No not that I know of...it has a on and off button and I keep mine on constantly it says the battery last up to 6 months which is pretty accurate because I set mine up about 5 months ago and they're still working.

Yes. At least one of the four battery level lights should come on, depending on how much charge is left.

Don't know. There is a UV light in the base but on mine it is always on. Pushing the button doesn't do anything.

If you mean turn it off as opposed to reducing the light, yes, there is a button on the unit. This Rite Lite does not dim.

If the light isn't in lockout mode, it will turn on full bright with a full press of the button. With a half press it will turn on and allow you to cycle through the brightness levels.

You can program a calculator key. Illumination can be turned off, and it does go dark when the computer turns off.

No, it only illuminates when you are pressing buttons. Stays lit for only a few seconds afterwards.

There's a button on the battery compartment you have to push to turn it on. Then the light should come on whenever it's dark out

Yes. Press and hold the button on top to reveal the backlit dial. The glow in the dark hands are only useful to me when i hold it close to my face.
