Chart 3 Remove and Replace RF Detector(s)
Main power to repeater must be off.
Prior to removal of detector(s), tag each to identify which is the forward RF
detector and which is the reflected RF detector. Failure to install detectors
correctly will cause the wrong feedback signals to be transmitted to the
main controller. This in turn will cause HPA power problems and inaccu-
rate power readings.
