..... My "V" version had the battery changed about 3 or 4 years ago, so it still has 10 years left I guess, although I'm sure there won't be anything left for it to view by then.}

Might be a good idea to "piggyback" a new battery on your 4200V before it goes out as well. These receivers are starting to get old enough that the batteries will be dying shortly...
Yeah, after I read this last night, I plugged in my 4200V to make sure it's still OK and it is. :up
Since my "V" version has a fairly new battery, I wasn't too concerned about it, however I really don't use these receivers too much (but may now, due to some FP stuff ), so I usually don't keep them plugged in. I'm also starting to think maybe I should keep them plugged in just to keep battery drain to a minimum.
