Insert one of the provided keys into the lock cylinder on the front of the cash drawer. The lock has multiple positions:
- Locked Position: The drawer is secured and cannot be opened.
- Manual Open Position: Turning the key to this position will manually open the drawer.
- Online Position: The drawer is unlocked and can be opened electronically via a connected POS system or printer.
Familiarize yourself with these positions before connecting the drawer to any system.
4. Connecting to a POS System/Printer
The MB30 Cash Drawer supports two primary connection methods:
- RJ11 Interface: Connect the RJ11 cable from the cash drawer to the designated cash drawer port on your POS printer or system. Ensure the system's software is configured to trigger the cash drawer.
- USB Trigger: For systems without an RJ11 port or for direct PC connection, use the USB trigger. Connect the USB cable from the cash drawer to an available USB port on your computer or POS device. Install any necessary drivers if prompted by your operating system.
Refer to your POS system or printer manual for specific instructions on cash drawer integration and driver installation.

- Manual Open: Insert the key and turn it to the "Manual Open" position. The drawer will spring open.
2. Organizing Currency
The cash drawer features a 5-bill tray and a removable 8-coin tray. Arrange bills and coins in their respective compartments for efficient cash handling.
3. Closing the Drawer
Gently push the drawer inward until it clicks securely into place. Ensure it is fully closed to prevent accidental opening and to maintain security.
4. Emergency Drawer Release
In case of power failure or system malfunction, an emergency release tab is located on the underside of the cash drawer. Consult the diagram in the troubleshooting section for its exact location and operation.
Maintenance
1. Cleaning
Wipe the exterior of the cash drawer with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish. Ensure no liquids enter the internal mechanisms.
2. Drawer Mechanism
Periodically check the drawer slides for any obstructions. Keep the area around the drawer opening clear of debris. Do not lubricate the slides unless specifically instructed by Royal support, as this can attract dust and hinder performance.
3. Key Care
Keep the keys in a safe place. Do not force the key if it feels stiff; ensure it is fully inserted and aligned before turning. If the lock mechanism becomes difficult to operate, contact customer support.
