charger.
This is normal. The battery is fully charged and maintaining the power.

Make sure that the polar scope is rotated to the proper position so LED will illuminate the dial.
Follow the instruction to adjust the LED brightness.
4. Polar scope illumination is too bright.
Follow the instruction to adjust the polar scope LED brightness.
5. The polar scope dial is not focused?
Please adjust the polar scope eyepiece to focus your eye sight on to the polar scope dial.
6. Can't see star clearly through the polar scope while doing polar alignment?
The polar scope is calibrated in factory for average eyesight. You need to remove the polar
scope from the mount and adjust objective lens. Contact iOptron for an instruction.
7. The star is trailing while imaging?
Polar alignment is critical to the tracking accuracy. Make sure your polar alignment is correct.
The tracking speed is set at 1X for sky imaging. Correct Northern/Southern hemisphere is selected.

position from the 24 hrs dial to iOptron polar scope, you need to divide it by 2, i.e. the
reading on the dial is 10 o'clock, then you should put the Polaris in your polar scope at 5
o'clock.
