I’m sorry for the delayed reply to your message.  Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was? 

May I ask what software type and version you are using? 

Hello Theary_Smile56 ,

I am just looping back to this older post. Would you mind sharing what the resolution was, if you remember?

In general, this message means the 8890 GC ALS tower is not being detected.  We would recommend checking the physical location/position of the ALS tower.
