Inquiry (采购产品): R7075-01 Comparator I am dissapointed in the manual that came with my TFC-25D Microline system. Nothing in the manual about the operation of the comparator. Nothing about what to do when the comparator tells ne "Service" Do these comparators go bad? Mine says service and I would like to know what this means. Do you have a short manual on the R7075-01 **** Hidden Message ***** Brad Davis 609 15th Avenue Sterling, IL 61081 USA Company: Home Title: Owner Phone: 815-626-8922 E-mail: bdavis@essex1.com **** Hidden Message ***** bdavis@essex1.com
