Sensor end

This C O – Experts Low Level C O “Health” Monitor is doing EXACTLY what it was designed to do. It is telling you that it is no longer protecting you.
This C O Monitor MUST be replaced IMMEDIATELY because this C O Monitor is no longer detecting C O, NOT EVEN AT EXTREMELY HIGH LEVELS.

This Warning is based on the decrease in sensor activity and indicates this sensor has degraded to the extent that it is no longer protecting you. This Warning is possible because of the “Full-Time” monitoring of the sensor designed into all C O Experts C O Monitors.

Your replacement charge for a new C O Monitor would be $179. _ with free shipping.
If you decide to order a new C O Monitor I will need for you to put a note in with your check telling me the Serial number on the old Monitor that you are replacing.
