Depending, it's also possible that the new settings didn't take
effect yet. Sometimes the electronic controls can require sort
of a "boot" in order to re-read settings, thus the powerdown
requirement to set it.
I've only seen that on top of the line stuff though; I'm more
inclined to think it was safety as mentioned, but figured it
couldn't hurt to mention the re-read issue.
If it seems like the change didn't happen though, try a power
down/power up first to see if it kicks in the new setting.
