Report "Instructions, timer,temp i just bought a 1.5 quart crockpost and eventhough i did come with a small book, it doestn't tell me the temp that it runs at,or what the max time is. can i run it for 8 hours or only 4. it doent have a knob on the front so i assume it has only 1 temp. but is that low or high? i'm usually gone 8 hours at least. i dont want to burn anything. lena"
