5.7 Troubleshooting Using the Output Screen on the
SP4 Telzone Programmer Software
Once the Logical Zone Groups and the Background Music Zone have been programmed and the
configuration has been sent to the SP4-TZC using the SP4 Telzone Programmer software, the USB cable
can be disconnected and the SP4 Telzone Programmer software can be shut down. Subsequent use of the
software is needed when it is necessary to edit the Logical Zone Groups and customize the Background
Music Zone, identify the serial numbers and ordered locations of the SP4-APS splitters, and provide status
information when troubleshooting a problem with the splitters.
Table 7 lists the “Splitter Status” indications listed on the Output Screen. The “Splitter Status” command
is listed under the “System Info” menu.
