I communicated with Lifetime ultra tech support about the receiver's clock slows 5-10 min. per 24 hours. They frankly admit the problem with" it's a very good receiver but not a very good clock"
I'm having Fortec Star 2.4, Boot V. 60 made on July 9, 2004, purchased Dec. 2004.
Updating to 2.44 is the solution but they did not mention the new firmware upgrade to me

Go figure.
