Vixen AGA-1 - Manual (Page 14)

PAUSE MODE
This mode allows you to discontinue the auto-guiding momentarily
when the guide star is about to go behind the clouds.
Ⓓ! Pressing the “Pause” key
By pressing the “Pause” key, you can discontinue the auto-guiding
momentarily.
The key should be pressed before the guide star goes in behind
the clouds.
If you delay pressing the key, the guiding error may occur.
Even if the auto-guiding is discontinued by pressing the “Pause”
key, the motor drive will continue running at the normal guide
speed.
Ⓔ! Restarting the auto-guiding
As the data of the Level Check and Drive Check Mode are not
erased even after the “Pause” key is pressed, you can restart the
auto-guiding by pressing the “Guide” key.
When changing the guide stars, do the setting procedures over
from the Level Check Mode.
