Trace Overlay Off On Press this submenu key to toggle Off and On the trace overlay function. If no valid DTP trace is available, then pressing this submenu key briefly displays a warning message on the screen. For a description of valid trace, refer to Valid Trace. If a valid DTP trace is available, and if DTP overlay trace memory does not contain a valid trace, then pressing this submenu key creates a copy of the active trace and stores it in overlay trace memory. After a valid DTP trace is stored in overlay memory, this submenu key only toggles the view Off and On. |
