Testing and Troubleshooting
Generating Audio Test Signals
The Model LE300-IP Line Extender is capable of generating several testing waveforms onto the audio
lines of the Page/Party
® system to aid in system testing and troubleshooting. Rotary switch SW1 on the
Main PCBA determines which Page/Party ® audio line will receive the test waveform. DIP switch SW2
determines which testing waveform is generated. Closing DIP switch SW2-8 enables the test waveform.
Switches SW2-5 through SW2-7 select a test waveform. Note that the frequency selections are different
on the selected audio party line. Refer to tables below for valid switch settings.
