Help with the temp on my crock pot
The Rival Crock Pot manuals are available online at this link:

You can always look up your specific or similar pots and confirm the settings with these posted manuals. 

In looking through these, the general norm appears to be that as you turn the top of the dial to the right, you increase the temperature, and as you turn it to the left, you decrease it. Also settings of II and III are usually hotter than I.
