Carbon Monoxide Detector - Peak Level Reading Question?

I have the Kidde KN-COPP-3 detector and I'm having a little trouble figuring out how it's operating.

So far I have not had any alarms go off, and I always get a reading of zero. However, today when I came home I had the "Err" error message displayed, and when I tested the Peak Level Memory it came up as "999." When I test now, however, the unit is reading "0".

How can it be possible that I have had a 999ppm reading and the alarm never went off? Could this be due to the error that was displayed today? The unit was safely plugged in when I checked, my only guess for what might have happened was a brief power surge/outage but my neighbors are saying they didn't have anything of that sort.

Just concerned and wondering what this machine is trying to tell me. I'm looking for a customer service number so I can check it myself.

(For reference, I'm not currently nor have I recently experienced any symptoms of C.O. poisoning, but for safety's sake I've opened my windows and done several Tests on the unit.)

Answer
Check you peak reading often, but 999 would be so lethal. I've heard anything more then 100 for a few minutes can be fatal. Most likely it was apart of your err. message. Mine reads a peak sometimes around 16, but the only time i've seen err or high numbers is when the battery is dead, and changing the battery/resetting the unit.
