The AD696/B base is designed to be used in conjunction with the AD615/S audio encoder system.

speaker in a simple way:
•
Press the Talk button to spread the announcements and keep it pressed
•
Speak clearly and quietly a second after pressing the button to give his announcement
•
At the end of the announcement release the button
The selection lever on the AD615/S system must be in the central position. In case AD615/S is used for diffusion of
background music in the environment, the lever must be placed upwards. For further information on the AD615/S
system and its operation, refer to its specific user manual. Any background music broadcasted by AD615/S will be
replaced by the microphone message during its emission.
The microphone volume adjustment trimmer in the AD615/S system must be set to ¼ turn from the minimum
setting (if you want to check this, turn it all anticlockwise and then turn it in ¼ turn clockwise). Adjust it if necessary
