4.5.4 Command Set 3 -- Emergency Broadcast
The following text describes one way of using the DAI-2 to help meet EAS obligations. It is not meant to
suggest that this is the way to install the DAI-2 to be "FCC legal". There are many ways to install the DAI-
2 as part of an effective EAS system, however, we suggest that you discuss your proposed system with
your communications attorney or the FCC before installing the DAI-2. Personnel using the DAI-2 must
have adequate knowledge of station EAS procedures to use this tool effectively.
Command Set 3 is factory programmed as a control unit for emergency broadcasts. In this configuration the DAI-2 is
used to switch audio and control an external receiver from a remote location. A suggested connection diagram is
given in the Installation section of this manual to operate the DAI-2 with this command set.
Establish a connection to the DAI-2 from a remote telephone and enter the security code. Once in the operating
mode, the keys will function as follows:

The "MONITOR" keys will send audio from the selected source to the telephone while leaving the air audio source
alone. If the telephone is the air audio source it will be muted when the monitor source changes. The "ON AIR" keys
change the source of the air audio and automatically switch the monitor to air audio.
