I’ve tried to follow your steps but can find no “pre-roll activate icon” to activate. The manual does not mention it.
Yes, pressing record does jump the cursor to the Left Locator and begin recording. But it doesn’t pre-roll play the seconds set leading up to the record point. That requires me to punch record at the same second when I need to be seeing the words in the text to read. I need the pre-roll time to scan the text and prepare to read.
