Audio Line Connection Relays
The Model LE300-IP has relays that disconnect the page, party lines 1 through 5 and the page monitoring
audio output connections from the Main PCBA. The disconnect feature is used for special applications
such as connection of a single party line system, or other scenarios in which a particular audio line is not
physically connected to the line extender. DIP switch SW4 is used to control the audio line disconnect
feature. Refer to Figure 6 for the location of SW4 on the Main PCBA and Table 14 below for setting
options.
