connecting an audio source
To transmit audio to each intercom, connect AUX INPUT of a intercom to an audio source’s output jack (such as AUX OUT or TAPE OUT) through an audio cable (not supplied). Follow the instructions in the owner’s manual for your audio equipment to play audio.
•If you use the AUX broadcasting feature and also use the weather radio inputs, you
MUST connect the Weather radio alarm’s output to the unit that is using the AUX broadcasting feature. The weather radio inputs must not be connected to a unit that
NOTES is RECEIVING the broadcast.
•Always connect the weather radio’s alarm output to the intercom you frequently use to broadcast.
•If your audio sources cable does not have the appropriate connector to attach to the intercom, use an adapter available at your RadioShack store or at RadioShack.com.
listening to an audio source
•Each intercom can broadcast from a connected audio source only when the channel to which it is set to is not being used to transmit voice from one intercom to another.
•You can only broadcast from one intercom at a time.
•Adjusting VOLUME on the intercoms does not change the intercom’s input sensitivity.

connecting a weather radio
To transmit weather alerts to each intercom, connect the WX INPUT of a intercom to your weather radio’s ALERT OUT terminals. Follow the instructions in the owner’s manual for your weather radio to create a weather alert.
•If you connect an intercom to both a weather radio and an audio source and both sources are playing at the same time, the intercom always sounds the weather alert first.
•The intercom’s weather alarm will only shut off after the weather radio alerts expire or after you manually stop the weather radio alert. To avoid disturbing neighbors/pets if you are away from the weather radio, turn off the intercom or lower the volume before leaving.
•To stop the alert from a weather radio, it is recommended to manually reset the ALERT OUT terminal of the weather radio. For example on the RadioShack
•The RadioShack Cat.
