PROBLEM #2:
Incorrect telescope model shown
The hand control does not display the No Response errors
described above, but it does display an incorrect telescope
model when plugged into the mount.
• For EQ mounts, the hand control displays “NexStar Ready”
instead of the model of your EQ mount. If this happens, you
will need to change the firmware using Celestron Firmware
Manager. We’ll explain how in the next section.
• For AZ mounts, the hand control displays “Advanced GT”
instead of the model of your AZ mount. If this happens, you
will need to change the firmware using Celestron Firmware
Manager. We’ll explain how in the next section.
PROBLEM #3:
BOOT LOADER Errors
Whenever the hand control is in the firmware boot loading
mode, then “BOOT LOADER” will appear on the the top line
of the LCD. The line below it will provide additional information,
common examples include “User keypad request”, “CFM
request”, “Pass Through Engine”, and “Invalid Package”.
In the case where the hand control is trapped in boot loader
mode, for any error message save for “Invalid Package”,
simply power cycle the hand control to resolve the issue.
To do this, the mount should be powered off, and if the
hand control is connected to a PC via a cable, it should be
physically disconnected from the computer. Then reconnect
the hand control to the mount and turn the mount back on.
In the case where BOOT LOADER appears on the first line
of the LCD and “Invalid Package” appears on the second line
of the LCD, you will need to reprogram the hand control with
the Celestron Firmware Manager. We’ll explain how to do this
in the next section.
