the rmware you will need to download the rmware loader program as well as
the rmware update le. Both are available at the Sky-Watcher website in the
downloads secon. Follow the steps below to update the rmware:

Loader” V1.63 or higher from the Downloads page. You will need this program
to load your rmware updates.

5. Run the Motor Controller Firmware Loader and select the rmware le you
downloaded.
6. Select “auto-detect COM port”, then click on “Update”. Please do NOT turn o
