Donation Station Express: Fitting and removing the device in the enclosure
To remove the card reader from the enclosure:
Turn the enclosure around so you are looking at the rear, and locate the locking screw on the right.
Unscrew the lock by turning it anticlockwise. You do not need to unscrew it all the way.
Slide the tray out using the handle to access the card reader. If you ever need to remove the card reader from the tray, there is a hole in the rear that allows you to push it out.

To place it back in the enclosure:
Place the card reader back in the tray. When looking at the card reader in the tray, the locking hole should be on the left.

Slide the tray back into the enclosure.
Turn the locking screw clockwise to secure the tray in position.

There are holes in either side of the tray that can be used to access the charging port (to connect the power cable) and the security cable.
