All Owner’s Manuals
Every C O Monitor I made from 2000 to 2010 looked exactly like the one pictured in your attachment.
There is supposed to be a “Date of Manufacture” small square sticker on the bottom right of the rear label.
If you will tell me that date, I can tell you if it is a Model 2002, 2004, or a model 1070.
The “Limited Warranty” on all three should be on page five, , and states on all three that the warranty was twelve months, one year.
Many thousands of your customers have discovered, the “Actual Useful Life” on all my C O monitors, if properly cared for, is five, , years or more.
http://coexperts.com/model-2015-owners-manual/ New Model 2015, This warranty is valid only if the monitor was purchased directly from a licensed contractor or a registered agent of C O Experts.
