Note: Guiding actions are recorded even when the PEC train-
ing is stopped midway. The PEC + sidereal tracking will not be
accurate until a full cycle of the PEC Training is performed.
The Sirius EQ-G 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 button when needed. In the Setup menu,

choose “Set Tracking”, then “PEC + Sidereal”. The Sirius EQ-
G will play back the corrections you made during the PEC
training cycle and start tracking with periodic error compen-
sated for.
Note: The Sirius EQ-G will continue to track in the PEC +
sidereal mode until another tracking mode is selected. If the
power is turned off while the Sirius EQ-G is in the PEC + side-
real mode, the hand controller loses synchronization 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” in the Utility Functions menu before turning off the
power.
