Some CO conditions may start out as low level leaks but could develop into CO
concentrations that could become harmful. If this happens, the CO alarm will
detect the dangerous level and alarm, notifying you and others of the condi-
tions. DO NOT ignore high concentration readings above 30 PPM or a CO alarm-
ing device that is in alarm. Refer to page 12 for more details.
CO concentrations displayed below 30 PPM in "Peak Level" memory are for ref-
erence only and the accuracy of the concentration shown may not be as accu-
rate as noted on page 27.
