
