6. Operating Instructions
The VEVOR Cash Register Drawer offers three methods for opening:
6.1. Electrical Open (via POS Printer)
This is the most common method for daily operation. When a transaction is completed and a receipt is printed from your POS system, the cash drawer will automatically open. Ensure the RJ11/RJ12 cable is securely connected between the cash drawer and the receipt printer.
6.2. Key Open
Use one of the provided keys to manually open the drawer. Insert the key into the lock cylinder on the front of the drawer and turn it to the 'Open' position. The drawer will spring open.
6.3. Manual Open (Emergency Lever)
In case of power failure or if the key is misplaced, an emergency lever is located on the bottom of the cash drawer. To open, carefully lift the cash drawer and locate the small lever. Press this lever to release the drawer latch.
