MJ, I have done some tests with my 289 following the process in your video. I have v1.1 and could not get the fault to trigger with a LED torch, incandescent torch, incandescent light or florescent light. However I was able to lockup the my meter with the process 100% of the time in direct sunlight. I also tried a standard TV remote pressing the '1' key rapidly just as it was about to sleep at the 5 minute mark. The screen would flicker like it was going to go to sleep but then would quickly wake up and act normal and continue to log. Kid of like a wakeup call from a PC or something I guess. I'm going to test logging with sleep mode to a PC before I upgrade to 1.16v and then again after to see if the patch affects the logging to a PC in any way. I will also retest the sunlight issue after the upgrade.
