6. Troubleshooting 

Problem observed 

Possible solution, root case 

Remote controller doesn’t work 

 

You’re out of the range, get closer 

  Battery is down, recharge it 

  Strong WiFi router can be found close to 

the platform 

Target object always leaves the 
frame 

  Check the set latitude 

  Check the pole direction 

  Check the power supply of the controller 

Guiding has a significant RA error 

  Check the tightness of the belt 

  Too windy weather  

Guiding has a significant DC error 

  Check the position of the center of gravity 

of the telescope, maybe it’s too close to the 
DC axis 

  Too windy weather 

Guider gives „Calibration error” 

  Doublecheck the stable balance of the Alt-

AZ axles 

  Try to select another autoguider speed on 

the TEPP controller unit 

  Too windy weather 

Blurry or striped pictures 

  Check the balance and proper fixing of Alt-

AZ axles 

  Try to set another integration time for 

guiding 

  Too windy weather 

Guider shows big deviation for the 
RA-DEC perpendiculars 

  Try to take photos in another time, when 

the target is closer to the meridian 

One of the 12V outputs is not 
working 

  Overloaded output: remove the load, and 

wait 10-15 minutes to recover the internal 
fuse 

  Try to connect your load to another output 

connector 

TEPP is not initialize (continous 
short beeping) 

  Check the cables of the limit switches 

  Check the connectors and cables of the 

TEPP controller unit 

TEPP jumps or slides sometimes 

  Overweighted platform 

  RA belt is too loose 

In peripheral positions the telescope 
willing to fall off 

  Check the position of the center of gravity 

of the telescope 

  Check the center mounting screw of your 

telescope’s base 

  Fix the base to the TEPP using cable ties 

DEC movement lags, or it has 
clicking noise 

  Check the greasing of the DEC axis
