4.8.7.2. Set Zero Position
This sets the Zero Position for the firmware.
The Zero Position reference may be an undefined value before the first time powering on the mount,
after firmware upgrade, or HC battery replacement. You can use this function to set the zero position
reference.
Press the ENTER button after moving the mount to Zero Position either manually or with the
handset.
4.8.7.3. Search Zero Pos.
Select "Search Zero Pos." and the mount will start to slew slowly and find the R.A. and DEC
position to set the mount to the Zero Position. When the mount has found the Zero Position, the HC will ask
if you want to calibrate the Zero Position. Press ENTER to confirm. Use the arrow button to adjust the
mount in RA and DEC to correct the obvious discrepancy in the Zero Position. Alternatively, press BACK to
cancel.
