Dear Customer:

Please note that the text on the back panel for the Tone Generator is reversed for the Alert and Evacuation tones. When the
contact labeled Alert is activated, the evacuation tone is produced. When the contact labeled Evacuation is activated, the
alert tone is produced.

We apologize for this misprint. For Technical Support, please call 1-800-342-6939.

The figure below shows the proper configuration.

Also, in the Quick-Start Guide, the wiring between the Priority Switch connector and Tone Generator connector should look like
the figure below. If your microphone has a single-pole push-to-talk switch instead of a double-pole, use three separate switches.
