•Using the battery? Are the batteries installed correctly? Are the batteries fresh? How long have they been used? (frequent slew and GOTO will deplete battery power very quickly)

•Using AC or DC adapter? Check the plugs to the mount and to the power outlet.

•Using extension cord? Make sure the cord is in good condition. Power drop along the extension cord was known to cause the problem. Also check all the plugs and connections.

(4)If the telescope does not respond to commands, set the power switch to OFF and then back to ON.

(5)If the telescope does not slew after power is applied or if the motor quits or stalls, verify that there are no physical obstructions that would impede telescope movement.

Cannot seem to focus (No image appears in the eyepiece):

(1)Confirm that the dust cap has been removed from the telescope.

(2)Keep turning the focus knob. Your telescope has a fine focusing mechanism which allows you to focus an image very precisely. However, this means that you may have to rotate the focus knob 20 to 40 complete turns to achieve focus, particularly the first time you use your telescope. After that, fewer turns will be needed.

Images through the eyepiece appear unfocused or distorted:

(1)The magnification used may be too high for the seeing conditions. Back off to a lower power eyepiece.

(2)If inside a warm house or building, move outside. Interior air conditions may distort terrestrial (land) or celestial images, making it difficult, if not impossible, to obtain a sharp focus. For optimal viewing, use the telescope outside in the open air instead of

observing through an open or closed window or screen.

(3)If viewing a land object on a warm day, heat waves distort the image.

(4)The optics within the telescope need time to adjust to the outside ambient temperature to provide the sharpest image. To "cool down" the optics, set the telescope outside for 10 to 15 minutes before observing begins.

Error Message “Warning! Motor driver overloaded.”

(1)Check the hand controller cord. Unplug it and re-plug into, or plug it into another HBX port.

(2)Check the power source.

The telescope does not GOTO the right object, or the alignment is always wrong:

(1)Leveling (very important).

(2)Site information (minutes ahead or behind UT, DST).

(3)Check the power source.

6.4. iOptron Customer Service

If you have a question concerning your telescope, contact the iOptron Customer Service Department. Customer Service hours are 9:00 AM to 5:00 PM, Easter Time, Monday through Friday. In the unlikely event that the telescope requires factory servicing or repairs, write or call the iOptron Customer Service Department first, before returning the telescope to the factory, giving full particulars as to the nature of the problem, as well as your name, address, and daytime telephone number. The great majority of servicing issues can be resolved by telephone, avoiding return of the telescope to the factory.

It is also suggested to send technical questions to support@ioptron.com.
