I have some auto-light switches in my home. The one in the image below has nothing in the LCD display and is non-operational. How do I fix that? Manual operation does not work either.
Below the buttons is what looks like a battery compartment. Gentle prying with a screwdriver was unable to open it.
At the top of the switch is another slide-button. I can move that to the right but not the left. The light doesn't work in either position.
Does anyone recognize the brand of this light switch and if there's an operator's PDF around? (In addition to any ideas on how to fix this…)
The other light switches in the house that are like this operate normally.

Looks like it might be an EJ500 Astro In-Wall Timer, or similar device. Here's a link to the Installation Instructions (PDF).
According to the instructions, the switch at the top of the device is an "air gap" switch. Which is "designed to turn power off for routine maintenance".
You remove the battery holder "by prying left and right of the holder with the tip of a flat screwdriver, then pry the battery holder up."
There's a another document available, describing the battery installation/replacement (PDF).
I'm not familiar with this device myself, so I'm not sure if it's fixable or if it should simply be replaced. You might try changing the batteries and see if that helps, as the instructions mention changing the batteries if the display is dim.
