332 Appendix B: Reference Information Correcting an Error When the TIN73 detects an error, it returns an error message as a menu title, such as ERR:SYNTAX or ERR:DIM MISMATCH. To correct an error, follow these steps: 1. Note the error type (ERR:error type). 2. Select 2:Goto, if it is available. The previous screen is displayed with the cursor at or near the error location. 3. If you select 1:Quit (or press - l or :), the Home screen is displayed. 4. Determine the cause of the error.
