IR Troubleshooting Guide

NOTE: Due to the many variables in a given installation, the troubleshooting countermeasures you will have to take may vary from job to job. Each installation is different due to the number of IR receivers in use, length of wire runs, type of wire, amount of ambient IR noise present, etc…. Therefore, your

countermeasures for a particular job will range from nothing at all, to any combination of the solutions listed below.
