    If your headset is equipped with a mic on/off switch, you can probably use it with the remote mic switch feature of the RM-325. See “Mic On/Off Switch” in the operation instructions, page 15. If your headset does not have a mic switch, but you want to use this feature, you can connect a remote mic switch to the AUX connector.

    RM-325 OPERATION There are several operating features that are configured with internal jumpers and switches.

    3.6 Sending a Talk-off Signal The RM-325 can generate an inaudible signal which can be used to deactivate the microphones on other intercom stations connected to the intercom channel (works with models BP-318, BP-325, BP-350, RM-325, MCE-325 and MRT-327). This feature is useful when there is a microphone activated on an unattended intercom station, and it is causing noise on the intercom channel.
