Monitor Mode: Monitor Mode is used to monitor the noise in a speciﬁ c room. Place the intercom in the room that is to be monitored and press the Monitor button until a tone is heard. For extended Monitor usage, consider using a plug-in transformer. Any other networked intercom can listen to that room. If a speciﬁ c channel is selected for Monitor Mode then only other intercoms on that channel or on the paging channel can listen. Press the Talk button to exit Monitor Mode. A tone will be heard indicating Monitor Mode is no longer active.

Voice Activation Mode (VOX): Voice Activation Mode (VOX) allows a call to be answered without pressing the Talk button. Once a call is heard on an intercom which has been set to VOX, a response can be given by speaking loudly into the intercom. There will be a slight delay when VOX is ﬁ rst activated by a voice, but will continue to transmit audio until the speaking stops. To put intercom into VOX, place Dipswitch #1 to the UP position. While in VOX mode, a call may be initiated by pressing the TALK button.
