The space has an e-ink sign with a suction cup that we use every open night. It is part of the opening procedures.

When opening the space, put the e-ink sign up like so:

The e-ink panel takes in USB-C power. Any USB-C charger will work.

If the e-ink shows an error sign OR if the timestamp is too old, try power cycling it by flipping the switch at the bottom to OFF for a few seconds then ON again. The screen should blink, then the right content should display after a few seconds.

If nothing changes, consider charging it. If it keeps erroring out, please make a Zulip thread about it.
