My 880 is pretty flaky, but I think I know how to set it in the charger just right. I'm not sure how well my wife sets it in the charger, however.

The first night I had the remote, I thought I placed it in correctly, but I woke up with only one bar? Now I realized I just need to make sure it only makes one beep and I see the screen saver kick in. Occasionally it does two beeps and I know it isn't sitting properly. Also, I have heard it beeping like crazy in the middle of the night. It appears as if one second it is making contact and another second it is not making contact. So then I hear one beep, two beeps, one beep, two beeps, etc. It is my belief that the remote is not heavy enough to press down on the contacts very well. This is a design flaw, but overall I am satisfied with the remote.
