Now you can turn on the unit. After your viewing session -- press "menu" -- then "Park Position" This will bring your telescope back to the original Park Position. As long as you don't move your telescope-- you can simply turn on the unit the next time you use it. Otherwise, just go through these steps again.

First, walking through the Quick Start Guide is the best help. It provides pictures for each step.

But, briefly, here is what you need to do:

1. Put telescope physically in park position (see other FAQ)
2. Turn on unit. Press "menu". Press "set up controller".
3. Next, you'll need to enter the following information:

• Latitude and Longitude (Google Map or http://www.gps-coordinates.net)
• minutes "behind" UT (ex. East coast is 300 behind UT. West coast is 480 behind UT)
• Daylight Savings Yes or No (some models use "X" for no and a check for yes)
• Time should be entered using military format (ex 8pm is 20:00)

You can find your "time zone" information online at websites such as http://www.timeanddate.com/worldclock/.

No. The 8403 or 8405 hand controller does not have a USB port and so its firmware cannot be upgraded via a local computer.

They have slightly difference in the MENU structure. The 8402 (also called 8402A) hand controller can also be used for an EQ mount or a wedged A/A mount, such as a SmartStar-A mount. The 8402G has 50,000 objects, whereas, the 8402 has 80,000 objects.

If “#8402G Ver[sion]….” is shown when the hand controller is turned on, it is an 8402G. Otherwise, it is an 8402 controller.

No, if your unit works fine upgrading is not necessary.

Our SmartStar^TM GOTO mount (a.k.a. The Cube^TM) is compatible with most OTA's if the total weight is under 11 lbs.

The key factors are the dovetail connection and weight. If your OTA has a Vixen type dovetaildovetail connection and fits the weight limit of less than 11 lbs. (including eyepiece, finder scope, camera or other accessories), it will be compatible with the Cube mount. And remember to always balance your tube during attachment to prevent slipping. If you do not have a dovetail connection -- attach your OTA using mounting rings and connector (available at your local telescope store or your OTA manufacturer). Dovetail plates are also available on our website.

The overall performance will be affected by many factors, such as total weight, OTA size or length, wheather conditions and observing conditions.
