Quote:I have an RCX 400 in a Technical Innovations fiber glass dome. I have not had the two together very long. Is it to be expected that the GPS will shut down when the scope is closed up in the dome? The scope is not keeping the time and date accurately.
Quote:Thanks for that info. I am not clear on this. You say the function of the GPS is to initially find the position of the scope and the rest of the viewing time other components do the tracking?

Ok, equipment list…for reference purposes only!
…Missing my RV-6. Why oh why did I sell it?!?!?!?
Quote:I am not an expert on this telescope, but isn't there an internal little battery in this unit (one of those flat round ones)? If it is going bad could this be causing your problem.
Quote:I tried to get this scope on track this evening. No such thing. When I turned it on I did the calibrate sensors routine and the GPS responded and went to Polaris but it was not very accurate. It did not lose time or date while the scope was on but when I shut it down and turned it back on, it kept the date but lost the time, taking it back to a time I had put into it about 3 nights ago. When I turned it on and told it to do a one star alignment and designated Polaris the hand box told me "Not aligned" even though I thought I had it aligned on Polaris.

Quote:If it is like the LX200GPS scopes, there is a button battery inside that helps the GPS to maintain its ephemeris data between GPS sessions. It performs no other function. And if it is dead, the only impact is much-longer times for GPS fixes.I don't have a RCX-400 scope so I can 't say for sure if it is the same as the LX200GPS scopes in this respect.
