If your Sharp CS2850A calculator is displaying a "6" on the screen and the keys are locked, you can unlock it by following these steps:

Locate the "MODE" key on your calculator. It is usually located on the top left or right corner of the keyboard.
Press and hold the "MODE" key for a few seconds until the "LOCK" indicator on the display disappears. This will unlock the calculator.

If the "6" on the screen persists after unlocking the calculator, it may indicate a specific error or condition. Consult the user manual that came with your calculator for troubleshooting information or contact Sharp customer support for further assistance. The manual should provide detailed instructions and explanations for the various error codes or messages that may appear on the display.

Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
