The SkyView Pro GoTo system will emit a “beep” sound and 
display “Record completed” when the training time is up. Press 
any button to exit from the PEC Training upon completion. 

Play Back the PEC Record

PEC tracking can be activated under the Setup menu or by 
pressing the Setup quick reference button when needed. In 
the Setup menu, choose “Set Tracking”, then “PEC + Sidereal”. 
The SkyView Pro GoTo system will play back the corrections 
you made during the PEC training cycle and start tracking 
with periodic error compensated. 

Note: The SkyView Pro will continue to track in the PEC 
+ sidereal mode until another tracking mode is selected. 
If the power is turned off while the SkyView Pro is in the 
PEC + sidereal mode, the hand controller loses synchro-
nization with the R.A. worm gear and the PEC training 
will have to be repeated when the power is turned back 
on. To avoid this, be sure to return the telescope to its 
home position by selecting “Park Scope” under “Utility 
Functions” before turning off the power.

to initiate the computer interface mode. The hand controller 
will now communicate with the PC at a rate of 9600 bits/sec, 
no parity and stop bit. All angles are communicated with 16 
bit numbers.
