Perform this procedure again. An installation which has a slim line control head or a sidemount control head will have a control station processor (CSP). Do not replace the slim line control head. If the installation has a slim line control head or a sidemount control head, go to Diagnostic Functional Tests, "Control Panel - Test".STOP
