I wish there was a ZERO STAR selection. I am on my second unit, and both do the same thing: reboot whenever they feel like it.When I was on the phone with tech support getting an RMA for the first unit, it rebooted over two dozen times in 20 minutes. I just got the replacement unit installed today, and 30 minutes later it was rebooting.I have removed it and reinstalled my older DI-614+I have seen many posts on various sites across the Internet from people who have the same problem. Avoid the DI-624!!!
