Tips

To ensure reliable operation, connect the drawer to a powered cash drawer port on your receipt printer. If your printer lacks this port, a dedicated cash drawer kick-out interface may be required. For added security, consider using different key codes for multiple drawers to restrict access. Keep the till clean and free of debris to maintain smooth opening and closing. If you plan to mount the drawer under the counter, purchase the optional brackets and ensure adequate clearance for the drawer to open fully.
