Sony ER-A420 - Manual (Page 185)

The till in the register is detachable. After closing your business for the day, remove the till from the drawer and
keep the drawer open. To detach the drawer, pull it forward fully with the till removed, and remove it by lifting it
up.
The drawer automatically opens normally. However, when power failure is encountered or the machine
becomes out of order, slide the lever located on the machine bottom toward the rear. (See the figure below.)
The drawer will not open if it is locked with a drawer lock key.
